New problem.  Every time I start the aircraft and remote, I am getting the errors "downward vision sensor calibration error", "forward vision sersor calibration error" and "vision sersor communication error 10c00".  I have, thus far, been able to restart SEVERAL times and it has gone away and all works fine.  HELP

Hello, I'd suggest you to install the latest DJI Assistant 2 and calibrate the vision system via this software and PC. It would be better to clean the vision system before calibration:

I've had the same problems ever since I updated to the latest firmware. i don't know what to do.  I also noticed when I have these problems the firmware version says "unknown" yet when it randomly decides to work it tells me I'm running the current verison.

It is recommended to re-upgrade the firmware via DJI Assistant 2 again.

I had the same problem. After calibrating the vision sensors via the assistant 2 program I haven't experience yet. I'm on my 5th flight after to calibration. So far p good.

You are just looking at the Status page for the sensors.  In order to calibrate them you have to go into the Settings, IMU calibration is under Sensors.

I have the DJI Go app installed on my iPhone. I just noticed that the DJI Mavic and P4Pro require the DJI GO 4 app. Once I started using the DJI Go 4 application, the error no longer exists. Now, I wonder if the DJI Go 4 app supports my older P3 Advacned...hmmm, that's a whole new question.

DJI Go 4 does not support the P3 range. It's for P4, P4Pro, Mavic, Inspire2.

im also havn

im also having that same problem.... how to solve this... Forward and downward vision sensor calibration errors

I'm having this problem too, I'm also still getting a battery error. It keeps telling me to reconnect the battery. Because of the weather I hadn't really flown a lot, I'm just hoping all this would be cleared up before the weather clears up.

Calibrate the vison sensors using DJI Assistant 2 from Here (a good bookmark, lots of goodies).

This video can be used as a guide, latest Assistant 2 might look slightly different, but principles the same:--

Thanks. I guess I'll have to give it a try. I've never use the Assist app I just like to fly around and take pictures. When I first got it I never had any problems with it. Now every time I go to fly I have to update something.

thank you...

i am currently going through the same problem. it is telling me to calibrate the vision sensors. I have tried doing it and it tells me that it has failed and retry every time. I have downloaded the dji assistant 2 and the only thing on it is to update the firmware. there is NO option to calibrate the sensors. how can I fix this.

It should look something like this, click on the 'calibration' tab in the left hand menu:-

Mine doesn't show that stuff. I only have firmware and black box and those are the only two things on the left hand side. The only other thing that I can think of is that I needed to download again and it came up the same exact way the second time. So now I am thinking that it might be a problem with the programming of the mavic itself. I even reloaded the firmware to see if that might make a difference and it didn't.

maybe they don't have all of that stuff for the Mavic just yet?

So you download Assistant 2 (PC or Mac ?), and install it, accepting the USB driver pop-up when it appears on screen. Then re-launch Assistant 2, power up aircraft and connect to PC/Mac using USB cable. Click on device icon when it appears on Assistant 2 page, and that should be it.

As you say though, the procedure might be different or not in place yet on Assistant2 to calibrate the 'Sensors' on the Mavic. Or it could be a software/firmware glitch.

I first downloaded the zip file for PC. Windows based. After installation I started up the program, connected the mavic and the button for RC MAVIC PRO came up. I hit the button and then the next page that came up only had firmware and black box and nothing more. I am an IT person by trade. Cyber Security and all that.

Have a look at page 23 on the manual , downloadable from Here.

There is also an option to calibrate sensors on Mavic via DJI Go 4. (I wonder if Assistant 2 needs to be run as 'Admin' ?).

I tried the DJI Go 4 app several times, followed the instructions explicitly and it tells me every time that the calibration failed and need to RETRY. I have tried following the app, then I tried turning the drone at every corner, then the right way and to no avail. I will see if there are other ways to get into the program. I am only able to sign into it by email, and the options are extremely limited. Tonight is a new day right? lol. After work it's game on.

"Tonight is a new day right? lol. After work it's game on."

That sounds about right

Be sure to check sensor cameras for dust etc.

Try another USB lead as well, just in case.

I am going to also try deleting all of it, on the phone and the PC. Reinstall and start fresh.

new firmware update, definitely doing this when I get home.

Help me please. Once i've did calibration. May be i did it wrong, but my phantom start to ask me calibrate it. I start DJI Assistant 2 and button START is not active.

Sorry. I download Assistant for Phantom 4, not for pro. But i think they are similar

I dont know what happening, but I connect my phantom and do calibration operations. BUT... on 90% it freeze! Im waiting about hour and close the application. Try to start again and same problem. WTF?

WTF ?

Why The Failure ?

Presumably you're using the latest version of DJI Assistant 2(V1.0.9) to calibrate the sensors on your P4. It seems odd that it's accepted the calibration input (lining up the blue squares, and then sticking on the final calibrate bit. Is there another computer you could try it on ?

Aardvark Posted at 2017-2-19 10:06

I dont know why, but after restarting, rebooting etc my operation of calibration successfully done. BUT. In DJI GO still see that

If you're using a Phantom 4 try moving to DJI Go 4 and see what that reports. DJI Go 4 is the way forward for the 4's, Mavics & Inspire 2 etc.
I believe the Phantom 4 and the 4 Pro versions of Assistant 2 to be the same file, but there may be a chance there are differences between them.

I dont know why, but now i try to run phantom, and this message is gone

What interesting...
After some time i once more start phantom and rc and have no any messages in DJI GO. I don't know why it happening (
Thanks for help. Now everything is fine )

Hi, I'm having the same problem!!!
all happened after I did the last update.
started to appear the vision sensor calibration error.
I did everything and nothing work.
calibration with dji 2 assistant nothing showed on the screen only a blank screen.
so then I crashed when I'd test the mavic, nothing serious but it did not respond at all.

i couldn't get this to work.    .    . until i stopped trying on my imac and used a pc labtop. worked 1st time!

Did you update? Is your camera hanging freely?
