Documentation and API References:

The AWS IoT Device SDK for C is a collection of C99 source files that allow applications to securely connect to the AWS IoT platform. It includes an MQTT 3.1.1 client, as well as libraries specific to AWS IoT, such as Thing Shadows. It is distributed in source form and can be built into firmware along with application code.

The CSDK v4_beta_deprecated branch contains a beta version of the AWS IoT Embedded C SDK libraries, which has now been deprecated. The libraries in this branch will not be released in their current form, and they are being refactored for resource constrained devices. For more information, view the readme at https://github.com/aws/aws-iot-device-sdk-embedded-C/tree/v4_beta_deprecated.
