Today when I first turned on my DJI Phantom 4 Pro something saying "Calibrating Vision Sensors with DJI Assistant with pc or mac is recommended". What does this mean and why do I keep getting it? Also, I use the DJI branded USB cable but it won't connect to DJI Assistant 2. I tried redownloading it and getting a newer version but nothing is happening. The computer recognizes the drone but Assistant does not.

Wholesale USB data cables

Calibrating Vision Sensors would help to make a better use of obstacle avoidance and vision positioning system. If you can not connect the drone to the application, that might because that DJI Assistant 2's driver had not installed properly. Please try to download it on another computer and calibrate the Vision Positioning System.

Thank You,

I will try to download it onto another computer and try it again. I never thought that and that is a big help

This is a try. See will it work. Looking forward to your feedback.

I have the same problem with ( DJI Phantom 4 Pro something saying "Calibrating Vision Sensors with DJI Assistant with pc or mac is recommended")

DJI Phantom 4 Pro something saying "Calibrating Vision Sensors with DJI Assistant with pc or mac is recommended" Same problem with my phantom 4 pro +.
I have a new build of a windows system ( Ryzen 1700X CPU, ) running windows 10, I downloaded the dji assist 2 software. I get different calibration screens from thors video link, maybe due to his being a phantom 4 and not a 4 pro. I go through the process and everything but when it gets to about 80% complete it pops to a screen and says calibration failed 0RO1.023864. Tried it with different screen resolutions from 4k to HD. on my 4k monitor. Called DJI tech support 3 times, no help, I'm Frustrated now.

Dear Aerial505,

Have you resolved your "Calibrating Vision Sensors" issue on your DJI Phantom 4 Pro

Dear Aerial505,

Yes, Try a different computer or monitor. Does not work well with win 10 4k monitor, I had success with an old laptop running win 7.
