As I have different problems after upgrading to the latest version (output from esp_get_idf_version() ) v3.2-dev-39-gaff12390
I would like to install old version v3.1-dev-662-gf586f5e5 , but as I have not been able to find any information on how to install older versions, I hope some knows how to do it ?

FYI - the issues I have with the new version, is related to memory usage (I can not use same array size) and wifi (get to many event for the same event id (seems to loop) and problems with reconnect) - I did NOT have any of these issues with the old version, thats why I want to reinstall the old version

Thx in advance for your support.

The part after "g" in "v3.1-dev-662-gf586f5e5" is the short git commit ID. You can use it along with "git checkout" command. Don't forget to update the submodules.

git checkout f586f5e5
git submodule update

Thanks, I will try figure out where to add and/or change the below commands, so I get the correct version

sudo usermod -a -G dialout $USER && \
sudo apt-get install git && \
wget https://bootstrap.pypa.io/get-pip.py && \
sudo python get-pip.py && \
sudo pip install pyserial && \
mkdir -p ~/Arduino/hardware/espressif && \
cd ~/Arduino/hardware/espressif && \
git clone https://github.com/espressif/arduino-esp32.git esp32 && \
cd esp32 && \
git submodule update --init --recursive && \
cd tools && \
python2 get.py

I am new to all the Git stuff, but I am running Linux and when I run the command "git checkout f586f5e5" it does not find f586f5e5 , so there must be something missing or I am doing it wrong, so hope someone can list the command I should use to install the commit id f586f5e5 in Arduino ide when running Linux ?

Thansk again for any support you can give me

Howdy,
This may be a complete red-herring ... but I wanted to check that you understand the distinction between releases and master. As I understand it, the "master" on Github is the continually evolving "best so far" of the ESP-IDF code base. Things may break and stability may not be perfect. Releases are points in time snapshots of the master code base where (I presume) extensive testing has been performed and we can all agree on its content. If we visit the ESP-IDF GitHub page and look at the "branches" we see the releases available. These include "release/v3.0" and "release/v3.1" ... as well as "master".

Might you want to stick with a release version?

If so the recipe would be:

$ git clone https://github.com/espressif/esp-idf.git
$ cd esp-idf
$ git checkout "release/v3.1"

This would then mean you are using that specific version.

I also note that despite the "tag" "release/v3.1", the latest stable release is "v3.0.3" so I would go with "release/v3.0".

In addition, you can download the whole release from the Github releases pages as a ZIP file which might be an alternative story for you.

Thanks Kolban, I am still learning

When I look at "https://github.com/espressif/arduino-esp32" there is only one (1) Branch, the "master" , so not sure I can use your suggestion, but I will give it a try later.

I am moving from using from Arduino to Clion using esp-idf - but still have one large project which is not moved and that the one giving me these problems after I reinstalled Arduino and ESP32 on Linux.

I just found that I still have the old 'version' (Arduino & esp32) install on an old windows pc, so I might have to use that for this project until I got the time to move it.
