Imu dji error

“IMU initializing do not move aircraft until initialization is over” “ has been an issue on DJI drones especially on the older models such as phantom 3 but can happen on the newer too, nonetheless, DJI doesn’t seem to come up with a solution.

It is not a serious issue, however, sometimes it will stay long to the point where it starts to annoy you. on top of that, the software won’t even allow you to lift off until the “initialization is over” which can sometimes take an hour for some reason and can sometimes even fail initializing imu.

The thing is, it is fairly easy to fix, but I see people demotivated from using their drones because they were not able to find a solution to this.

So what is causing this issue?

“IMU initializing…” is a common issue in old model DJI drones such as the Phantom 3 but can happen on any DJI drone. This issue is usually caused by the drop in ambient temperature that affects the barometer. this problem can be fixed by factory resetting the drone and recalibrating the in a low-temperature environment.

There are few ways you can use to fix this issue, let us start by recalibrating the IMU.

1. IMU caibration

Before doing this process you can turn your house’s ac to go below room temperature, Get the AirCraft (A/C) as cold as possible, you can even place it in a refrigerator, and then recalibrate the IMU.

The colder you can get it, the sooner you can get the process started after removing it from the cold area.

You can also do this process at night outside of your house where the temperature is colder, then when you want to fly your drone at day time it wouldn’t take as much time to initialize IMU.

1. First, startup Aircraft & Controller
2. From DJI go 4 app go to Menu on the top right
3. Go to Aircraft button (in the menu the uppermost button)
4. Then go to Advanced Settings then Sensors State
5. “IMU Calibration”
6. When done (can take UP TO 10mins!) -> “Check IMU”

2. Refresh firmware in DJI assistant 2

You should also do the classic troubleshooting methods staring of with refreshing the firmware

1. Power on the drone
2. Connect it to your computer using the USB cable DJI provides
3. Open the DJI Assistant 2 software on your laptop
4. Log in to the DJI Assistant 2 app and select your drone
5. Next, you will see the firmware version
6. Tap update and choose the latest version
7. If it is already the latest version click refresh
8. Repeat process with other batteries(if you own one)

Update/refresh Controller Firmware

The Drone’s and the controller’s firmware must match so after refreshing or updating your drone’s firmware you should do the same for the controller.

So, to update/refresh your RC’s firmware-

1. Power on the remote controller
2. Connect it to your computer using a USB cable provided
3. Open and log into the DJI Assistant 2 software on your laptop
4. Select your drone’s remote controller
5. Next, you will see the firmware version
6. Tap update if you have an older version or tap refresh if it is up to date
7. Click on “Start Update”
8. On the next screen, you will see the firmware being downloaded, then transmitted and updating the remote controller
9. At 100%, you will see the message, “Update Complete”
10. After the firmware is complete, the controller will restart automatically

3. Downgrade firmware

If both of the previous methods dont seem to work, you can downgrade the firmware till the next update comes out.

You can downgrade your firmware both in DJI assistant and DJI go 4.

To downgrade firmware in DJI assistant–

1. Power on the drone
2. Connect it to your computer using the USB cable
3. Open the DJI Assistant 2 software on your laptop
4. Log in to the DJI Assistant 2 app and select your drone
5. Next, you will see the firmware version and older versions lined up
6. Choose the version one below the current version you have
7. Then click install
8. Then the drone will automatically restart

To downgrade firmware in DJI go 4

press and hold the menu icon (three horizontal lines in the top right corner) for five seconds and a special firmware menu appears. You can now select which previous firmware version you would like to downgrade to. Check it out.

It is better if you downgrade with DJI go 4 because the controller will follow automatically.

