Gordon Williams, the lead of Espruino, is working on a new version of the Espruino board with a tiny form factor, and his Kickstarter ends in only 4 days.
Three years ago, Sierra Wireless, IBM and Eurotech teamed up to create a Working Group that would help address Machine-to-Machine (M2M) and Internet of Things (IoT) market fragmentation by promoting the use of open source implementations and open standards.
It’s incredible how much our community has grown since then, and I thought I would put together the infographic below to make it more visual. Feel free to share it, and visit the Eclipse IoT portal to learn more about the initiative.
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.
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)
