The Lightweight Machine-to-Machine Enabler (LWM2M) is a new standard for the management of devices in machine-to-machine and Internet-of-Things applications. LWM2M is particularly aimed at resource-constrained end-node devices in applications such as Wireless Sensor Networks as well as Machine-to-Machine applications where bandwidth is constrained – for example where cellular connectivity is used to network remote devices.

Many devices in the growing industrial and commercial M2M and Internet-of-Things markets require some device management – devices need to be remotely switched on and off, woken up and put to sleep, sent remote requests for sensor data transmission, configured, provisioned, or remotely updated with new firmware.

In short, these devices call for protocols and services to effectively support them with device management, service enablement and application management. The design goal of LWM2M was to create a mechanism that is not only suitable for relatively powerful devices like smartphones or Wi-Fi routers, but also caters to the needs of more constrained devices – end-node IoT devices with low-cost hardware, with very limited memory or CPU capability, or devices that run off batteries with very low power budgets.

LWM2M is being developed by the Open Mobile Alliance – a collaboration of many companies working in the M2M service provider, software, hardware and system vendor space. For example ARM and Sensinode are just a couple of the companies involved in the Alliance.

As LWM2M is built on top of open standards defined by groups such as the Internet Engineering Task Force, it allows for interoperability between different devices and manufacturers, avoiding lock-in to proprietary standards.

For example, the LWM2M protocol stack is built on top of the Constrained Application Protocol (CoAP), which is an open IETF standard, as the underlying transfer protocol that is carried over UDP or SMS. CoAP is optimised for communications in resource-constrained or bandwidth-constrained network environments, which makes it well suited to Internet-of-Things applications, enabling the use of low-cost microcontrollers in prolific network-connected devices.

The decoupling of machine-to-machine products from their proprietary, vendor-specific management systems through the adoption of open interfaces and open standards can, theoretically at least, also accelerate innovation in the M2M/IoT markets both on the device side and on the server side.

In essence, LWM2M is a communications protocol running between LWM2M software clients running on all sorts of embedded end-node devices and LWM2M servers running on the M2M management platforms for these devices. The LWM2M protocol includes robust security of all communications between the client and the server using Datagram Transport Layer Security (DTLS), which provides a secure channel between the LWM2M client and the server for all messages interchanged.

The DTLS security modes supported by LWM2M include both pre-shared-key and public-key modes, providing support for robust security across both more capable embedded devices as well as very resource-constrained devices where public-key authentication is not practical.

LWM2M supports UDP binding with both CoAP and SMS, meaning that communication between the LWM2M server and the client can happen over SMS or CoAP, and low-cost basic cellular modems that can communicate over SMS without Internet connectivity can be used to build LWM2M networks.

This also means that LWM2M-equipped networks can be deployed almost anywhere in the field, without the need for modern Internet-capable telco mobile network infrastructure – the network only needs to be able to support SMS messaging.

LWM2M provides an extensible object model that enables application data exchanges in addition to the core device management features such as firmware updates and connectivity monitoring.

A RESTful style of architecture is applied to this, where the items to be managed on a remote device are considered “resources”. Uniform Resource Identifiers, or URIs addresses these resources on the network, which are much like the familiar URLs used on the Web.

Built-in resource discovLwm2m 1ery is supported using the CoRE Link Format standard, making the discovery of new resources on the network relatively easy. Related resources are grouped together into Objects, and this helps to cut down on processing overhead as the M2M client and the server on the platform side have a common understanding of what a certain resource actually is, by understanding the properties of an object that it is a part of – for example the manufacturer’s name, the type of network the device is currently connected to, the signal strengths of the cellular connection it uses, or other relevant properties.

Though the LWM2M specification comes with a set of predefined objects and resources, the set of objects is extensible. This means that other organisations and users can define new objects that are most suitable for their products and services in their particular corners of the M2M market.

The Open Mobile Alliance provides their LWM2M DevKit in the form of an add-on plugin for the Mozilla Firefox Web browser, which is an implementation of the Lightweight M2M protocol, which enables you to directly interact with a LWM2M server from the Web browser on your PC.

This allows developers and users to easily get started, to interactively explore and comprehend this new protocol for machine-to-machine communication.

However if you are interested in upgrading existing products or developing new M2M-capable devices that could benefit from this new lightweight M2M initiative, getting started is easy.

Kaa is a highly flexible, open-source middleware platform for building, managing, and integrating connected Internet-of-Things applications. The Kaa IoT platform aims to provide a standardised approach for integration and interoperability across connected products. With a powerful back-end Kaa speeds up IoT product development, allowing product developers to concentrate on maximising their product’s user experience and unique value to the consumer.

The Kaa middleware supports multiple client platforms by offering endpoint SDKs for various different platforms and different programming languages, and Kaa’s “data schema” definition language provides a universal level of abstraction to help achieve cross-vendor product interoperability – making it a very agile and flexible platform, with standardised methods for enabling integration and interoperability across connected products.

Kaa is designed to be robust, flexible and easy to use, enhancing your IoT products out of the box with a variety of functions. Thanks to being licensed under the business-friendly Apache 2.0 open source license, including the server and client components – Kaa is completely open source and it is free to use in open source or proprietary environments with no royalties or fees.

