I have problem when i try to setting up my APM1280 with Mission Planner.
When i load the FW 2.0.55 Quad, everytihing seems ok. until i try to set up my radio.I have no respond from any radio channel, and i have no response from the flight data either.
When i connect to my APM in the terminal, i get signal from my radio.
I power my boards by a external battery connected to the rc-pins.
Thankful for any help i can get, Thanks!
