Hi Vincent, Thank you for your answer! I accept you aren't able to reproduce. I want to find something different between you and me. I answer your questions Can you come up with something an different?? >If you don't move the device for long time, the magnetic data will keep drift or just change to one value like without offset? Yes.(Please see following reprocedure data) >At the same time, do you see heading drift also? I checked an EUR_Heading data. answer is No.(it means no drift EUR_Heading data) >Please double check if you have big magnetic distortion around the sensor during sensor run time. I still confirm that this issue happen in stable magnetic field. --- I reproduce again --- IMU is not move in following procedure. 1.boot in AMG mode(not offset by fusion mode) x: -49.0 y: 45.0 z: 41.0 2.write program for NDoF mode and reboot.(still not offset by fusion mode) x: -49.0 y: 46.0 z: 42.0 3.give shock imu(offset by fusion mode) x: -29.0 y: 28.0 z: 25.0 4.about 15sec later(not offset by fusion mode) x: -48.0 y: 45.0 z: 41.0 5.keep this value continued for more than 5 minutes after that.
