My Mini4 Pro had a bad landing, now when aloft, the vision sensor error messages popup, including forward/reverse, Up/Down and left/right ones.  Eveything else seem functioning fine.

Is there something I can do, or check, or it needs to be sent away for service?
Thanks for the help.

cheers

Hello, Fred F. The aircraft will disable vision sensors when it is on the ground to reduce power consumption. When the aircraft takes off, all vision sensors will be enabled. Please feel free to use them.

Thanks.  The messages appear on taking off and in the air, like you said.

Something else to check?

Hi, there
Thanks for reaching out.
Please follow the steps below for troubleshooting:
1. Check whether the aircraft is in Sport mode.
1) If the aircraft is in Sport mode, the vision sensors are disabled by default, and obstacle avoidance is unavailable. Please fly with caution.
2) If the aircraft is not in Sport mode, please check whether APAS is enabled. The vision sensors will not operate when APAS is set to "Off" rather than Bypass or Brake.
2. Turn off the Vision Positioning and Obstacle Sensing.
3. Check whether the flight environment meets the operating conditions of the vision sensors. For example, the flight environment should not be too dark. For detailed conditions, please refer to the User Manual of Mini 4 Pro.
4. Check whether the vision sensors are blocked by foreign objects or a mounted third-party accessory. Remove the foreign matter or accessory, restart the aircraft, and try again.
5. Please calibrate the vision system.
Please keep us updated after trying, thanks.

Thank you for your reply.

Here are my responses to your questions.

1. Check whether the aircraft is in Sport mode.
1) If the aircraft is in Sport mode, the vision sensors are disabled by default, and obstacle avoidance is unavailable. Please fly with caution.


NO, the aircraft is in N mode, not S mode.

2) If the aircraft is not in Sport mode, please check whether APAS is enabled. The vision sensors will not operate when APAS is set to "Off" rather than Bypass or Brake.]

Yes, it is in BRAKE mode.

2. Turn off the Vision Positioning and Obstacle Sensing.

Vision Position and Obstacle is ON.

3. Check whether the flight environment meets the operating conditions of the vision sensors. For example, the flight environment should not be too dark. For detailed conditions, please refer to the User Manual of Mini 4 Pro.
It was in bright day light

4. Check whether the vision sensors are blocked by foreign objects or a mounted third-party accessory. Remove the foreign matter or accessory, restart the aircraft, and try again.

No, they are cleared. I also cleaned them, but it was no help.

5. Please calibrate the vision system.

Please advise how to do that?  Also please take note, once the aircraft started, without even taking off, the icon left side of the GNSS icon turns red already, upon tapping it, it shows

FWD and BKWD unavailable
LEFT/RIGHT unavailable
UP/DOWN unavailable
(Vision Sensors)


Please advise
