I have a companion computer connected to my copter which does upload and start the mission (the mission icludes a TAKEOFF event and at the end a LAND command).
The upload to the copter did went well.
Then the companion computer does arm the the copter and once armed sends the MAV_CMD_MISSION_START command over mavlink to the pixhawk.
However somehow the flight mode change to AUTO was denied by the copter but still the copter did takeoff in stabilize mode! luckily I regained control via the transmitter and was able to safely land the copter.
Can someone tell me what exactly happend why was flight mode 3 (AUTO) rejected? And why did the copter still took off???
PS: The same way I had flown mission over 50times already this was the first time it went wrong…
