is there a way to connect my Laptop to the pixhawk and run it as a CC with the 3DR radio modules? the forum said i need to use a raspberry pi to bridge the FC and my laptop as CC. but i was worried that Raspberri Pi’s WiFi will interfere with my FrSky rx on board! and there is already too many components on board.
generally companion computer is on the vehicle and a laptop on a rover, boat or even worst a drone is not feasible.
I think u are looking for a Ground Control Station (GCS) and simply you need to have a telemetry module on vehicle connected to FC via telemetry port and a telemetry module connected to your laptop:
