Hello
My dilema is my Mavic Pro connects to the DJI Assistant 2 no problem but when i choose Calibrate all i get is please reboot aircraft which i have done many many times and problem still happens.
Please can anyone help me as im running the latest DJI firmware on a current HP laptop (x64) which is running windows 10.I have checked in Device Manager and i'm on the current driver.

Any ideas?

Regards
Andy

You can calibrate the IMU and Compass using the app on your phone/tablet...

To calibrate the VISION POSITIONING SYSTEM SENSORS in Assistant 2 (which I believe is your actual question) it is important that you turn on the drone first then connect to the computer. Don't connect then turn on. Also, reduce the display size of the screen in your lap top/pc settings - I found 720 works all the time for this calibration.

Andy, please try to restart the computer and the drone and connect the DJI Assistant 2 again, also, you can try to change another connecting cable. See if it helps.

Try another PC/laptop and ensure you are on the latest version of Assistant 2 - you can also try uninstalling and reinstalling the Assistant 2

I found a video which helped me: I restarted my computer in an advanced mode by holding down shift-key while pressing restart computer, chose adcanced options and then alternative #7 (....without signature blabla..). I also changed battery, then everything worked =)

As of today I also have the message "recommending" recalibration of the sensors on my Mavic Air. I have a Macbook Air & iMac 24". DJI Assistant fails to deliver a screen pattern at any resolution on neither machines. Conclusion: DJI Assistant is an absolute waste of time on the Mavic Air, even with the latest update you can collect flight logs, or calibrate sensors. It is only good for a firmware update. Even DJI Assistant is not needed. Suggest DJI change the Assistant app developer quickly, and to a rapid re-design. They seem to have got it all wrong for months now. Most importantly, I am not at all worried about the sensors. They appear to work totally normal with the re-calibration recommendation being prompted. If you are worried do a front-rear-ground sensor check at launch, simple check. Sensors on mine bird are working fine. My guess is a firmware update will eventually remove this silly message. If it a genuine sensor problem DJI better get their act together quickly or there will a lot of unhappy owners Mavic Air out there with this annoying message. I recently flew in Halong Bay Vietnam from a steel boat, the drone and sensors were perfect even with the sensor alert activate. There are occasions where you may have to land without sensors anyway, good pilots should not totally rely on sensors to get them out of trouble in a tight space.

I was having the same issue and nobody at DJI was able to help me. However, try setting your screen resolution to the lowest setting - in my case it was 1280X720. That did the trick.

I was also having trouble with my sensors not activating during the calibration process using DJ Assistant.  What fixed the issue for me was disconnecting my external monitor from my Mac laptop.  I then restarted DJ Assistant and it worked fine.  I hope this helps.
