Documentation for IDF v4.1.4 is available at https://docs.espressif.com/projects/esp-idf/en/v4.1.4/

ESP-IDF v4.1.4 is a bugfix update for ESP-IDF v4.1.3.

Obtaining v4.1.4

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 v4.1.4 --recursive https://github.com/espressif/esp-idf.git esp-idf-v4.1.4
cd esp-idf-v4.1.4/

This is the recommended way of obtaining v4.1.4 of ESP-IDF.

Major changes

This is the list of changes since release v4.1.3:

Major Bug Fixes

Changelog

Bluetooth

Controller

Fixed

  • Fixed that FreeRTOS semaphores and queues used by Bluetooth Controller are created in SPIRAM, which causes software crash when handling ISRs
