FreeRTOS AWS Reference Integrations

Cloning

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

Important branches to know

master --> Development is done continuously on this branch
release --> Fully tested released source code
release-candidate --> Preview of upcoming release
feature/* --> Alpha/beta of an upcoming feature

Getting Started

For more information on FreeRTOS, refer to the Getting Started section of FreeRTOS webpage.

For detailed documentation on FreeRTOS, refer to the FreeRTOS User Guide.

AWS Collection of Metrics

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

Format

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.