If you downgrade in DJI assistant you most likely have to do the same with the controller

4. Factory reset

1. First, Install the DJI Assistant 2 Program on your device, make sure you download the proper one.
2. Connect your drone to your laptop using the USB cable provided, and wait for the software till it to detect your drone
3. You’ll be able to see your drone on the Connected Devices screen. Select your drone and then click on confirm.
4. Click on Firmware Update. After that, you’ll be able to see the “Restore factory defaults” button.
5. Click on the factory reset button and then confirm when you are asked to confirm the reset. A progress bar will pop up showing the progress of the reset. You’ll be notified when the reset is complete.

Note: After a factory reset you have to calibrate everything again.

Final choice

If none of the methods fix it you there might be a problem with one internal component and you might to send it to a professional.

If your drone is within a year period from activation, which I would guess is not because this error usually happens on older drones, however, if it is or if you have DJI care DJI will fix it for you for free

If not you might have to pay a good sum of money depending on the situation

After you hand it to DJI it can take up to 15 days till they fix it and send it back to you, and it can take longer if you don’t live in the united states

If you are located in Armenia, you may contact the local dealer or DJI’s support via email to start a case and send the unit back.

2 Ways to Fix Gimbal IMU Data Error (40021)

*In this article I will show you how you can fix “Gimbal IMU Data Error” however be a little complicated if you are not a techie person, but it can save you a lot of money and it is the only thing that will help you with this unless you send it to DJI, so stick on*

So, I crashed my Mavic mini a few weeks ago and the gimbal got damaged, then I bought a genuine replacement from Alibaba and replaced it.

Then when I was about to fly it I get this error “Gimbal IMU data error”.

After contacting DJI support, hours of frustration, and trying different things I finally fixed it and saved myself hundreds of bucks and so I thought I could do the same for others

First, if you don’t know what IMU is, it is a device that measures and reports the specific gravity and angular rate of an object to which it is attached.

Apparently, every gimbal has its own ID

And the id should match the rest of the drone’s components

So if the gimbal gets damaged you can’t change it without causing an issue.

The same happens if you replace the motherboard without the gimbal.

In other words, the IMU module data will have a hard time re-pairing with the new gimbal/camera you changed. That’s because DJI locks down their gimbals (and other components). so you can physically replace the gimbal, but it requires “activation” from the factory.

Apparently, DJI has special software called Repairtool that is used to pair the Camera ID with IMU, but it is not available to the public.

It took me ages to understand this, and when contacted DJI support team they said “contact our DJI Support Team to start up a ticket for us to diagnose the cause of the issue and a proper resolution will be provided“

And then they are going to charge me hundreds of dollars for a software problem, and so I said “no sir”

NOTE: in some cases, this error can be caused by an abstraction of the gimbal, in that case you need a professional.

First method

What I am about to show you is how you can calibrate your gimbal so you can get rid of the error and fly without any problem, however, it is impossible to pair the gimbal with the drone unless you send it to DJI.

1. Download dji Assistant 2, python for windows, python pyserial and pyserial-3.5.tar
2. Extract pyserial and DJI tools to a folder C:/DJI/
3. Open “command prompt” as administrator then leave it open
4. Connect your drone to your computer with the provided cable
5. The SERIAL PORT COM will come for 15 seconds and will disappear from Device Manager
6. So, as soon as it appears in Device Manager, Launch Assistant 2
7. The Mavic mini will appear in Assistant 2
8. It will automatically use the number of SERIAL PORT COM
9. (you can change the firmware if you want)
10. Close Assistant 2
11. finnaly type your command

Commands are (you can copy in order not to mistake, just place your serial port number)
python comm_og_service_tool.py com(your number, for example com3) SPARK GimbalCalib JointCoarse.

Second method- roll back to previous firmware

Firmware rollback or downgrade refers to the process of uploading older versions of the software that operates your drone.

Now what I am basically about to show is how to roll back the firmware and reset the gimbal. it can seem a bit complicated but it is easier than the previous method” if you can watch the video below where I will show you how I did it step by step.

If this method is too complicated, you can also downgrade the firmware in the DJI assistant 2 or go 4 app and try to calibrate the gimbal, the success rate is low because DJI updates the older versions too.

