3 hardware platforms of choice to get started with Eclipse IoT

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!

Remote management of an ARM mbed device using LwM2M, Wakaama & Leshan

One of the great strengths of LightweightM2M (LwM2M) is to be… ahem… lightweight! The fact that it relies on CoAP for the communication, and that all the standard resources are meant to be very concise really helps making very small implementations that can fit in constrained devices.

In the video below, you can see how Eclipse Wakaama (a C implementation of LwM2M) has been ported to an mbed NXP LPC1768 – a device with just 32KB of RAM! – and is controlled from Eclipse Leshan, a LwM2M server in Java.

What I really like in this video is that it shows how simple yet powerful LwM2M actually is, and how efficiently you can fit advanced features like firmware upgrade in very constrained devices.
