All The DJI Drone Blinking Light Errors & How to Fix Them!

DJI uses a lighting system to show the user what is happening with their drone. While the green, blue, purple and most colors are positive indications, the yellow and red lights are used as warnings and errors.

Having a few blinking lights is one of the most common problems that drones face. This is an article on all the flashing light errors that you might be getting when using your DJI drone. Let’s take a look at what they mean and how to fix them.

My DJI drone is blinking yellow quickly

When a DJI drone blinks yellow rapidly, it indicates that the remote controller’s communication with the drone has been lost.

There are a few options available to you in this scenario to regain the signal.

How to fix it

If you are close to the drone, the most popular fix is to restart the aircraft and the controller by turning them off and back on.

If this is unsuccessful, ensure that:

1. There aren’t any obstacles in the way since they can prevent signals from reaching the aircraft from the remote controller.
2. The antennas are aimed toward the flying object.
3. There are no wireless gadgets operating at 2.4 and 5.8 GHz that might also obstruct the signal.
4. High-density Wi-Fi signal sources are avoided.
5. You disable Bluetooth on your mobile device.

Additionally, it’s conceivable that the drone or remote controller has a hardware problem. To rule out that possibility, try flying the drone in a different area with less interference. If you still have the same issue, then just contact DJI Support for assistance.

The DJI drone is blinking red

Your DJI drone’s red blinking light indicates an IMU (Inertial Measurement Unit) error. This error typically happens after a long ride (more than 30-40 km), after a temperature change, or following a firmware upgrade.

The drone’s navigation system depends on it to keep it steady and horizontal in the air. Your drone wouldn’t be able to fly without it, and even if it could, it wouldn’t be able to navigate as effectively as it could with a functional IMU.

How to fix it

A common solution would be to recalibrate the IMU. Fortunately, DJI drones include a secondary navigation system called ATTI (Attitude Mode). In this mode, the drone utilizes its onboard sensors to locate itself in relation to the ground and identify its direction.

However, until you can return your drone home to recalibrate the IMU, Attitude Mode will lock the altitude of your drone.

To calibrate, use the DJI app, and adhere to the on-screen directions. You can run a calibration by doing the following steps:

1. Launch the app.
2. Go to General Settings.
3. Then go to Advanced Settings > Sensor > IMU Calibration.
4. Start calibrating the IMU.

The calibration method varies from one DJI drone to another so just follow the instructions in the manual guide.

The DJI drone is blinking red slowly

This is not a severe issue so don’t panic. If your DJI drone is blinking red slowly, it means that the battery is running low and needs to be charged as soon as possible.

To prevent this from happening in the future, it is recommended that you charge the drone before each use(preferably the previous day) and always monitor the battery level of the device so you can land the drone safely before it runs out of battery.

Drone batteries and batteries in general, are known to slowly discharge even if they are not in use.

My DJI drone is blinking red quickly. What should I do?

If a DJI drone’s battery runs out in the middle of a flight and there isn’t enough power to return home and land, it will start blinking red light rapidly.

Fortunately, drones have a kind of emergency mode called “critically low battery-landing,” so they might not go back to where they started, but they will still make an effort to land at their current location.

It is critical to land the drone right away and recharge the battery in this scenario.

What should I do if my DJI drone is blinking red and yellow alternately?

DJI drones come with a built-in compass that helps the drone determine its orientation and navigate its surroundings.

If the compass becomes out of sync, it will blink red and yellow alternately to signal a need for calibration.

How to fix it

To calibrate your compass, follow these steps:

1. Launch the app.
2. Go to General Settings.
3. Then go to Advanced Settings > Sensor > Compass Calibration.
4. Start calibrating the Compass.

After that, just follow the instructions on your drone.

Why does my DJI drone have a solid red light?

If your DJI drone has a solid red light, this means that there is a Critical error. Try turning the power off and then back on to see if it helps. This is the indicator that you don’t want to get no matter what.

The user can fix every other issue but this one is pretty severe. If the red light remains after turning the power back on, contact DJI support since you’ll most likely have to use the warranty.

Final Thoughts

As one of the leading manufacturers in the drone market, DJI quadcopters are the most commonly used drones by amateurs and professionals.

However, DJI drones are not excluded from errors. In fact, there are some serious errors that can occur which may force you to call on a specialist.

I hope this little guide provides some insight into why your drone lights are flashing and how you can fix it without sending your machine in for several hundred dollars worth of repairs or activating the warranty!
