When flashing a BlueROV2 (with standard pack) pixhawk firmware by connecting qgroundcontrol directly to the pixhawk Qgroundcontrol creates a ‘vehicle 12’. Afterwards when connecting the vehicle via the fathom s boards and the tether Qgroundcontrol connects to a ‘vehicle 1’. Is this normal, at times Qgroundcontrol seems to get confused over which vehicle to connect to as both vehicle 1 and 12 persist and at time . both seem to connect simultaneously. It seems to be causing issues for us - any ideas?
