To create a modified version of the firmware with custom pins, just follow these steps:

  1. Download the firmware following Espressif's guide.

  2. Download the at.py program from the tools folder in the ESPAT repo.

  3. Run the python command python at.py modify_bin -tx <tx pin> -rx <rx pin> -cts <cts pin> -rts <rts pin> -in <factory bin patch> --output <output bin patch>

  4. Send the generated binary to the board.

That's enough to have version 2.2.0.0 running on third-party boards based on the ESP8266 :)