1- Go to drone-hacks.com
Go to your browser and type drone hacks and go to the first website, this website is handy to manipulate drone’s software, it is commonly used to Remove No-Fly-Zones, Altitude limits, and such kinds of things but it can also help to fix software problems like this

2- Download the software
There are three options to choose from: for mac, windows, and Linux. choose the one that is compatible with your computer and download it

There is no installation and no sign-up required.

3- Connect your drone to your pc
Just connect your drone to your pc with the provided cable.

The software will be able to recognize the drone. If not restart the drone and connect it again.

4- Click hacks/flash firmware tab
click hack/flash firmware under that tab you will find “download firmware” click it and it will automatically lead you to the download page.

1. Download firmware
   The software will automatically choose the latest firmware for you, however, we don’t want that so change it to V01.00.0302 that is the version that we are going to use to fix “Error Code 40011” after choosing that version go ahead and download it.

6- Install the firmware to the drone
Go to the folder where you downloaded the firmware and choose it and wait for 5-10 minutes then you are done! you can now close the software.

7- open dji go 4 app
The error will still be there, don’t worry yet!

Go to settings, under control, click center gimbal and your drone will calibrate it will take a minute or two, and hopefully the problem will be fixed.

Note: make sure your drone has a full battery before this process

*Note: before firmware update make sure all your drone, controller, and phones battery are fully charged because it can take up to 30 minutes*

Final choice

If none of this seems to work contact DJI support.

they have special software they will run on the drone that will automatically connect the gimbal with the motherboard which will fix the problem

if the drone is within a year period from activation or if you have DJI care you can get it fixed without any cost. If not you might have to pay from $99 up to $350.

After you hand it to DJI it can take up to 15 days till they fix it and send it back to you, and it can take longer if you don’t live in the united states

If you are located in Armenia, you may contact the local dealer or DJI’s support via email to start a case and send the unit back.

8 Ways to Fix Mavic Air’s IMU Calibration Stuck

People are having a hard time trying to calibrate mavic air’s IMU, they usually get stuck on step 2.

I also had this problem two days before I wrote this article, and I went on google but no one had a clear answer. Then I contacted DJI support but they couldn’t be more naive, anyways after reading a bunch of forums, hours of frustration, I finally solved mine so I thought I could do the same for others

Why is the imu calibration getting stuck?

if your IMU calibration is stuck try placing the drone under room temperature also reinstall DJI GO 4 and make sure you are following the steps properly.

There is no one single reason why this might be happening but the common reasons like not following the steps properly, for a successful IMU calibration, it is crucial that you follow the steps exactly as you see on the screen, or you will get stuck on one of the steps.

So in the next sections, I will show you how to properly calibrate your Mavic air.

1. proper calibration process

1. Place your drone on a flat/level surface

If you have an iPhone open your measure app or if you have an android download bubble level app and make sure you place your drone on a level surface

2. Put the drone arms folded with its belly

This step needs no explanation, put the drone in its normal position with arms folded.

3. Put the drone on its right side

Even though it is simple, step 2 is where people get usually get stuck.

What you basically have to do is face the drone’s belly facing to the wall, and its side facing to the ceiling.

However, even when you are doing everything correctly DJI go 4 app won’t proceed to the third step for some reason

So if this is happening look for the lights on the arm of the drone

When the green lights are flashing rapidly – it means it is calibrated for that position and it now wants you to move it to the next position.

So you don’t have to wait for the app, if the lights are flashing green just proceed to the next step!

4. Rotate the drone onto its left side.

Just repeat the previous step but on the left side.

5. Finally face the camera upwards

6. Put the drone belly up

2. Refresh the drone’s firmware in DJI assistant 2

If the calibration process is not working, chances are there is a software issue that is supposed to get fixed.

