A few days ago, I tested the waypoint flight in the auto mode. Initially, the UAV flight trajectory is expected, but up to a specified height near 50M (visual), the UAV began to fly in other directions at a constant speed, until fly out of the 100M before landing. It’s too strange, and why?
Then I carefully checked the LOG, found the cause of the problem. In log only to see the MODE and ERR information, I found that the UAV did not enter the Auto model, because the GPS data cannot be used, the UAV is still in the stabilize mode.PS. Latitude and longitude in log,RCIN channel PWM value in log,