The source code of the Kaa platform is hosted on GitHub, and you can view it as well as making community contributions. Debian and RPM packages are available, ready for installation of the Kaa server on your target platform – after the installation you can use the Kaa Web UI to obtain the endpoint SDK and get started with Kaa.

The Kaa server is architected to scale linearly with the simple addition of nodes to the cluster, providing the capability for large-scale applications. Kaa features logic for on-the-go load re-balancing, based on real-time service demands, SLAs, node availability, server load and performance, providing efficient utilisation of hardware resources. The Kaa IoT platform is a middleware platform that abstracts the underlying data transport mechanism.

This approach offers application architects the freedom to choose a network stack, or a combination of several stacks for various platform functions, that best suits the requirements of a specific product.

Various different protocols and technologies can be used for the lower levels of the network between the server and endpoints – for example Wi-Fi, Ethernet, ZigBee, MQTT, CoAP, XMPP, TCP, HTTP and more, at the relevant layers of the network stack.

The Kaa platform is comprised of the server component and an endpoint SDK that integrates with client applications. When a Kaa server registers a new endpoint, an associated endpoint profile is created. Kaa’s event system performs discovery of the advertised capabilities of each endpoint device and the delivery of the appropriate event messages across devices.

Kaa stores a profile for each endpoint device, which is a snapshot of any data the specific server application needs to know about the endpoint device. This could include information such as OS version, amount of RAM, device operation mode, battery life or type of network connection, for example.

Endpoint profiles can be used to organise the endpoints into groups, and this can be used to send targeted notifications to certain devices, for example, or adjust software behaviour when talking to certain classes of devices. The specification of the profile structure is configured using Kaa’s profile schema definition.

Based on the defined profile schema, Kaa generates the object model to operate against the client side, and handles data marshalling all the way back to the database. Whenever a client updates its profile information, the endpoint SDK automatically sends these updates to the server as soon as a connection becomes available.

An endpoint can belong to any number of groups, which represent independent management entities in Kaa. Grouping endpoints can, for example, be used to send targeted notifications or adjust software behaviour by applying group-specific configuration overrides. When endpoints register with the Kaa server, they advertise the types of event classes they are capable of originating and receiving.

Kaa features a topic-based notification system that enables the server to deliver messages of an arbitrary structure to subscribed endpoints. Events can even be delivered across applications registered with Kaa – making it possible to quickly integrate and enable interoperability between ranges of different devices.

Kaa2

For example, you could enable a mobile application to control lighting, or use data from a car’s GPS to communicate with a home security system, or integrate audio systems from different vendors to deliver a smooth playback experience as you move from room to room. Kaa events are implemented in a generic, abstract way, using non-proprietary schema definitions that ensure identical message structures.

The schema provides independence from any specific functionality implementation details, and Kaa’s logging subsystem performs the collection and storage of structured data that is received from the endpoints.

Depending on the implementation and configuration of server-side log appenders, the Kaa server is able to store records in a local file system, or a variety of big data platforms such as Hadoop or MongoDB, or submit them directly to a streaming analytics system.

The endpoint SDK implements log-upload triggers that initiate the periodic upload to the server of logged data stored locally on endpoint devices. The structure of the collected data is flexible and defined by the data schema – based on the log data schema defined in the Kaa application, Kaa generates the object model for the records and the corresponding API calls in the client SDK. Kaa’s endpoint SDK deserializes received messages into objects, which are dispatched to subscribed client listeners for processing.

Althuogh the Kaa middleware is open-source, this isn’t a negative – it allows the end-user developer to work with the code to meet their exacting needs or create partnerships with other users for greater interoperability between products. You can learn more about Kaa from their website (http://www.kaaproject.org/).

Muhammad AwaisKaa – a new open-source platform for the Internet of Things

The spread of new Internet-of-Things platforms over the last few months hasn’t abated – and a new entry is now morphing from an idea to a funded platform – Konekt.

Konekt is a full-stack platform providing cellular connectivity for devices in machine-to-machine and Internet-of-Things applications, providing a powerful integrated combination of cellular plans, cloud infrastructure and APIs.

Their goal is to simplify the process of making hardware talk, powering the next generation of the Internet; not just in homes with Wi-Fi or whenever you’re in Bluetooth range, but essentially everywhere, any time, through the use of cellular networks.

Konekt focuses on building infrastructure for ubiquitous connectivity, and aims to make sure that integrating this type of connectivity is as painless and inexpensive as possible, allowing you to focus on building great systems and products with connectivity on the go, anywhere.

The Konekt platform features extensive coverage available via Telco networks in over 160 countries, and a range of different cellular plans, allowing you to connect hardware to the Web at an efficient price point with a level of functionality that suits the needs of your application with global accessibility from day one.

Konekt’s cloud-based infrastructure for IoT devices allows you to easily create real-time public and private IoT applications using literally any hardware that can be connected to a cellular modem. The Konekt service employs the 2G and 3G bands, supporting HPSA, GPRS and SMS connectivity. As well as injecting data into the cloud service via (appropriately formed and authenticated) SMS, you can also send data back to Konekt’s Internet services via REST HTTP.