To do that I will show you a couple of ways

Let us start by refreshing the firmware

1. Power on the drone
2. Download the proper DJI assistant for mavic air 2 here and so on
3. Connect it to your computer using the USB cable DJI provides
4. Open the software on your laptop
5. Log in to the DJI Assistant 2 app and select your drone
6. Next, you will see the firmware version
7. Tap update and choose the latest version
8. If it is already the latest version click refresh
9. Repeat process with every battery you own

3. Downgrade firmware

If refreshing the current firmware doesn’t seem to work, you can downgrade the firmware till the next update comes out.

You can downgrade your firmware both in DJI assistant and DJI go 4.

To downgrade firmware in DJI assistant–

1. Power on the drone
2. Connect it to your computer using the USB cable
3. Open the DJI Assistant 2 software on your laptop
4. Log in to the DJI Assistant 2 app and select your drone
5. Next, you will see the firmware version and older versions lined up
6. Choose the version one below the current version you have
7. Then click install
8. Then the drone will automatically restart

To downgrade firmware in DJI go 4

Press and hold the menu icon (three horizontal lines in the top right corner) for five seconds and a special firmware menu appears. You can now select which previous firmware version you would like to downgrade to. Check it out.

4. Reinstall DJI Go 4

One of the troubleshooting methods DJI support recommended me is to reinstall the DJI go app and that is what helped me to solve the issue.

However there is one key thing they didn’t tell me and that is to restart my iPhone after deleting the app from my phone, I got that info from a forum. so anyways follow these steps.

1. Remove the DJI GO app from your phone
2. Restart your iPhone
3. Reinstall DJI GO app from app store/play store
4. Finally restart your phone and try connecting them again

5. Clear cache

If you have previously connected the drone and the controller and you already have a flight history you may have stored cache, and sometimes logged chance can cause problems

To clear the cache go to DJI Go 4 app, click on the settings three dots, and under “General Settings” you can see the video cache settings. You can select to “Clear Video Cache” here and free up a lot more space on your device.

If none of the methods above work for you, your last option is to factory reset your drone.

6. Factory reset

1. First, Install the DJI Assistant 2 Program on your device, make sure you download the proper one.
2. Connect your drone to your laptop using the USB cable provided, and wait for the software till it to detect your drone
3. You’ll be able to see your drone on the Connected Devices screen. Select your drone and then click on confirm.
4. Click on Firmware Update. After that, you’ll be able to see the “Restore factory defaults” button.
5. Click on the factory reset button and then confirm when you are asked to confirm the reset. A progress bar will pop up showing the progress of the reset. You’ll be notified when the reset is complete.

Note: After a factory reset you have to calibrate everything again.

7. Use a different phone

If you are using android to calibrate the IMU and it is not working try swapping it with ios, and vice versa.

8. Change location

I am not sure why but DJI recommends doing IMU calibration on an open field, so if you are doing the imu calibration in a tightly enclosed space go out and try it again.

Can you fly your drone without IMU calibration?

IMU or inertial measurement unit’s job is to keep the aircraft stable while in flight.

If you don’t calibrate the imu, the drone will try to avoid obstacles by using its sensors however it will be hard to operate for the operator.

If you have seen a drone go forward or backward without getting a signal it is because the IMU needs calibration.

Some drones come with a calibrated IMU so if you are not getting a notification on your DJI go for app chances are you shouldn’t worry about it unless there is a red flashing light on the arms.

Even though there is no way to tell which is which if there are red flashing lights on the arm then that is a signal the imu or the compass needs calibration.

Any way let get to the process of calibrating the imu

Make sure you don’t miss any steps because that is how you get stuck

Final choice

If none of the methods fix it your drone might have some hardware problems and for that, you might have to send it to a professional

If your drone is within a year period from activation which is most likely the case because I assume the drone you are trying to calibrate is new you can get it fixed without any cost.

