In the next few months, we will have an official release of the AWS Reference Integration repository which brings in the 202012.01-LTS libraries. In this release, we will carry the LTS libraries and remove legacy ones from main branch. The legacy libraries will continue to be accessible through the 202012.00 release, and AWS will continue to support Github issues on these libraries on a case by case basis. We also created 20210526_Archive tag for archiving old libraries with the latest changes in main, but it is neither an official release nor tested.
We're removing the following libraries under /libraries/c_sdk:
- Defender Client Library V3.0.3 under
/c_sdk/aws/defender. Migrate to AWS IoT Device Defender v1.1.0 under/libraries/device_defender_for_aws(update from v1.0.1 in 202012.00 release). - Shadow V2.2.3 under
/c_sdk/aws/shadow. Migrate to AWS IoT Device Shadow v1.0.2 under/libraries/device_shadow_for_aws(no change from 202012.00 release) - MQTT Client Library V2.3.1 under
/c_sdk/standard/mqtt. Migrate to coreMQTT v1.1.0 under/libraries/coreMQTT(no change from 202012.00 release). - HTTPS Client Library V1.2.0 under
/c_sdk/standard/https. Migrate to coreHTTP v2.0.0 under/libraries/coreHTTP(no change from 202012.00 release). - Serializer Library V1.1.2 under
/c_sdk/standard/serializer. All libraries included in the upcoming release no longer have dependencies on the serializer library. - Common Libraries V1.2.0 under
/c_sdk/standard/common. All libraries included in the upcoming release no longer have dependencies on the common libraries.
We're relocating BLE library from /libraries/c_sdk to /libraries and removing /libraries/c_sdk folder.
We're also removing Over the Air Update V1.2.1 under libraries/freertos_plus/aws/ota and adding the new AWS IoT Over-the-air Update v3.0.0 under /libraries/ota_for_aws in the upcoming release.
This repo uses Git Submodules to bring in dependent components.
Note: If you download the ZIP file provided by GitHub UI, you will not get the contents of the submodules. (The ZIP file is also not a valid git repository)
If using Windows, set core.symlinks to true since copying a directory with symlinks may cause hangups:
git config --global core.symlinks true
To clone using HTTPS:
git clone https://github.com/aws/amazon-freertos.git --recurse-submodules
Using SSH:
git clone git@github.com:aws/amazon-freertos.git --recurse-submodules
If you have downloaded the repo without using the --recurse-submodules argument, you need to run:
git submodule update --init --recursive

The demos that connect to AWS IoT report metrics to AWS about the operating system, and the MQTT client library used by sending a specially formatted string in the username field of the MQTT CONNECT packet. These metrics help AWS IoT improve security and provide better technical support. Providing these metrics is optional for users, and these can be disabled by updating the following configuration macros in the demos/include/aws_iot_metrics.h file:
#define AWS_IOT_METRICS_STRING NULL
#define AWS_IOT_METRICS_STRING_LENGTH 0U
The format of the username string with metrics is:
<Actual_Username>?SDK=<OS_Name>&Version=<OS_Version>MQTTLib=<MQTT_Library_name>@<MQTT_Library_version>
where
- Actual_Username is the actual username used for authentication (if a username/password is used for authentication).
- OS_Name is the Operating System the application is running on.
- OS_Version is the version number of the Operating System.
- MQTT_Library_name is the MQTT Client library being used.
- MQTT_Library_version is the version of the MQTT Client library being used.
