Make Azure IoT Hub C SDK work on tiny devices!

Azure IoT Hub C SDK is written in ANSI C (C99), which makes it well-suited for a variety of platforms with small disk and memory footprint. We recommend at least 64KB of RAM, but the exact memory footprint depends on the protocol used, the number of connections opened, as well as the platform targeted. This blog walks through how to optimize the C SDK for constrained devices.

 

We release our C SDK as packages on apt-get, NuGet and MBED to accelerate the development process. However, if your system is constrained in ROM or RAM, you may want to build the SDK locally and remove certain features to shrink the footprint of the C SDK. We will be using cmake to demonstrate in this blog. In addition, the programming model for working with constrained devices is different. This blog will also discuss some best practices to reduce memory consumption. There is also official documentation on how to develop for constrained devices available to you.