If not you might have to pay from fifty dollars up to hundreds of dollars depending on the situation

After you hand it to DJI it can take up to 15 days till they fix it and send it back to you, and it can take longer if you don’t live in the united states

If you are located in Armenia, you may contact the local dealer or DJI’s support via email to start a case and send the unit back.

It’s normal to get error codes and messages when using Phantom 4 and it’s better to get some knowledge about those things and how to fix those issues. I went through many DJI forums and collected several error codes and how to fix them.

Hope this article would help with solving your Phantom 4 Error codes. Below, There is the list of error codes I was able to collect from DJI forums.

Common DJI Phantom 4/ 4 Pro Error Codes.

• Error 1: DJI Phantom 4 Error Code 50 (IMU Error).
• Error 2: DJI Phantom 4 Battery Error.
• Error 3: DJI Phantom 4 ESC Status Error.
• Error 4: DJI Phantom 4 Compass Error (COMPASS-ERR).
• Error 5: DJI Phantom 4 GPS Error.
• Error 6: DJI Phantom 4 Camera Sensor Error.

Error 1: DJI Phantom 4 Error Code 50 (IMU Error).

Phantom 4 Error Code 50 is an IMU calibration error and many Phantom 4 users get this error because of performing the calibration process near metal structures while calibrating the IMU. Also outdated Phantom 4 firmware, and glitched firmware also could cause the issue.

Solutions.

• Update Phantom 4 firmware. Outdated firmware and firmware glitches can mess up the IMU calibration process. Therefore make sure to keep the firmware updated when you perform any calibration. Read How to Update DJI Phantom 4 firmware if you need to.
• Perform the IMU calibration process in a proper environment. When calibrating IMU you need to pay attention to the surroundings. For example, you should perform the process on a flat surface and should keep metal and electronics away from the aircraft. Also, you should perform the steps properly. Read the How to Calibrate IMU article for a detailed explanation of IMU calibration.
• Factory Reset Phantom 4. Download and install DJI Assistant 2 application to the PC. Connect Phantom 4 aircraft to the PC. Open the DJI Assistant 2 application and log in to your DJI account and choose Phantom 4. Then go to the “Firmware Updates” tab and click on “Factory Reset”.

Если у вас остались вопросы касательно ошибок и ремонта квадрокоптера Mavic Mini, задавайте их в комментариях. Также, если у вас есть свой опыт в ремонте и решения проблем, пожалуйста, делитесь своим опытом в комментариях ниже.

Бывает так, что при нормальных условиях горизонт «уплывает вбок». Смотрится это зачастую не только не красиво, но и не профессионально. Исключения составляют те случаи, когда это делается специально для создание более динамичных планов (например так можно сделать с камерами х5 или х7 на коптерах серии Inspire 2. Если для фото режима небольшая коррекция горизонта не снизит ощутимо качество изображения, то в видеосъемке каждый пиксель на счету. 

Не будем здесь рассматривать случаи, когда проблема вызвана падениями. В этом случае верный способ исправить — это обращение в сервис центр квадрокоптеров. 

Другое дело, когда подвес стоит не ровно на новом коптере или без видимых причин — здесь обычно помогает простая процедура калибровки, которую можно выполнить в домашних условиях. 

Калибровка подвесов DJI

Инструкция подходит для большинства коптеров DJI таких как Mavic Pro, Mavic Air, Mavic 2 Pro, Mavic 2 Zoom, Phantom 3, Phantom 4, Phantom 4 Pro/Plus, Spark.

Для простой калибровки необходимо включить коптер и пульт, подключить смартфон к пульту и запустить приложение DJI Go 4. 

Войдя в окно камеры нажмите в правом верхнем углу иконку «три точки». 

В открывшемся меню выберите пункт «подвес».

В меню подвес и нажмите «Сalibrate Gimbal».

Во время процедуры калибровки квадрокоптер должен стоять на ровной жесткой поверхности. Не берите в руки квадрокоптер и не допускайте тряски. 

