+In Rover mode, the output rate must be set to 5Hz.

 Note: NANO RTK Receiver and GEM1305 do not support safety switch, so BRD_SAFETY_DEFLT needs to be set to 0 or a separate safety switch should be connected to the flight controller.
 
 After completing the above settings, you can write parameters to the flight controller.
