The OTA library enables you to manage the notification of a newly available update, download the update, and perform cryptographic verification of the firmware update. Using the library, you can logically separate firmware updates from the application running on your devices. The OTA library can share a network connection with the application, saving memory in resource-constrained devices. In addition, the OTA library lets you define application-specific logic for testing, committing, or rolling back a firmware update. The library supports different application protocols like Message Queuing Telemetry Transport (MQTT) and Hypertext Transfer Protocol (HTTP), and provides various configuration options you can fine-tune depending on network type and conditions. This library is distributed under the MIT Open Source License. This library has gone through code quality checks including verification that no function has a GNU Complexity score over 8.
Features
- This library has also undergone static code analysis from Coverity static analysis
- AWS IoT Over-the-air Update Library v3.3.0 source code is part of the FreeRTOS 202012.01 LTS release
- The AWS IoT Over-the-air Updates library exposes configuration macros that are required for building the library
- To provide custom values for the configuration macros, a custom config file named ota_config.h can be provided
- By default, a ota_config.h custom config is required to build the library
- To build unit tests, the submodule dependency of CMock is required
