ESP-IDF v5.3.1 is a bugfix release for ESP-IDF v5.3.

Obtaining v5.3.1

For full installation instructions, see the ESP-IDF Programming Guide.

The source files attached to this release will not work due to our use of git submodules. Use one of the following methods instead:

Using git

To get this release, use the following commands:

git clone -b v5.3.1 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.3.1
cd esp-idf-v5.3.1/

This is the recommended way of obtaining v5.3.1 of ESP-IDF.
