Why is DJI Mini 2 Controller Beeping? 5 Causes & How to Fix?

Why is DJI Mini 2 Controller Beeping? 5 Causes & How to Fix?

People seem to have this issue where their Mavic mini 2 controller makes a continuous beeping noise.

Then the question comes: why is DJI mini 2 controller beeping?

A low battery, a joystick that isn’t aligned properly, or a firmware problem are generally the most frequent causes of a persistent beeping sound from your controller. Your battery charge level, controller calibration, firmware update, or a rollback can all be used to fix these problems.

Let’s take a closer look at some of the most typical reasons why your controller may be beeping continuously.

Why is DJI Mini 2 Controller Beeping?

Below are some most common causes we list.

1. Obstacle Avoidance Noise

The noise that many drones make when trying to avoid obstacles is the first problem that you might run into. Many drones now have forward-, backward-, and downward-facing sensors that keep the drone safe while in flight thanks to advancements in drone technology and the declining cost of sophisticated software features.

The drone is prevented from flying too close to any obstacles by these sensors, which recognize any obstacles in its path. The drone will stop moving forward (or in the direction of the obstruction), and the remote control will start beeping rapidly continuously.

This noise is merely intended to let you know that the drone won’t be moving any closer to the obstruction because doing so would put both the obstruction (which could be a person) and the drone in danger.

When the drone is in sport mode, some of these sensor beeping alerts are turned off. Sport mode, or advanced flying modes, disable all obstacle avoidance monitoring, allowing the drone to fly directly into objects in its immediate environment.

Except when you are competing or flying close to trees or buildings to capture amazing cinematic footage, it is not advised to switch your drone to sport mode.

2. Low Battery

Another possible explanation for your drone’s continuous beeping is that it is alerting you to the drone’s critically low battery. It sounds like this:

Once the drone’s battery has less than 20% of its capacity left, the controller will begin to continuously beep. This is a typical aspect of operating a drone from a producer like DJI.

Low Battery

Pushing the power button once on some DJI series drones will turn off their alarms, but not all of them have this feature.

3. Firmware Update Failure

One of the most crucial elements of drone ownership is routine firmware updates. Updates to the firmware keep your drone’s safety and security up to date with the most recent standards. Although these firmware updates are designed to enhance your drone experience, there are a few rare problems that could result in beeping or a firmware update that doesn’t work at all.

To check the current firmware on your drone go into the aircraft status of the app and check to see if there is a warning that says “RC requires update”. If there is a firmware update, you should proceed and follow the on-screen instructions while you wait for the new firmware to be downloaded and installed on your drone and software.

To ensure that your drone functions properly, you may occasionally need to update or downgrade the firmware. In the DJI GO4 app, tap and hold the three horizontal lines in the upper right corner for more than five seconds to update your firmware. This will display the current firmware version and a button that lets you update or downgrade your firmware.

To check if the beeping has stopped, downgrade or refresh your firmware.

4. Miscalibration on Joysticks

The left or right joystick may be out of alignment or not detected in the center of the joystick’s movement when you first turn on the remote control and connect to the drone, as indicated by the possibility of a continuous beeping.

Enter the app’s joystick calibration section, go through all of the prompts, and follow the on-screen instructions until the calibration of the joysticks is complete to resolve this issue.

5. Stuck Button

If one of the buttons on your remote control is stuck pressed, it might also beep continuously. The movement of the buttons is very shallow on every drone controller I have touched. This means that it is impossible to determine whether a button is stuck pressed simply by visual inspection.

Each button on your drone controller must be pressed in order to be tested, and you must listen for an audible click or a physical and mechanical click. If any of the buttons do not respond to pressure or do not emit a sound, you should try to figure out what is causing the button to remain pressed.

The most likely explanation is that a foreign object got caught around the button’s edges and caused it to become stuck. To gently outline the button’s edges and remove any sticky buildup that may be there, use a toothpick and isopropyl alcohol.

How to Stop DJI Controller Beeping?

Some suggestions for troubleshooting are provided below.

1. Recalibrate the Controller

  1. First turn on your controller
  2. Your tablet or mobile device must be connected to the controller.
  3. After that, start the DJI Go app and turn on the remote control.
  4. Select RC calibration by pressing the remote control icon.
  5. Make sure both control sticks are in the middle, then press the start button.

2. Update/refresh Controller Firmware

  1. Power on the remote controller
  2. Connect it to your computer using a USB cable provided

  10. After the firmware is complete, the controller will restart automatically

3. Stuck Buttons on the RC

Another sign of a stuck button on the RC is a continuous beeping.

If this is the case, the fix will be simple because it is simple to identify the stuck button by listening for an audible click or a physical click when pressed.

If any of the buttons don’t respond to pressure or don’t move when pressed, try to figure out what’s to blame, clean the area, then move the button slowly until it releases.

4. Recalibrate the Compass

IMU and compass calibration are crucial for a safe drone flight, so the beeping might be a way of DJI telling you to recalibrate them

Why is My DJI Controller Beeping While Charging?

Things are not working exactly as they should if your controller is beeping while it is charging.

If the controller was not powered down before charging, it may be beeping as a result. During charging, the controller ought to be turned off. Alternately, your controller might be in bind mode. The controller will beep to let you know it is in bind mode and ready to pair or connect with a drone.

When the controller is turned on, press and hold the power button for at least five seconds to put it in bind mode. Once it is prepared to pair with an aircraft, the controller will begin to beep to alert you. Avoid switching the controller to bind mode instead of turning it off.

Press the power button briefly, then immediately press and hold the button until the DJI remote controller turns off. If you unintentionally put the controller in bind mode, you can simply turn it off as usual or wait for at least 20 seconds for the bind mode to expire.

Your controller should stop beeping during charging once you have shut it down properly.

Each drone’s controller has its own peculiarities. It can be very frustrating because the manuals for each controller only briefly mention the common issues, and sometimes they solve the issue while other times they just produce the same issue.

The fixes listed above should give you the knowledge you need to comprehend why your controller is beeping and how to handle any problems that need to be resolved, regardless of whether it’s a DJI FPV controller, a Mavic 2, a DJI Mini 2, or any other DJI drone.
