I connected a expresslrs EP2 receiver (happymodel) on UART2 of a CUAV V3 (fmuV3 hw). I have set the serial protocol to CRSF (23) in mission planner.
The first 4 channels (A, E, T, R) are received correctly. Channel 5 however only sees the minimum or the maximum PWM value (seen in the radio calibration screen of mission planner).
I also receive some telemetry on my TX from the receiver.
Is this a know bug that channels above 4 are not received/read correctly ? Or did I do something wrong ?
