ESP-IDF v4.4.5 is a bugfix update for ESP-IDF v4.4.

Obtaining v4.4.5

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 v4.4.5 --recursive https://github.com/espressif/esp-idf.git esp-idf-v4.4.5
cd esp-idf-v4.4.5/
