"many of your channels, including RC1, remain at "failsafe value"  of 874, it's a if your receiver partialy recovered, but did not got them all. I would throw it away, what brand is is ?"

Pixhawk changed flight mode from AUTO to ALT HOLD during flight

Hi everyoneLast day I was performing an auto mission when Pixhawk changed suddenly from AUTO mode to ALT HOLD. No, I didn´t give any input to that and there was no failsafe activated to blame.Only thing I see at the log is RC error messages, but in auto mission this shouldnt be any problem.MAVlink communication between Pixhawk and a Raspberry was on use during the flight, don´t know if it can be related.Any help could be appreciated. I leave here bin file.Thanks in advance!See More

Battery is a 4S LiPo with a…See More
