I just installed Ver. 3.0.1, but when I power my Hexacopter (APM), I am only getting a single beep instead of two beeps before it goes into it's tune. The Mission Planner is not indicating an error, and I am able to arm the copter. Note: All motors respond correctly once armed. Also, my hexacopter firmware was 2.9.1b, and there were no problems.
Things completed before the problem.
I flashed my Ardupilot Mega 2.5+ and installed the Arducopter firmware 3.0.1.
Flash: All green lights and "Success" once installed
Arducopter 3.0.1: No errors - "Done"
Accelerometer Calibration: Successful
Live Calibration: Compass offset x = 1.6373, Y = 4.316 and Z = -26.002
Note: I haven't completed the Compassmot since I noticed the single beep when powering from the lipo battery.
I checked all of my connections and they look correct. - Need some help.
