I want to change pin number of Rx and Tx pin in modbus master example. I changed it in sdkconfig.h file and then after save it. but when i build my project, all changes are reversed or pin number became as it is before i make changes.
Ex. I changed my Rx pin GPIO 22 to GPIO 17 but when i build my project my Rxpin number changed automatically to 22.

Run 'idf,py menuconfig' (or your IDEs equivalent) and change it in the menu system instead.

It depends. What ESP-IDF are you using? Are you using a particular IDE?

Thank you for your help i got my answer in your previous post. I tried another time and find that sdkconfig and your solution work perfectly. Thank you so much.
