1610089 Remoter Controller not Bound/still confirming binding statues

1a510380 Downward vision calibaration error. Auto calibration in progress

One solution from 2018, The issue is with DJIs Assistant 2 and the drivers not being digitally signed, so they don’t tell you that since there not signed they then don’t get installed. You have ro uninstall Ass2 then boot your computer into safe mode and disable driver signature enforcement, you then reinstall Ass 2 but this time it will actually install the proper drivers lol.

You can then calibrate your vision sensors as normal.

One solution: Disconnect gimbal PTZ, boot up without it connected.

Advanced Diagnostic Steps

Inspect the Downward Vision Sensor Module:

• Physical Damage: Examine the sensor module for any signs of physical damage, such as cracks, loose connections, or dislodged components.
• Connector Pins: Ensure that the connector pins are not bent or damaged. A bent pin can prevent proper communication between the sensor and the mainboard.
• Check the Flexible Flat Cable (FFC):
  • Cable Integrity: Inspect the FFC connecting the downward vision sensor to the mainboard for any signs of wear, tear, ог damage.
  • Proper Seating: Ensure that the FFC is properly seated in its connector. An improperly connected cable can lead to communication errors.
  • Test with a Known-Good Sensor Module:
    • Component Swap: If possible, replace the current downward vision sensor module with a known-good one to determine if the issue lies with the sensor itself.
    • Firmware Refresh:
      • Reinstallation: Use the DJI Fly app to reinstall or refresh the firmware. This can help resolve any software-related issues that might be causing the sensor errors.
      • Factory Reset:
      • Reset Settings: Perform a factory reset of the drone to ensure that all settings are returned to their default states. This can help eliminate any configuration issues that might be affecting sensor functionality.

Calibrate Mavic Pro Vision Sensor Using DJI Assistant 2

1. Install DJI Assistant 2 software on your computer or laptop.
2. Make sure your laptop and Mavic Pro batteries have a minimum of 50% charge but better if fully charged.
3. Carefully remove the propellers from your Mavic Pro.
4. Connect the Mavic Pro to your laptop computer using the USB cable.
5. Switch on the Mavic quadcopter and open the DJI Assistant 2 software.
6. The DJI Assistant software will recognize that the Mavic Pro is connected.
7. Select your Mavic Pro drone and click on “Calibration” on the left hand side.
8. The next window shows you the steps involved with calibrating the Mavic VPS.
9. Spend a moment and watch the steps involved with calibrating the Mavic Visions sensors.
10. Next, click on the “Start Calibration” on the bottom right hand side.
11. Point the forward facing Mavic Pro vision sensors towards the screen.
12. Now the green and red squares have to match so you may have to move the Mavic Pro forward towards the screen and back towards you to get them to match.
13. Once the Mavic is in the correct position, the corners of the square will turn blue.
14. You calibrate the vision sensors by moving the quadcopter so as to line up the corners of the blue square to coincide with the blue boxes.
15. Tilt and rotate the Mavic Pro following the blue square on screen.
16. Once this Phase 1 is complete, you will be prompted to move the aircraft away from the screen.
17. Next, you will have to follow the little squares around the screen again.
18. This will complete the Mavic Pro forward facing vision sensors.
19. The next steps is to calibrate the Mavic Pro downward facing vision sensors.
20. Point the under side of the Mavic Pro at the screen with the front of the Mavic pointing upwards.
21. Again, you need to have 4 blue corners so you may need to move the Mavic closer or further back from the screen.
22. Calibrate the bottom Mavic Pro vision sensors by matching the blue corners with the blue box following it around the screen.
23. Again, during this process you will be prompted to move the Mavic Pro away from the screen.
24. Then follow the blue square around the screen which is the last stage.
25. On completion of the Mavic vision sensor calibration, the DJI Assistant 2 software will automatically calculate, apply and save the VPS calibration settings.
26. When calibration is successful, it will show 100% and a message “Calibration Complete”.

