AWS IoT Device SDK for Embedded C (C-SDK) version 202011.00 now includes refactored coreHTTP, AWS IoT Device Defender, and AWS IoT Jobs libraries alongside of the existing coreMQTT, coreJSON, and AWS IoT Device Shadow libraries. All libraries have been optimized for memory usage and modularity, and have undergone code quality checks (e.g. MISRA-C compliance, Coverity static analysis), and validation of memory safety with the C Bounded Model Checker (CBMC) automated reasoning tool. For more details, see the README and Changelog files.  

C-SDK is a collection of C source files under the MIT open source license that can be used in embedded applications to securely connect IoT devices to AWS IoT Core. It is distributed in source form and intended to be built into customer firmware along with application code, other libraries, and an underlying operating system (OS) suitable for constrained embedded devices.

You can get started by downloading source code from GitHub, and can find more information in the AWS IoT Core Developer Guide for C-SDK.
