I'm doing a project where esp32's, I need to downgrade the board manager to a lower version, I wish to download version 1.0.6, but I'm not able to get the right/correct version for the ESP32 board. If anyone knows do help.
The additional board URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json.
In board manager, versions from 1.0.0 are available for you to install.