Важно: После калибровки перезагрузите коптер. 

Если проблему не удалось устранить таким путем, возможно стоит обратить внимание на состояние акселерометра. Возможно у Вас были какие-то жесткие посадки или длительная транспортировка (поезда/самолеты и тп). Это могло сказаться на точности работы блока IMU. Даже если коптер не сообщает о проблеме с IMU — все равно стоит его откалибровать. 

Калибровка IMU (датчиков инерциальных измерений) на квадрокоптерах DJI

Также как и при калибровке подвеса ставим дрон на ровную плоскую поверхность. 

Затем необходимо нажать в правом верхнем углу 3 точки, чтобы войти в меню. 

Выбрать верхний пункт (иконка квадрокоптера).

Пролистать вниз и выбрать «Advanced settings». 

Еще раз в самый низ — пункт «Sensors State». 

Ниже показаний датчиков находится кнопка «IMU Calibration». 

Нажав на нее следуйте подсказкам на экране. 

Важно: После калибровки перезагрузите коптер. 

Если калибровка подвеса и IMU не помогло?

Когда горизонт заваливает при поворотах коптера или не правильном направление камеры. Бывает, что при прямолинейном полете камера смотрит немного вбок. Или другой случай когда при повороте коптера горизонт как бы заваливает в одну или другую сторону. 

Здесь может быть замешан компас, так как именно он отвечает за направление. Причины — самые разные — от хранения на железной полке до долгой транспортировки в машине (особенно если в том же багажнике находится сабвуфер) или выхода компаса из строя. 

Компас как и IMU можно откалибровать самостоятельно. Нужно выйти на улицу, в место подальше от домов, крупных металлических объектов и строений. Желательно снять с рук часы (особенно смарт часы с магнитным основанием) и все металлические предметы. Включить квадрокоптер, подключить телефон к пульту управления. 

Затем необходимо нажать в правом верхнем углу 3 точки, чтобы войти в меню. 

Выбрать верхний пункт (иконка квадрокоптера).

Пролистать вниз и выбрать «Advanced settings». 

Еще раз в самый низ — пункт “Sensors State”. 

Выбрать правую вкладку «Compass» и нажать кнопку «Calibrate Compass». 

Далее следуйте инструкциям на экране. 

В случае успеха ваш квадрокоптер будет мигать зеленым.

В случае если калибровка не удачна — об этом говорит красное быстрое мигание диода на коптере, попробуйте переместится на подальше от металлических предметов машин, парковок, железобетонных конструкций и провести калибровку повторно.

В случае если после калибровка компаса не завершается успешно или подвес все равно смотрит вбок — проблему может решить обнуление компаса специальным устройством. Сделать обнуление компаса можно совершенно бесплатно в нашем офисе в Москве. Для этого запишитесь на процедуру обнуления компаса по телефону в шапке сайта, по почте или через чат на сайте и принесите свой квадрокоптер в назначенное время. Эта услуга бесплатна для всех.

Еще причины не нестабильной работы подвеса?

Есть еще несколько причин нестабильной работы подвеса, например, сильный боковой ветер. 

Известны случаи, когда силы ветра было достаточно, чтобы резко срывать камеру вбок. В таком случае исправить ситуацию может защитная бленда (бленда Mavic Pro Pro/Zoom, для Mavic Air и для Mavic Pro). Она не только избавит от боковой засветки объектива, но и защитит чувствительный стабилизатор от ветра. 

Вторая часто встречающаяся особенность — завал горизонта в резком повороте. Здесь как такового решения нет. Минимизировать эффект можно калибровкой подвеса/IMU/компаса/сбросом показаний компаса, но в некоторых случаях убрать совсем практически невозможно, правда стоит различать 2 случая — первый, когда при остановке горизонт встает ровно, а второй — нет. Во втором случае проблема может оказаться механической — покажет только подробная диагностика, которую можно провести в нашем сервисе.
