when i fly my hex rotor a message displays on HUD of mission planner( EKF2 IMU 1 ground mag anomaly yaw realigned ) and follwed by another message (EKF2 IMU 0 IN FLIGHT YAW ALIGMENT COMPLETE) Kindly guide about this problem plz its urgent
Please post the .bin logs. Do you have any particular reason for sticking to EKF2 instead of EKF3?
I would start by checking if the orientation set in config is correct and recalibrating magnetometers.
