can someone please please tell me what's going on with this apparently wide spread error message, I like many others are grounded.

Can anyone tell me how to calibrate the P4P? tried several times and always with the same result, IMU 1 Error 22..... folllowed the video to the letter I am now trying to keep it in the fridge for 24 hours....

Hello R&L Aerial, please make sure you do the IMU calibration on a completely flat surface.
And please post a screenshot of the error message here.

DJI-Mindy,
I'm not R&L but I am also getting the same thing, tomorrow will be day 4 of owning the P4 Pro and I haven't even been able to fly it yet...what's going on with all of our Phantom 4 Pro's?

This is the error I am seeing after multiple attempts at IMU calibration. http://imgur.com/9yJNbk0

There are six steps to calibrate the IMU. Did you finish all of that?

Of course. It always ends the same way with the p4p upside down and the lights flashing red and errors on screen.

Could you please export the flight data and upload it to dropbox?
You can use the same method as for the Phantom 4.
Here is a video tutorial for reference:

Mindy,

I must agree with others. I have already got an agreement of European Support to send my P4P back for replacement and know of several other owners who got their approval also. So, I really think it's no use to ask for flight data: they will tell you nothing you don't know already. I fear the accelerometer or gyroscope is stuck somehow. More: my P4P makes different startup noises almost every time I start it up, going from a 'normal' sound to a loud 'wrenching' sound as if it is trying to unlock something inside.

After collecting the flight data, our engineers will help to find out what's going on with it.

Ok, You've got a point there.
Still, who will want to trust a P4P that has refused IMU calibration dozens of times, made strange noises starting up, has flight data on it from november 1, even if with some software hotfix it suddenly starts to calibrate normally ?

I have the same problem with IMU and error 22. It's really weird, I tried so much that I can't even reset it now to factory settings or set any firmware down or upgrade. It really sucks because I feel like an beta tester. Another problem is the new dji go app which isn't able to update firmware. Really annoying weekend.

I updated through DJI GO 4.

Btw.: Meanwhile i could sometimes start the Drone without successful calibration. I got a wind warning, though it was not windy at all. The drone swayed heavily.

I sent DJI my flight details. Now I suddenly get this message in the DJI Go app and an update was carried out. I just could fly without problems.
 
I will also try the IMU calibration later. The first attempt with warm device has not worked yet.



The German text means:
Incompatible firmware found. Incompatibility may occur between different modules and the device.

Is this confirmed to happen ONLY on NON PLUS models?  The built-in screen/software P4P+ version is fine, right?

So i did now the Firmware Update on a Windows Computer and it worked but still IMU problem. No Firmware Update working on MAC and Iphone 6 Plus or Ipad Pro. I Hope they will Update soon. I will now do a reset and try some old Firmware for doing the IMU Calibration...

Probably it found that the battery needed updating, if you put in another battery it willl do the same

Thank you for the data.
Our engineers had checked the data, it's probably a hardware issue.

I have a P4P+, IMU was stuck at point 4, no way to proceed to the next step.
Than I moved the drone not only left and right but to rear and than front using the some timing.
This enabled the app to go step 6 and I was able to complete the calibration.
Good luck
Clear app issue !

Hi fansd I will receive delivery of a P4P today and will sign for it somewhat reluctantly. Could you give detailed instructions on how you achieved a successful IMU? Regards.

If you do not have IMU issues do not calibrate the IMU, wait till next firmware release.

Hi Mauro, I sent a reply to your post a few minutes ago but it seems to have disappeared. Let's see if this one does! I am expecting delivery today of my P4P and I am not looking forward to signing for it given the number of problems owners appear to be having. Could you help further by giving a detailed account of the steps you took?

Thanks,

John

I see my post is back again. Don't know what happened there! I certainly do not intend an IMU calibration unless there is there is an issue and even then I am not sure I will want to.

If I were you I would send it back, my p4 pro has IMU error 22, loud fan noise and vibrating, on start up the camera slams up against the gimbal then slams into the bottom before coming to rest in the middle and the one time I managed to get it in the air it rotated in a circle with no stick input? I have initiated a return.

So this Error -22 is a battery problem caused by the P4P being upside down during the IMU calibration?

A loose connection?  Interesting if true.

For some it works

OK - more conjecture. There are numerous reports of loud fan noise and vibration. In another thread someone bravely opened their P4P up to find that the fan is only secured on two corners, with an unsecured corner resting directly against the inner shell - hence the noise and vibration. Solved by sliding some foam under that corner to buffer it.

Could this vibration (from clearly a design fault which may be exaggerated for some units) be throwing the IMU calibration out?

Just putting it out there...

It's not a battery problem, and we need the data for further evaluation.
Just want to clarify, if you do not calibrate IMU, it flies properly, right?

My P4P arrived this afternoon from My Drones, Brisbane. Personally delivered by the owner. He gave me a briefing on the set up. I performed firmware up dates on the RC and the drone. There was no request for an IMU calibration so I will leave that well alone.

The only small issue - not a problem with the Phantom - was that I did the updates etc., on the floor in front of a set of speakers. The app told me to do a compass calibration of move elsewhere. All that seems to be working as it should.

The next test will be a flight. We are off to the beach tomorrow camping. Not only is the area within a national park which means no flying unless granted permission but there is a helipad just 300 metres away on the top of a hill.
