ESP-IDF Release v5.0.3

Documentation for IDF v5.0.3 is available at https://docs.espressif.com/projects/esp-idf/en/v5.0.3/

ESP-IDF v5.0.3 is a bugfix update for ESP-IDF v5.0.

Obtaining v5.0.3

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 v5.0.3 --recursive https://github.com/espressif/esp-idf.git esp-idf-v5.0.3
cd esp-idf-v5.0.3/

This is the recommended way of obtaining v5.0.3 of ESP-IDF.