Short Messaging Service (SMS) offerings are typically very costly for embedded M2M applications when compared to the equivalent amount of data service that would be needed to send the same data. However, SMS connectivity is often needed for notifications to users and certain system integrations.

To provide more competitive SMS rates for your connected devices, Konekt offers an SMS-over-IP solution that leverages the over-the-air data service (cellular data, which is much less expensive for the same amount of bandwidth) and their Internet SMS gateway partners. This service is available for all Internet-connected devices, whether Konekt’s cellular network is being used or not.

Konekt provides cellular plans, cloud storage, device management and more, integrated into a single platform in one place. You can track orders and deployment right in your dashboard, and even manage your SIM cards and order more right in the app.

The device management resources are built for developers, with a set of unified APIs and tools provided that enable you to manage, provision and troubleshoot your devices in the field. Konekt provides a simple billing structure, with no complex pricing arrangements or hidden fees, and developers can get started creating an account and trying out the Konekt platform for free.

You can utilise Konekt’s subscription engine to white-label the Konekt portal with your brand and seamlessly bill your end users, with pricing and coverage that scales with a pay-as-you-grow model. Whether you’re in beta or preparing for your first huge deployment, Konekt can be scaled to meet your needs, instead of the other way around.

Security with the Konekt platform has been taken seriously, and provides enterprise-grade security with secured inbound connections, key management, encryption, static IPs, Private Access Point Names and configuration updates all at the push of a button. By default, devices are isolated and they cannot see one another via data or SMS connectivity.

konekt2

Your devices are therefore protected from other compromised devices, eliminating attack vectors, mitigating risk and reducing attack payloads. Devices are secured against unauthenticated incoming connections and SMSs, to protect against off-network threats and potential threats originating from the Internet.

Konekt provides a flexible end-to-end toolkit aimed at every mobile embedded IoT connectivity application, with tools and support for deployments of all sizes, whether you have one device or a million. Konekt provides scalable pricing as well as support options for commercial applications, transparent uptime reporting, strong security features, high data throughput and readiness for the most demanding enterprise-grade applications.

With a public REST API, extensive documentation and API examples, Konekt is built to be developer-friendly, with robust, clean APIs that let you focus on building great products. Konekt provides you with access to both the REST API and a Web-based Device Management Portal, making device management more accessible for non-programmer users.

Konekt’s pricing is based on the amount of data your devices use. Adjust your data usage as you refine your project, utilise Konekt’s cloud services, and choose your support level, with plans that start from just US$1 per month. Data plans are available in over 160 countries so you can connect your product to the Internet just about anywhere, wherever there is cellular coverage.

Data plans are month-to-month and can be changed at any time. Pricing is based on the number of devices deployed, amount of data used per device and the countries you’re operating in, with custom plans available for significant large-scale deployments.

Konekt Cloud is a fully managed, reliable and powerful cloud data broker and database solution. Currently free for all devices (cellular and non-cellular), the Konekt Cloud provides a powerful suite of tools that securely route and store the data your devices generate, allowing you to spend less time building and maintaining complex infrastructure.

The cloud platform enables you to quickly create real-time smart IoT solutions by giving you the components you need such as real-time data access, security, storage, data analytics and machine learning. You can use Konekt’s hosted service or download the service and run it on your own infrastructure.

With a combination of a secure cloud-based IoT service and affordable cellular data, we look forward to the development of the Konekt platform. And if you have an idea for a new IoT-enabled product or would like to add connectivity to an existing device – here at the LX Group we have the team, experience and technology to bring your ideas to life.

Muhammad AwaisAyla Network’s IoT Cloud Platform

In an effort to expand their reach into the Internet of Things marketplace, Microsoft has launched their Windows Internet of Things Developer program – the first in a series of programs aimed at promoting and educating developers in the use of Microsoft products and technologies for the creation of connected devices and Internet-of-Things applications.

Microsoft’s program is aimed at Windows programmers and embedded systems engineers as well as the hobbyist and “maker” community.

Microsoft aims to bring Windows and development tools such as the Visual Studio suite to a new class of connected devices such as the Intel Edison and Raspberry Pi platforms, low-cost platforms that are attractive for both hobbyist and commercial embedded computing applications.

This should bring synergy with existing developers and the needs of marketing and new IoT-enabled product development in the same organisation – existing IT resources can be used to help with IoT development without too much retraining or new hires.

Microsoft wants to combine the accessibility of the successful Arduino platform with the strong community support and proven experience base behind Windows and Visual Studio, allowing you to quickly iterate and expand on hardware and software designs using existing shields and sketches, with strong compatibility with the Arduino platform at both the hardware and the software level.

The Windows IoT Developer Program was announced last year, beginning with Windows support for Intel’s Galileo single-board embedded computing platform. The addition of the new Raspberry Pi 2 to the program has just been announced, including support for a new embedded Raspberry Pi 2 version of Windows 10, which will be freely available for embedded developers and makers who are members of the program.

