how to point to older esp32 library

[tjodork]

in the arduino gui... i include the library
https://raw.githubusercontent.com/espre ... index.json

that is at V2.0.9

I'm getting unexpected errors and would like to point to V2.0.3 which I can scroll down and find at
https://github.com/espressif/arduino-esp32/releases

is there a way to point to that V2.0.3 library so I can compile with that level just to sanity check if issues are related to newer library ?
If I can't do that...if I download the zip file ...where would I put the files and what would i have to do?..

Thx

There are instructions for manual installation at https://docs.espressif.com/projects/ard ... lling.html.
The location for manual installs is <sketchbook_dir>/hardware/espressif/esp32. Using git will allow you to easily checkout whichever version you want to build against (you need to restart arduino after a checkout).
