I am trying to get telemetry from this new F4 board using Sport.
I had it working fine with ELRS 3, but I had to change the radio and I installed a R-xsr.
SBUS is attached to Sbus pad on the board and is working fine. I understand there is no inversion on this board, so I am using the uninverted pad from the receiver and soldered it on T3, which I assume is serial3. I tried changing every parameter possible with no luck…
Does anyone have any hint?