Microsoft is hoping that this program, and support for the Raspberry Pi and Galileo platforms, will introduce the use of embedded Windows and Visual Studio development to independent developers and the hobbyist and maker community.

Microsoft has ported the Arduino and Wiring libraries to their embedded Windows IoT offerings, so you’ll be using Visual C++ to write code against the Arduino API. It looks a lot like Arduino programming, with some minor differences.

Intel sells their Galileo development boards with a lightweight version of Linux through distributors, but the version of the Galileo board with Windows installed is only available when distributed through Microsoft. The preview Windows image running on the Galileo for IoT toolkit is a custom non-commercial version of Windows based on Windows 8. Microsoft will ultimately make the OS available for anyone who buys the Galileo board, though.

Microsoft hasn’t just stripped down Windows and dumped it into an image you can run on a Galileo. They’ve been making improvements in Windows to better support the kind of things embedded developers want to do. For example, Microsoft’s Lightning functionality is a re-architecture of Windows to make GPIO operations much faster.

The folks at Redmond sensibly see IoT devices as being a huge opportunity both in terms of selling the embedded solutions that power those IoT devices and to make sure the devices connect and pass their data back to a Windows Server on the back end – Microsoft is potentially able to pick up some market share in the emerging IoT sector not only in the “Thing” components, but in the “Internet” component as well.

The ultimate goal of such efforts is to take information collected from billions of devices and feed it into cloud services powered by Microsoft’s Azure cloud computing platform. This is part of Microsoft’s cloud-heavy strategy, with the company previously pushing Windows Embedded as an IoT platform and a gateway to the rest of the company’s information-management fabric, mainly based around their Azure cloud services.

Microsoft has long catered to commercial developers and manufacturers of embedded systems with the Windows Embedded Compact OS, which is used in a range of industrial devices, mobile handsets, health monitors, ATMs and other devices. Microsoft wants to make sure these manufacturers knows its embedded OS can also work for their IoT devices as well.

However Microsoft has stressed that Windows Embedded is not going away and is still an important part of its product range. Windows Embedded Compact is a fully featured OS which supports commercial devices, unlike the new developmental offerings, and it remains Microsoft’s only real-time operating system and is the Windows operating system with the broadest set of ports including ARM and x86 architectures.

In moving to an ARM7 architecture, there’s a wider range of supported operating systems that can run on the Raspberry Pi 2. The processor upgrade means that two new operating systems come into view: Ubuntu Linux and Windows 10. Microsoft has recently announced it will be offering a Windows 10 build for the newest revision of the Raspberry Pi platform later this year, as part of its IoT Developer Program.

Microsoft and the Raspberry Pi Foundation have been collaborating for the last six months on the joint project. With Windows in the mix this potentially opens up the Raspberry Pi to some Windows-centric developers who weren’t previously interested in creating applications for the device, as it would mean learning a new operating system or programming language.

Windows 10

With Windows comes all the development tools such as Visual Studio, libraries and languages such as C# to add to the many tools that can already run on the Raspberry Pi such as Scratch and Python. Microsoft aims to bring their OS, their development tools, services, and ecosystem to the Raspberry Pi community for free, with the intention that you can take Windows 10 applications that you can run on a Surface, a PC or a Windows Mobile phone and now be able to run it on a Raspberry Pi as well.

This offers a wider range of hardware and software development possibilities for any new or existing IoT-enabled product, and here at the LX Group we have the team, experience and technology to bring your ideas to life.

Muhammad AwaisMicrosoft and the IoT

The ESP8266 Wi-Fi System-on-Chip from Espressif Systems is a highly integrated SoC designed for the needs of modern Wi-Fi-connected embedded systems, appliances, sensors and other cost-sensitive, Wi-Fi-enabled Internet-of-Things applications.

This high-performance wireless SoC aims to provide Wi-Fi capabilities in embedded systems with strong functionality at a low cost. It has powerful on-board processing and storage capabilities that allow it to be integrated with sensors or other application-specific peripheral devices via its general-purpose digital I/O ports with minimal development effort and potentially without the need for any separate microcontroller in many typical applications.

The ESP8266 provides single-band (2.4 GHz) Wi-Fi connectivity using the 802.11b/g/n standards and supports WEP, WPA and WPA2 encryption.

The high degree of on-chip integration minimises the bill of materials in your design, with a low-power Tensilica 80 MHz 32-bit processor core, RAM, ROM and GPIOs, power management module, and all RF front-end components such as the clock generation, PLLs, LNA and power amplifier all integrated on the 32-pin QFN chip.

This means that your complete Wi-Fi connected solution requires minimal external components and minimal PCB area. The ESP8266 offers a complete and self-contained wireless networking solution, including an integrated TCP/IP stack – and it can either provide Wi-Fi connectivity and networking functions to a separate application processor in your design or host your application itself in the chip’s on-board application processor.

Where the ESP8266 serves as an external Wi-Fi bridge to a separate application processor in your design, Wi-Fi connectivity is added to the host processor via a simple UART or SPI interface to the ESP8266. As long as your microcontroller has a spare serial UART or an SPI interface you’re ready to go, so you can straightforwardly interface the ESP8266 to essentially any microcontroller in your existing design.

