I'm having a problem getting the APM2 to work with the DJI ESCs and motors I just got.
I have the DJI 30amp 11.1V ESCs with the DJI 920KV motors. I have everything plugged in into the APM2 and when I plug the battery in all the ESCs/Motors give the abnormal input signal beeps and none of the LEDs turn on on the APM2. When I plug the APM2 into the computer via the USB (before I connect to the Mission Planner) and than plug in the battery I get the ready beeps. When I disconnect the USB (with the battery still plugged in) I get the abnormal input signal beeps again.
I know that the APM2 I have can work because I built a GAI 500x with the APM2 on it and it flew wonderfully.
UPDATE: I ran through the configuration in the Mission Planner and after I did that I was able to run the motors command in the CLI and it worked! I was even able to arm and throttle up the quad when it was plugged into both the computer and the battery. But I still get the abnormal input signal beeps and no APM2 lights with only the battery plugged in.
