Many thanks for making this project and others open source.
Yes I've been using the files under the link you posted. And using the firmware for the esp8266/esp32.
I think the driver in Indi (myFocuserPro2) has not been designed/modified to reflect the changes you have made from the original 'myfocuserpro2' to 'myFP2ESP'.
Btw, can you show me where I can access this version of your linux application....
