Vision positioning sys off + 4.16 iOS MSDK virtual sticks issue

Disabling the DJI M300 RTK visual positioning system causes erratic aircraft behavior when the aircraft is taken over via virtual sticks, the aircraft should be hovering but it rocks back and forth with no command going to the aircraft. Can you please assist with this?

    Video has been uploaded. 

    The video demonstrates the aircraft (M300) performing the rocking back and forth when no input is provided via the virtual sticks. The expected behavior is to have the aircraft just hover in place.

    DJI team, 

    We are still experiencing flight behavior issues with the M300 and 4.16.1 iOS MSDK with the latest firmware. 

    We have verified advanced virtual sticks are being used and always have been.
     
    When the following properties are set on the DJI Pilot app the drone flies stable with no issue. When we set the properties through the MSDK, the unstable flight behavior continues. We tested setting these values while on the ground and in the air.
    flightAssistant.setPrecisionLandingEnabled
     
    flightAssistant.setLandingProtectionEnabled
     
    The drone is not controlable, when these settings are not enabled.

    Hi Gerardo,

    Have you ever tested with our official iOS Sample?

    We would like you to provide us with the flight control logs to help us analyse them. You can read the documentation in the link to find out how to export the flight control logs and then upload the logs to the link. Also, we asked some of our colleagues what this behaviour was generally related to and they replied that it was related to the status of the IMU, so you could keep an eye on the HMS(DeviceHealthInformation )for error messages and the status of the IMU. link:https://pan-sec.djicorp.com/s/e7AgCTKoZ4wLqE8 password:dji123

    We cannot find a valid flight controller log. It only contains one record and we cannot find any fly status in 2022.4.25 22：08 for time zone 0.
