Received my purple yesterday, just in time for Xmas ;) Connected it all to my quad and it all seems to work (radio input, sensors, xbee).
What I can't get to work right now is the arming of the ESCs. I can arm the APM and verified outputs 1-4 with a servo (raw/radio view shows 1-4 output going up when adding throttle). But because the ESCs do not arm the motors do not spin up.
When powering the system up the ESC play the short melody. This is normally followed by a beep for each cell and then a long beep. However this part does not happen right now. Once in a blue moon, ESC number 4 arms and spins.
I calibrated all 4 ESC manually and they arm properly when connected directly to the receiver. Also tried to calibrate them with a trim offset to make sure they take a higher signal as 0 throttle. The calibration through the APM does not seem to work. The light do the dance on the initial power-up. But the ESCs do not seem to get the high throttle signal on the second power-up.
Could it be that my ESCs do not like the signal from the APM? It worked with APM1, KK and multiwii...
For now I'm out of ideas. Any input is appreciated.
