When you prototype IoT solutions, it becomes necessary very early in your development phase to use an actual embedded platform to run your software, and to test it in an environment that is as close as possible of what you expect your production environment to be.
As I’m sure you know, there are lots of hardware prototyping platforms out there. In this article you will learn about three very popular options (from the cheapest/tiniest to the most capable) that can help you get started with Eclipse IoT projects in no time, and get pointers to useful docs and tutorials to make the initial setup as simple as possible!

What I really like with MQTT and CoAP is that they both are very simple protocols. When dealing with MQTT, the client itself has almost no state to maintain (at least when you stick to QoS 0 communications) and granted that you have an MQTT packet serializer/unserializer, it’s very simple to stuff such MQTT packets into TCP sockets using the networking APIs that your IoT microcontroller is providing.
I’ve had the opportunity to play with the TI CC3200 LaunchPad platform recently, and thought it would be a good candidate to try out the Paho embedded C Client.
The tutorial below, split into two parts (publishing and subscribing), gives a complete overview on how you can very easily port MQTT to the CC3200 and should probably be useful if you’re targeting another kind of platform, as it walks you through the process of tying in with the networking API of the underlying platform (TI SimpleLink™ in CC3200’s case)
Last year, EclipseCon Europe was the moment when the Eclipse Foundation, together with Eurotech, IBM and Sierra Wireless announced the creation of the M2M Industry Working Group.
Over the last 12 months, a great deal of stuff has happened: there are now three projects living under the umbrella of the Working Group: Koneki delivers tools for simplifying M2M development, Paho provides several client libraries and tools for the MQTT protocol, and Mihini plans on doing the first contribution for an embedded development framework in the upcoming months.
Recent news also include the creation of an M2M portal at m2m.eclipse.org that aims at being a window on all the M2M technologies being developed at Eclipse.
Therefore it is no surprise that there will be several interesting talks about M2M into the program of EclipseCon Europe, starting in just 2 weeks:
- M2M is a fairly new domain, and it can be complex to understand the scenarios it addresses. Bosch Software Innovations will give an overview of these scenarios, and how OSGi can be leveraged for simplifying M2M development ;
- The MQTT everywhere talk will not only be a deep dive into the MQTT protocol and show you how easy it is to use, but will also showcase different targets, from Java to PHP to tiny microcontrollers such as Arduino ;
- I am a huge fan of Open Source Hardware, and I am really looking forward to Simon Maple’s talk illustrating how the Raspberry Pi and Tinker Forge components can be used for creating MQTT-based solutions ;
- If you want to learn more about the 3 projects coordinated by the M2MIWG, and especially why Lua is a language of choice for developing M2M applications, you should definitely join Using Eclipse and Lua for the Internet of Things with projects Koneki, Mihini and Paho.
Ha, and of course I am very excited by the Flight Club (hat tip to Wayne :-)) contest, which showcase what may be one of the coolest M2M use cases: remote control of a freakin’ drone!
