Hello! Thz for the reply. But in my case I'm not using pixhawk with ardupilot autopilot firmware, I'm using pixhawk with PX4 autopilot firmware. So, that's my big problem, I can't configure and don't know how to configure parameters in PX4 firmware for dragonlink V3. If you konw, please help me and I'm really love to get help from you.
Thanks you very much.
