Your DJI mini 2 slowly flashes red
A slow blinking red DJI mini 2 indicates that the battery level is low. The device is, in fact, equipped with a intelligent flight battery which provides the energy necessary for its operation in flight. Its capacity is 2 250 mAh. It can thus allow you to fly for a period of up to 31 min.
Your DJI mini 2 starts flashing red rapidly
When the charge level of the DJi mini 2 Intelligent Flight Battery is very low, the status indicator will start flashing rapidly. This is a signal that should not be overlooked. You will need to take a look at the battery level indicators and plug in the charger before it is completely discharged.
Your DJI mini 2 flashes red
Flashing red, your device is indicating an IMU error. This acronym is in English and means Inertial Measurement Unit which means " inertial measurement unit " in French. It is a measuring device that uses data collected by a gyroscope, accelerometer, barometer and thermometer to provide the device with useful information like angular velocity, specific forces, and altitude to help it stabilize. For a good measurement, the device must be calibrated. This error generally occurs when there is a change of environment (significant temperature variations, long trip over 50 km and others) or after an update.

This signal from the drone prompts you to proceed with compass calibration. Like the IMU calibration, the compass or compass calibration must be done after traveling a distance of 50 km from the usual place where you use your drone. It must also be done after a period of 30 days during which you have not used the device.
How to solve the problem causing your DJI mini 2 to flash red?
Once the diagnosis is made and you have the answer to the question " why is my DJI mini 2 drone flashing red? you can move on to troubleshooting.
Case of low or very low level of charge
When your drone's smart battery is drained, it is recommended to recharge it. You must therefore connect your charger when you observe a warning by slow or fast flashing red LEDs. Here are some instructions for charging your DJI mini 2:
- Plug it in 18W USB charger that is supplied with the device by DJI to an AC outlet (100-240 V, 50/60 Hz).
- Then connect your DJI mini 2 to the charger.
- The loading will start and you will be able to follow its progress thanks to the battery charge level indicators. It will be complete when all the LEDs are on. The time required to fully charge the DJI mini 2 Intelligent Flight Battery is 1 hour and 22 minutes approximately.
Case of a DJI mini 2 IMU error
When your DJI mini 2 drone flashes red for a IMU error, you need to calibrate it. The process is simple and only takes about ten minutes:
- Let the appliance cool down and lay it face down on a flat surface while ensuring that you have a charge reserve of at least 50% and its arms closed;
- Turn on the right and connect it to the DJI Fly app ;
- Click on the three dots on the top right corner to access System Settings.
- Open " Safety then scroll down to " Capteurs ».
- Select " Calibrate the IMU » then follow the different steps that the application asks you. You will successively have to pivot your drone horizontally and vertically.
- Finally restart the drone once the operation is completed and successful. If the calibration fails, reboot anyway and then try again.
Case of a compass or compass calibration fault
This case refers to flashing red and green alternately. For compass calibration of the DJI mini 2, follow the instructions below:
- Go outside, away from cars, telecom masts and structures that may cause interference.
- Power on your drone and connect to the DJI Fly app.
- Go to system settings by clicking on the three dots in the upper right corner.
- Then click on " Safety » and go to the section « Capteurs ».
- In front of compass, click on “ Calibrate "And then" Start to start the calibration.
- Follow the instructions in the app to calibrate horizontally then vertically.
- You must first hold the device vertically and then rotate it in the clockwise of a watch on 360 degrés. The light will then change from yellow to solid green.
- For vertical calibration, you need to point the drone upwards and rotate it around its axis 360 degrees. The indicator will also change from yellow to green here to indicate the success of the operation.
- When all calibrations are successful, the LED will start flashing green.
Following warnings from a drone DJI mini 2 flashing red, it is therefore important to carefully observe the flashing in order to decode the alert. It will then be necessary to solve the problem which can be a fault in the calibration of the compass or the IMU as well as a fault in the charging of the battery.
