I am getting an IMU attitude error on my screen whenever I handheld my Mini. This does not happen with my Mavic Pro so I am a bit concerned. I tried refreshing the firmware but It always fails. It is taking forever to refresh the firmware even if I have good internet connection.

Forgot to mention that I've already recalibrated IMU,Compass, Gimbal several times but IMU attitude error still persist.

Hi ChicagoPoy, we are sorry to hear about the difficulties that you encountered. Could you please provide a screenshot of the error prompt? We'd like to help you check it.

If it's just when you hold over 30 deg from level that's normal.

hi,

30deg when he is on or off?
when you put it in the case, its almost vertical, 90° deg, right??

thx

Doesn't matter when switched on or off. Only when taking off.

I always put mine on the ground or a flat surface when initially connecting, as soon as I pick it up to do a hand launch or move it I get errors.

As soon as I launch or put it back down the errors go away.

That's probably normal. If you pick it up, it's going to become unlevel and throw an IMU error until it get's leveled back out.

Hi Natalia, here's the screenshot. Hope you can have a look at this. If this is just normal when handheld, than good. But why are other Mini users don't get this error? Thank you

I'm a Mini user, I get that same error when I pick up my Mini.

Put your Mini on a flat surface, does the error go away?

Exactly what I said earlier and what fansef4ae8a7 just said. If you pick it up it will cause an IMU error. Does it give the error if it's just sitting level on a flat surface not being moved around?

Aha good to know that.

I see. No, error goes away when placed on flat surface. So this error is normal? Is it safe then to fly the Mini? Thanks

Yes, that is normal. The drone isn't expecting to be moving around before take off and that's what messes with the IMU. If that is the only issue you are seeing you should be good for flight. Just make sure to do your preflight checklist before lift off.

Hi, thank you for providing the screenshot, I'll confirm it with the related team. If there is an update, I'll let you know.

It's the same as above. It happens whenever I pick up the drone and move it. The error goes away as soon as I place it on a level surface. I assumed it's because I was carrying it upside down or on it's side or under my chin so I can open the door to get outside.

Understanding IMU for those who may not know .

IMU "Inertial measurement unit" .

As far as I see it, IMU calibration on a level surface updates a table of values the flight controller software uses as a reference for a level stationary hover. From there the craft responds predictably to flight commands.  It also likely measures any sensor noise and thermal drift so that these technical imperfections are accounted for when using IMU sensor data in flight. - this is likely why there must be no vibrations during the calibration process.


Bad IMU calibration could cause drift and attitude issues as the flight controller fights to hold the craft in what it thinks is the correct attitude as opposed to the correct physical attitude.


The IMU usually has 2 types of sensors – angle and acceleration and in turn 3 sensors of each type measuring in the X,Y and Z axis. These sensors can, through vibration, aging, impact etc, drift in their response over time and thus an IMU calibration will establish a new reference for the IMU’s level/stationary state that the flight controller can work with to restore stable flight.


Think of calibration as the bringing back into line the measured craft attitude with the true physical craft attitude.


Best way I can explain my thinking around IMU.

An example should make it clearer.
Imagine an X shaped quadcopter, if the desired tilt is horizontal to the ground and the nose of the quad tilts forward, the IMU will recognize this, the IMU will feed this error to the flight controller. The flight controller will send an instruction to the motors on the front of the quad to speed up and so lift the quad back to horizontal. As the error is being corrected the IMU is monitoring and registering the reducing error, the reduced error message is sent to the flight controller and the speed of the motors is adjusted accordingly until the quad is back at its desired tilt. Millions of these instructions are sent per second .

i think its normal ... same happens with me ... i think when you pick it up and it got little tilted .. so that why the error

It's not really an issue. The error only shows up when picking up the drone and moving it or just holding in any position other than flat.

It goes away immediately as soon as the drone is placed on a flat surface.

Hi there, thanks for your reply. Should there any further questions, please feel free to contact us.

Received this error for first time but this makes sense.

I don’t have an attitude! Well, I just have a personality you can’t handle.

I am facing no gps issue in my new Mini2 drone.
I even tried flying under clear sky ....free space...and update the firmware and safe mode ..also calibrated imu and aircraft....but still showing me no gps .
What is the issue...is this the faulty product I received in which gps device is not working.please suggest
