I have a two quick flash LED that stays on even after all the pre arm checks are complete and the throttle is armed with the rudder.
I can find no obvious source of the problem because everything seems to be working as it should. I have:
Obtained 3d gps fix with hdop ~2
Checked mag compass operation and accuracy
checked airspeed indicator
run preflight calibration prior to arming
Tested failsafe (works on ground as it should)
Connected over Mavlink (works fine)
Essentially, I have run out of known tests to try, as the system seems to be working fine with everything up and running and a successful motor arm and throttle response. The way I understand it, if you enable all of the preflight checks to execute prior to arming, any one of these should prevent a motor arm-but I am able to arm fine every time. So any ideas as to what could be causing the red LED flash (2 quick flashes followed by a brief pause, then repeats)?
I can provide logs when I get back home.
