Ok I have a challenge that does not make any sense. I connect my APM 2.5 to the PC and start the mission planner and it claims they are connected BUT I am getting zero readings off the quad with the data or config tabs. No GPS no compass, no radio controls yet if I go into the terminal settings and test the gps or compass it reads it just fine.
It allowed me to download and install 2.9.1b but still nothing. On Top of that all of my motors are beeping like they are not calibrated.
First I thought it was a radio connection but the board will allow me to arm with the controller.
This is very frustrating any help would be awesome.
