Hi @andrewjamez -
You should NOT need to bridge that pad for SBUS to function! Here are the recommended steps:
- Flash Rover Beta (>=4.4) (assuming you’re trying to use a RC transmitter with a Blue Boat?)
- Make sure there’s nothing connected to Serial1
- Set SERIAL1_PROTOCOL to RCIN
- set RC_OPTIONS to 36
- Restart the autopilot
You should then be able to calibrate and use your RC transmitter from QGround Control Vehicle Setup menu.