Notes On Mavic Pro Vision Sensor Calibration

1. Insure that you have the latest Mavic Pro firmware before calibrating the vision sensors.
2. Only calibrate the Vision Sensors when the light is good and never calibrate near or over reflective surfaces.
3. Remove the propellers before starting the calibration.
4. It is best to have batteries full or as close to full on your laptop and Mavic Pro just in case the vision sensor calibration takes longer.
5. Give yourself plenty of space and have no interruptions while you calibrate the Mavic Pro vision sensors.
6. Calibration the Mavic Pro vision sensors require more or less only wrist movement to pivot, tilt and rotate the drone and following the blue squares on the screen.
7. Insure you fingers aren’t covering or close to the vision sensors while calibrating the Mavic Pro.
8. Leave the Mavic Pro on during the full process until you see the “Calibration Complete” message.

Mavic Pro Vision Sensor Quick Calibration Using Go 4 App

It is possible to do a quick calibration of the Mavic Pro vision sensors. This could be a quick fix if you receive the DJI Mavic vision system error while out aerial filming or if you feel the obstacle detection system isn’t working correctly.

If you don’t have a laptop with the DJI Assistant 2 app to do a full Mavic vision sensor calibration, then you can do a quick Mavic vision sensor calibration using the DJI Go 4 app.

To do the quick Mavic vision calibration, tap on the Aircraft Status in the DJI Go 4 app. Then click on Vision Sensors and start the quick calibration.

About The Forward And Downward Vision Sensors

Calibrate Mavic Pro Vision Sensor The Mavic Pro is equipped with a forward and a downward vision system which constantly scans for obstacles in front of it, allowing the Mavic Pro to avoid collision by going around, over or just hovering.

The forward vision sensor are on the front of the Mavic Pro, almost like eyes

e downward vision system use both ultrasonic and vision sensors along with image data to help the aircraft maintain its current position.

The main components of the Forward and Downward Vision System include 4 monocular sensors and 2 ultrasonic sensors.

The Mavic Pro visions sensors don’t work in S-Mode (Sports Mode) which is something to be mindful off.

In Failsafe Return-To-Home, the Mavic can avoid obstacles. However, you must remember that the Mavic cannot return to home or avoid obstacles if the GPS signal is weak, unavailable or if the lighting is insufficient.

Here is another terrific article which explains everything about collision avoidance sensors on drone.

Mavic Vision Sensor Light Signals

• 2 Green Flashes – In P-Mode with Forward and Downward Vision Systems working.
• Slow Yellow Flashing – No GPS. Also no Forward and Downward Vision System working.

Tips To Fix Vision System Error On Mavic Pro

The Mavic vision system error does not have to be coming from the vision sensors. It could in fact be caused by the ultrasonic sensors which are part of the whole Mavic Vision Positioning System. So the process of calibrating the vision sensors would not work if the problem is with the ultrasonic sensors.

If you’re quadcopter is only new and you are receiving the Mavic vision system error, it is important to troubleshoot the problem as quickly as possible. With new DJI products, there is always the option to return the quadcopter but this return period is not very long. However, don’t send it straight back without checking the below and following the below steps as it could be something very simple causing the Mavic vision system error.

Here are some instructions on what to try when you receive the DJI Mavic Vision system error.

1. If the Mavic is only new, check to make sure there is no tape or packaging covering either the forward and downward vision sensors.
2. Switch off the Mavic Pro, take the battery out and leave it off for about 2 minutes.
3. If the light is insufficient or flying over certain surfaces can cause the vision sensor system error. See below.
4. Ensure the vision sensors are clean. Use a soft cloth to remove any dust or debris from the sensors.
5. Check other parts of your Mavic Pro. If the quadcopter isn’t flying correctly because of bent or broken propellers, then incorrect information will be sent back to the flight controller, which could lead to the to the system error.
6. Check to make sure you are on the latest firmware and if not, then update immediately.
7. Calibrate the Mavic Pro vision sensors using DJI Assistant 2 software described above.
8. Try the DJI Go 4 Mavic quick calibration described above.
9. Check that you are getting a strong GPS signal in P-Mode.
10. Calibrate the Mavic compass. If the compass is not calibrated, the flight control system is not receiving correct information and this may effect the vision system.