The ESP8266 has also been designed with energy-efficient mobile and battery-powered applications in mind, with an architecture that minimises power consumption and provides a sleep mode and deep-sleep mode to minimise power use in your design at times when Wi-Fi network connectivity is not actively being used.

With a wide range of interfaces including SPI, SDIO, UART and I2C, the ESP8266 can be used for interfacing to external EEPROM and Flash memory, ADC/DACs, external audio codecs, or other sensors and peripherals that can connect to these serial interfaces.

In stand-alone mode at least one external flash memory chip to boot from is needed. The chipset also incorporates 16 programmable general-purpose digital I/O pins, which can be configured in software with a range of flexible interrupt and output options.

Espressif has released a complete Software Development Kit for the ESP8266, along with a VirtualBox Ubuntu image that provides you with a complete ready-to-go tool chain including gcc and all the other tools you’ll need to develop and build code for the Xtensa core in the chip.

Included in the SDK are SSL, JSON and lightweightIP (lwIP) libraries, providing the capabilities for a range of typical Internet-of-Things applications. Example code is provided to demonstrate the use of the chip’s UART, I2C and SPI interfaces as well as general-purpose digital I/O.

Espressif provides an ESP8266 Internet-of-Things SDK, which is specifically aimed at IoT applications. Although this SDK is only partially open source and some libraries are provided as binary blobs, a fully open-source third-party tool chain for development on the Xtensa CPU architecture is separately available.

A range of other third-party software development tools and interpreters are available or in development for the ESP8266, including the nodeMCU Lua interpreter and an ESP8266 port of the MicroPython embedded Python project, allowing you to use these scripting languages if you choose. There is also firmware available for the ESP8266 that implements MQTT-based message brokering for Internet-of-Things applications.

The ESP8266 is notable in that it is one of the few chip-level 802.11 Wi-Fi devices on the market, along with the Texas Instruments CC3000-series chipsets, which is available in small-volume distribution and with publicly-available datasheets and documentation, meaning that this device is accessible to small-volume businesses and small, independent developers in a way that 802.11 chipsets from major vendors such as Broadcom or Realtek generally aren’t.

Alternative Wi-Fi modules and devices such as the Spark Photon offer features such as USB connectivity, more memory, more I/O and a more familiar ARM architecture, but they are more expensive – the Photon is close to USD $20, for example.

The Spark Photon is a very simple breakout board that just provides an antenna and a voltage regulator for USI’s WM-N-BM-09 Wi-Fi module, which implements Broadcom’s standardised WICED ecosystem with a STM32 Cortex-M3 microcontroller core alongside Broadcom’s BCM43362 Wi-Fi radio.

As another example of relatively low-cost embedded Wi-Fi solution, there are similar boards coming from China today for about $10 based on the MXchip MX1081 chipset, which also incorporates the Broadcom BCM43362 core alongside a STM32 microcontroller.

The Texas Instruments CC3200 Internet-of-Things SoC also aims to provide a complete single-chip IoT solution based around an ARM Cortex-M4 80 MHz CPU core and integrated Wi-Fi radio along with a flexible range of digital I/O interfaces and an integrated ADC.

The CC3200 offers extensive, good quality, English documentation, development tools and resources along with an ARM core that is more popular and familiar with developers than the ESP8266’s Xtensa core. The CC3200 is distributed in small volumes and has publicly available documentation and development tools as with the ESP8266, however the ESP8266 has the advantage of its relatively low cost even in small volumes.

Muhammad AwaisReducing the cost of IoT devices with the ESP8266

Every few weeks it seems that a new Internet-of-Things platform appears, and thus we have a new platform to explore – GadgetKeeper.

This new product provides a complete development and application platform for the Internet of Things, a full application design, runtime and intelligence environment which allows you to rapidly prototype and rapidly create IoT solutions to connect your sensors, devices and equipment (“Things”) with people and systems.

GadgetKeeper provides a simple development environment, robust APIs and worry-free hosting, allowing you to accelerate your application development and take advantage of scalability as your application and your number of devices grows. 

You can easily integrate your application with external IT systems through GadgetKeeper’s powerful APIs, web services, and the completely hands-free cloud hosting environment provided by GadgetKeeper that automatically scales to meet any demand, whether you’re serving several devices or several million.

The designers of the platform believe that every smart device has inherently unique characteristics. Therefore, GadgetKeeper models the attributes of any given device with a unique “Thing”. A “Thing” within GadgetKeeper is a model that could correspond to an Internet service accessed externally via the API or a real-world gadget such as appliance, sensor or other physical device.

 GadgetKeeper’s mission is to provide the best IoT software and application platform for developers, manufacturers, service providers and consumers, allowing you to make and use smart, Internet-connected products, send updated sensor information from IoT devices directly to the server, and to control, integrate and manage your devices remotely.

The platform provides server-side JavaScript support, a powerful UI and an API to handle interaction between your things, to manage and to integrate your IoT solutions. You can use JavaScript to program your server side logic – whenever it’s a property, method or event trigger. From your code you can fire events, call methods and properties or call external systems.

