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 may be build into firmware along with application code.
This library, currently a Beta release, will supersede both the AWS IoT Device SDK Embedded C and the libraries provided with Amazon FreeRTOS.
