Esp32c6 to Esp32c6 serial data transfer not working

I have tried setting up board to board communication using pins D6/D7 & ground and when that did work tried using pins D1/D3 with software serial. I don’t see any messages on the receiving board. Any guidance to make this work will be appreciated,

make sure you switch the pins, probably got it backwards in the code, try getting it working with a UART device or sensor first- lower baudrate… slow and steady wins the race

i use this device

Thank you. That was part of the problem. I resoldered all the connections and now using software serial D6/D7 as Tx /Rx on BOTH boards ( wires are crossed but pin definition is not reversed.
