Mixing Dshot and normal PWM operation for outputs is restricted into groups, ie. enabling Dshot for an output in a group requires that ALL outputs in that group be configured and used as Dshot, rather than PWM outputs. If servo and motor are mixed in same group, make sure this group run lowest PWM frequency according to the servo specification. ie. Servo supports Max. 50Hz, ESC must run at 50Hz in this group.

*** If connecting just one GPS to UART4(TX4/RX4), pls set SERIAL3_PROTOCOL = -1 or non “5”. otherwise ArduPilot will stop searching for GPS during bootup if not found on the first port(SERIAL3/UART5) configured for GPS protocol.

RC7_OPTION 28 //Use CH7 of Transmitter to control Vbat output ON/OFF
RELAY2_FUNCTION 1
RELAY_PIN2 82 //PIO2 pad
RC8_OPTION 34 //Use CH8 of Transmitter to control PIO2 Low/High Level
The configured feature will be triggered when the auxiliary switch’s pwm value becomes higher than 1800. It will be deactivated when the value falls below 1200.
Check the pwm value sent from the transmitter when the switch is high and low using the Mission Planner’s Initial Setup >> Mandatory Hardware >> Radio Calibration screen. If it does not climb higher than 1800 or lower than 1200, it is best to adjust the servo end points in the transmitter.