GadgetKeeper supports a powerful server-side API for integration with external services, allowing you to interact with services such as email, HTTP, SMS, Twitter and more. Furthermore it supports communication between your things and the GadgetKeeper platform using a selection of many different protocols.

You can connect your devices to the GadgetKeeper API using REST or JSON-RPC over the top of TCP sockets, HTTP or MQTT at the transport layer.

The platform employs a so-called “Reach Thing Model” to model the characteristics of your devices – a full object model for your things including properties, methods and events. Things are not just “data logging” entities, but they are smart objects that can interact with each other and the world. Properties and methods can be handled by a thing or by its server-side proxy, and events can likewise be fired either by a thing or by its server-side proxy.

The GadgetKeeper platform also provides flexible event handling, where events from your things are easy to handle by creating event triggers that “listen” for thing events and react to them in a defined way. JavaScript can be used to define complex event handling logic.

gadgetkeeper2

There is also a provision for a comprehensive capability for event storage and time-series data storage. All events fired by things are recorded to event storage and numerical values are extracted and recorded in time-series data. Data can be displayed on interactive dashboards, which can also be set up for the monitoring and management of your devices.

GadgetKeeper is compatible with popular hardware platforms such as the Arduino, Raspberry Pi and BeagleBone. Machine-to-machine platforms for instrumentation and wireless sensor networks in industrial applications such as the CloudGate and TSTMote systems are also supported.

GadgetKeeper provides usage examples for these platforms, along with documentation and tutorials for the setup and provisioning of these systems to talk to GadgetKeeper so you can get up and running easily.

Integration tutorials are also provided to get you up and running with API integration of your GadgetKeeper Internet-of-Things application into external services such as Twitter.

Overall there is a great amount of promise with the GadgetKeeper platform at this stage, however like every other Internet-of-Things platform there are many options and variables to take into account before selecting the right system for your needs.

And no matter what your requirements are, from concept to final product – here at the LX Group we have the experience and expertise to solve your IoT power problems right through to a whole system to meet your needs.

Muhammad AwaisGadgetKeeper – a new IoT platform for common hardware

OpenIoT is a generic middleware platform for Internet-of-Things applications, which allows you to link together Internet-connected devices and semantic Web services via a friendly user interface, working either in Cloud Computing environments or with a local server.

This platform is available as a Virtual Development Kit, providing a complete cloud solution for the Internet of Things which allows you to easily get up and running getting information from sensor clouds and connecting this information with Web services without worrying about exactly what different sensors are being used.

The OpenIoT middleware enables the easy scalability of sensor networks and the addition of new, cost-effective sensors in an intrinsically flexible framework, and aims to provide a complete middleware for Internet-of-Things applications, connected sensors and wireless sensor networks.

OpenIoT is building a novel platform for IoT applications, funded by the European Union, which includes powerful capabilities such as the ability to compose (dynamically and on-demand) non-trivial IoT services using a cloud-based and utility-based paradigm.

With an aim to facilitate open access to a wide range of technologies for Internet-connected sensors and other objects exposed as “services”, the creators claim that OpenIOT is the first open-source project to provide the means for setting up, managing and using a sensor cloud in this way.

With the ability to support large-scale deployments by co-scheduling access from thousands of simultaneous users to millions of sensors and actuators, OpenIoT will be well placed for all IoT-based solutions of all sizes, and it will have a small number of its own open (public data) sensing services for anyone to send queries to.

The OpenIoT project explores efficient ways to use and manage cloud environments for IoT entities and resources, such as sensors, actuators and smart devices, and the management of utility-based, pay-as-you-go business models for IoT networks and services.

The platform will provide instantiations of cloud-based and utility-based IoT sensor and data management services, using the OpenIoT adaptive middleware framework for deploying and providing IoT services in cloud environments to enable the concept of “sensors as a service” business models for commercial IoT applications.

 OpenIoT supports flexible configuration and deployment of algorithms for collecting and filtering the large volumes of data that are collected by networks of Internet-connected objects, and processing and detecting those events that are determined to be particularly interesting and relevant to application or business outcomes.

 As OpenIoT is a completely open-source project, and all its source code is available for download – developers and end-users can examine and openly use the OpenIoT platform. You can use the OpenIoT source code to create innovative services, to extend OpenIoT with new sensor wrappers, or to improve the OpenIoT platform itself.

 Furthermore, OpenIoT also aims to provide the capacity for semantically annotating sensor data, according to the W3C Semantic Sensor Networks specification, streaming the data collected from various sensors to a cloud computing infrastructure, dynamically discovering and querying sensors and their data, composing and delivering IoT services that comprise data from multiple sensors and visualising IoT data using many different options such as maps and graphs.

 An example application area where OpenIoT has been targeted is the improvement of efficiency in industrial operations such as manufacturing and agriculture. The OpenIoT platform can be used for intelligent sensing in manufacturing environments where it offers rapid integration of data from sensors and other devices in the manufacturing environment, dynamic and intelligent discovery of new sensors in factories, and analysis of data collected from the factory floor.

