IMPORTANT: Please choose the branch of this repo, based on the FreeRTOS-LTS release that you would like to base your application on.

If you are using the older (3.x.x) aws-iot-device-sdk-embedded-C release, please checkout the release/v3.1.x branch.

This SDK enables AWS IoT cloud connectivity with ESP32-based platforms using the libraries provided as a part of the AWS IoT Device Embedded C SDK.

• Please clone this branch of the repository using

  git clone -b "<name_of_the_release_branch>" --recursive https://github.com/espressif/esp-aws-iot
  

  For example: To clone just release/202210.01-LTS, you may run:

  git clone -b "release/202210.01-LTS" --recursive https://github.com/espressif/esp-aws-iot
  

• Please refer to https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html for setting up ESP-IDF
  • ESP-IDF can be downloaded from https://github.com/espressif/esp-idf/
  • This SDK supports release/v5.1, release/v5.0, release/v4.4 and release/v4.3 of ESP-IDF.
  • Please set your branch to the IDF release that you would like to use, and pull in the latest changes.

  Note: Please read Support Policy below for more details.

• Please refer to the example README for more information on setting up examples.
• For a production-ready starting point for making applications that connect to AWS IoT Core using esp-aws-iot, refer to the reference example.
• Please refer to the Security Guide for steps to enable Security Features on your Espressif chip.
  • This SDK supports multiple ways to securely store the PKI credentials.
  • The default method is to use PKI credentials which are embedded in the binary, using the certs from the certs/ in every example.
  • For using Secure Element (ATECC608A), you will need to use esp-cryptoauthlib.
  • The Security Guide includes detailed steps and pointers to configure and use the Digital Signature Peripheral on supported chips, using esp_secure_cert_mgr.
