Pixhawk 4 mini Servo actuation

I am currently working on a project creating an autonomous glider. As of now, we have communication between mission planner and pixhawk 4 mini via holybro telemetry radio.

The problem I am facing now is that I cannot for the life of me actuate the servo using mission planner. I’ve seen videos online where people change SERVO10_FUNCTION to 0 and set flight plan, setting waypoints and setting DO_SET_SERVO to ‘10’ and going into flight data -> servo and toggle them to command the servos, but I cannot do the same. I’d like some advice on this issue, as I have been stuck on the same matter for the past couple days.

Thank you :smiley:

What exactly do you mean by 'actuate the servo by mission planner,?
Do you have an rc input from a transmitter? If so are you able to control the servos in manual mode by usung the transmitter?