 The OpenIoT platform enables the dynamic selection of sensors along with the nearly-real-time fusion of sensor data in order to deliver any manufacturing indicators that are required – not just sets of inflexible, pre-configured indicators. This can increase the agility of decision-making and of the manufacturing process.

 One example of this is an agricultural application – where farmers and researchers can benefit from an instantaneous crop performance analysis platform that is powered by OpenIoT, using a wide range of distributed remote sensors gathering various types of data in order to build models that predict crop yields.

openiot2

 Every year Australian grain breeders plant up to a million small test plots of wheat and barley across the country to find the best high-yielding varieties. The Phenonet application developed by OpenIoT in partnership with the CSIRO is an interesting demonstration of the capability of the OpenIoT platform, using advanced sensor network technology to gather environmental data from crop trials at a much higher resolution than traditional methods and providing an OpenIoT-powered high-performance, real-time online data analysis platform that allows scientists and farmers to visualise, process and extract both real-time and long-term crop performance information.

 The Phenonet project enables plant breeders and farmers to compare and evaluate the performance of different grain varieties using real-time measurements from a variety of remote sensors. By combining these measurements with each plant’s genetic profile, plant scientists can distinguish the effects of microclimate and genetics, thus improving the accuracy and speed of plant breeding which leads to better crop quality and increased agricultural yields.

This is only one of an almost infinite number of applications that can be harnessed with the OpenIoT platform.

Muhammad AwaisOpenIoT – Open-source middleware for the Internet of Things

Today, Internet-of-Things and wireless-sensor networks are finding an increasing range uses of consumer, industrial and medical applications. Such networks often employ a large number of distributed nodes, without interconnecting cables, which can’t practically be connected to the power grid – and it is attractive to keep the need for battery recharging and replacement to an absolute minimum through the use of efficient, careful design choices as well as ambient energy harvesting technology.

Power-efficient wireless sensor nodes can take advantage of some form of energy harvesting power supply, employing energy sources such as solar photovoltaic, vibrational energy harvesters or thermoelectric generators to minimise maintenance and extend battery life – possibly completely eliminating batteries entirely – if the power consumption of the system is small enough and a capacitor is employed for energy storage.

Energy harvesting management ICs that manage the accumulation of energy in a capacitor over a period of time to enable short bursts of relatively high power consumption, such as when a node wakes up and transmits a burst of data, are particularly well suited to low-power wireless sensor nodes.

In many applications, solar photovoltaic are the most familiar choice for low-power sensor and telemetry nodes operating outdoors, for example in agricultural and meteorological applications.

Energy-efficient wireless network nodes can be engineered using modern RF microcontroller system-on-chip devices, turning on and off sensors and peripheral hardware devices when they are not required or putting them into low-power sleep modes when not actively in use.

Similarly, the RF transceiver can be switched into a very-low-power sleep state until the microcontroller decides that a transmission of collected sensor data is required. The microcontroller can then wake up the radio, perform the required transmission, and the radio goes back to sleep.

In some cases, a burst of data transmission across the wireless network might only occur when a small, intermittent energy-harvesting power supply has accumulated enough energy in a capacitor to power a transmission.

solar2

With most of the components of the system – the microcontroller, radio and sensors – each kept offline or asleep for the largest practical amount of time, efficiently designed wireless sensor nodes may achieve operating timescales as long as years off a single battery.

Today’s typical wireless RF microcontroller system-on-chips targeted at Internet-of-Things applications typically consume about 1-5 microwatts in their “sleep” state, increasing to about 0.5-1.0 milliwatts with the microcontroller active, and up to about 50 milliwatts for brief periods during active radio transmission.

As an example of the active development in this field, the International Electrotechnical Commission has recently ratified the new ISO/IEC 14543-3-10 standard, specifying a Wireless-Short-Packet protocol optimised for ultra-low-power and energy-harvesting nodes in wireless sensor networks.

It is the first and only existing standard for wireless applications that is also optimised for energy harvesting solutions, aimed at energy-harvesting wireless sensors and wireless sensor networks with ultra-low power consumption.

For a small, low-power embedded device that receives a reasonable amount of sun each day, a moderately small solar panel is perfectly capable of supplying sufficient power, on average, to run a small, basic wireless network node consisting of a microcontroller, some sensors and an embedded low-power Wi-Fi, Bluetooth or 802.15.4/ZigBee radio transceiver.

In many applications, solar photovoltaic is the most familiar, relatively mature choice for low-power network nodes operating outdoors or under good indoor light conditions. However, other technologies suitable for harvesting small amounts of power from the ambient environment exist. For example, a wireless sensor node set up to monitor bearing wear in a generator could employ a piezoelectric crystal as a vibrational energy harvester, converting motor vibration into usable energy.

As an example of a controller IC one may use for the power supply in a small solar powered system, the Linear Technology LTC3105 is a high-efficiency step-up DC/DC converter that can operate from input voltages as low as 225 millivolts, with a built-in maximum power point controller (MPPC). As well as solar cells, this device is well suited to other low voltage, high impedance energy harvesting transducers such as thermoelectric generators.

For some systems it is also practical to use batteries alone – for example, lithium-ion, lithium-polymer or nickel metal-hydride batteries – and rely on user intervention to simply recharge and replace the batteries where needed.

