The DJI Mavic Mini, DJI Mini 2 and DJI Mini SE are all different drones. Please make sure you know which drone you have.
This page is dedicated to the Mini 2 but the troubleshooting steps and the if X is not working, check Y, replace Z is generally pretty similar between the 3 models, but the parts are mostly *not* interchangeable.
| Error Code(s) | Problem | Check | Solution |
|---|---|---|---|
| 40021 | Error message "Gimbal IMU data error. Contact DJI support for assistance" | Did you just replace the gimbal/camera assembly? If you did, that is the cause. Every time you replace the gimbal/camera assembly you will get this or similar error message. There is a way to make the new gimbal/camera assembly work correctly, but as far as I know there is not a way to remove the error message. It's a lengthily process, I will add more details when I can. | To make it work correctly, use PYSerial and DJI tools. |