Lithium-ion batteries provide good energy density and many convenient cycles of repeated charge and discharge, but these batteries require precise control to avoid over-discharge or over-charge conditions which can permanently damage the battery.

Despite their risk of fire and damage if mishandled, lithium-ion batteries provide very good discharge current capability, high energy density, and the ability to survive many repeated charge cycles embedded inside devices which are charged and used without their battery being replaced.

Libelium’s WaspMote platform is an open-source wireless sensor network platform specifically focussed on the implementation of low-power modes, allowing individual battery-powered nodes (or “motes”) to be completely autonomous and to run for many months or years without maintenance.

Depending on the duty cycle, types of sensors and the radio used, it is possible for a WaspMote node to run for as long as five years on a single battery, making WaspMote one good example of a hardware and software platform that is well suited to the use of solar power and other energy harvesting technologies in energy-efficient wireless sensor networks and Internet-of-Things applications.

Muhammad AwaisThoughts on powering IoT nodes

The Industrial Internet Consortium, or IIC, is a global not-for-profit partnership of industry, government and academia which was founded early in 2014 to bring together many different organisations and technologies which are well placed to accelerate the growth of the “Industrial Internet” by identifying, assembling and promoting best practices in the development of industrial Internet, machine-to-machine and “Internet-of-Things” technologies.

 The diverse membership base of the IIC includes large and small technology innovators, vertical market leaders, researchers, universities and government organisations.

 The goals of the IIC are to drive innovation through the creation of new industry-oriented use-cases and test beds for real-world industrial Internet applications, to define and develop the reference architectures and frameworks necessary for interoperability in Industrial Internet applications, to influence the global standards-development processes for Internet and industrial systems, to facilitate open forums to share and exchange real-world ideas, practices, lessons and insights, and to build confidence around new and innovative approaches to security in industrial embedded systems with network connectivity.

 Membership of the Industrial Internet Consortium is open to all entities and organisations with an interest in accelerating the implementation of the Industrial Internet using open standards, and a revenue-based system of membership fees makes membership accessible to academics and small companies.

 Founded by AT&T, Cisco, General Electric, Intel and IBM – the IIC’s goal is to become as an open-membership consortium to try and break down the barriers of closed technology “silos” to support better access to big data – with improved integration of the physical and digital worlds, unlocking enhancements in business value for industry. Today, the list of IIC members includes ThingWorx, Bosch, Telstra, the University of Pennsylvania, and many more.

 The consortium formed in the belief that as the physical and the digital worlds collide through increased use of machine-to-machine and Internet-of-Things technologies, particularly in industrial applications, organisations need to be able to more easily connect and optimise assets and operations to drive agility across all industrial sectors.

 These goals can be reached by identifying the requirements for open interoperability standards and defining common architectures to connect smart devices, machines, people and processes that will help to accelerate more reliable access to big data from industrial systems and hence unlock yields in business value.

 With their aim to take the lead in establishing interoperability across various industrial environments for a more connected world, the Consortium was chartered with the objectives of also encouraging innovation in the Industrial Internet sector by utilising existing use cases, and creating new use cases and test beds, for real-world Industrial Internet applications and by delivering best practices, reference architectures, case studies and standards requirements to improve the ease of interoperable deployment of connected technologies in industry.

The IIC operates with global scope and openness to international membership, based on the Consortium’s recognition that in today’s global economy members need to collaborate with colleagues across the world to address the unique challenges of incorporating the digital with the physical.

 Globally integrated enterprises run factories and source parts and materials from across the globe. Smarter cities and governments across the world will utilise and benefit from the Industrial Internet, and this will likely enable smarter buildings, improvements in energy efficiency and smart energy management, better emergency communication and responsiveness.

 While much of the initial industrial support that founded the Consortium comes out of the United States, the scope of the IIC is worldwide.

IIC2

 The IIC views the technology industry at the precipice of a major technological shift, where smart machines will communicate and connect in ways that will lead to transformational business outcomes. Any company that wants to have a voice in setting the direction for the Industrial Internet is encouraged to join the Consortium. IIC members are developing critical collaborative relationships with leaders in technology, manufacturing, academia and the government on working committees.

 Members can participate in IIC research, test bed and standard-building activities, while members also gain an immediate, visible platform for their opinions. IIC members are encouraged to join one of several collaborative working committees: technology, architecture, or security working committees, for example.

 There are many different organisations working on industrial, academic and governmental coordination and cooperation in the development of standards and technologies for emerging Internet-of-Things and machine-to-machine applications.

All these organisations have similar, overlapping goals of delivering best practices, reference architectures, case studies, and standards requirements to make the deployment of connected technologies easier. While other organisations focus more on developing standards, the IIC has more of a focus towards creating frameworks, use cases and test beds for real-world applications across various industrial environments. You can learn more about the IIC by visiting their website

 As the consortium is founded by such strong organisations, it is sure to be another success in the world of the Internet of Things. And if you’re considering working in this field, our experienced award-winning engineering team can harness embedded hardware and software for your success in the IoT space.
