DJI Mavic Pro keeps disconnecting mid-flight is a huge issue Mavic Pro users often face. Users are confused about this issue and keep asking for solutions and causes for this issue. So in this simple article, we are going to figure out why DJI Mavic Pro keeps disconnecting and how to fix it.
When researching this Mavic Pro keeps disconnecting issue, I found that there are two types of Mavic Pro disconnecting scenarios. So let’s have look at what they are and which scenario you are facing.
DJI Mavic Pro disconnecting scenarios.
As help for DJI Mavic Pro users who are struggling with the disconnecting issue, we would ease them figure out what’s the scenario of disconnection. Then we would be able to guide users to fix the disconnection issue according to the type of disconnection issue they face.
Scenario 1: DJI Mavic Pro aircraft disconnects from the remote controller.
If the DJI Mavic Pro disconnects from the remote controller, the remote controller would change its status to “Connecting…” status. Also, the aircraft would return home if you have set up it properly or it would hover or land. Because the aircraft completely disconnected from the remote controller, the user can’t control the aircraft anymore. When we would name this scenario as “scenario 1” and when we mention that you know we are on about this scenario.
Scenario 2: DJI remote controller disconnects from the phone.
If you are able to control the aircraft even after the disconnection, this is your type of disconnection. in this scenario, when the disconnected message popped, the video feed would turn black and the remote controller would work fine with the drone. When we would name this scenario as “scenario 2” and when we mention that you know we are on about this scenario.
Why does DJI Mavic Pro keep disconnecting?
Let’s have a brief look at why DJI Mavic Pro keeps disconnecting.
1. USB cable and port issues. (The biggest reason for the scenario)
This is the main reason for the Mavic Pro disconnection issue in scenario 2. When the cable that connects the controller to the phone is damaged or faulty, it would malfunction in the mid of the flight and disconnect from the phone and throw the disconnection message. Also, the side USB port of the RC is so faulty and better to use the USB port under the remote controller.
2. Firmware issues.
Most of the time, the DJI Mavic Pro keeps disconnecting (scenario 1) is caused by firmware issues. Some users started to face this issue after upgrading the firmware because of glitches in the upgraded firmware.
3. Low battery power.
It’s so important to keep the drone and remote controller battery power at a sufficient level if you are flying the drone over long distances. The far the drone flies, the harder it gets to receive radio signals from the remote controller if the aircraft’s battery is low. Also if the remote controller has low battery power, it would affect the strength of the radio signals it produces.
4. High electromagnetic interference.
If you are flying the DJI Mavic Pro near powerlines, communication towers, and huge buildings and suddenly the Mavic Pro this is the reason for that disconnection. When drones fly near that kind of high electromagnetic interference, drones won’t be able to receive radio signals anymore and disconnects from the RC. So it is advisable to avoid that kind of obstacle when you are flying the Mavic pro.
5. Crowded and poor signals.
Because people are using many electronics with low-level frequency (2.4Ghz), they are so crowded and the drone might be unable to pick the right signals and cause disconnection.
6. Hardware issue.
Also, this could be a hardware issue of the Mavic Pro aircraft or the remote controller which requires DJI support or professional help to fix.
How to fix DJI Mavic Pro keeps disconnecting issue.
Let’s see how you can fix the causes of the disconnection and fix the DJI Mavic Pro keeps disconnecting issue.
Step 1: Replace the USB cable.
This step would help to troubleshoot the Mavic Pro disconnection (scenario 2) issue, who are facing the Mavic pro disconnection issue because of disconnection between the remote controller and phone. Even though you are not facing that kind of disconnection scenario, I recommend you replace the USB cable and connect it to the USB port under the remote controller.
- Replace the current USB cable with a strong USB cable.
- Connect the USB cable to the USB port under the remote controller. This port won’t malfunction even though the side USB port malfunctions often.
Step 2: Charge the aircraft and controller batteries full or to a sufficient level.
As I mentioned before it’s so important to use fully charged batteries for Mavic Pro aircraft and controller to keep a strong wireless connection. Especially if you are flying the drone at a long range.
- Charge the Mavic Pro aircraft and controller batteries fully or at least 75% before using them.
Step 3: Upgrade/Refresh/Downgrade the firmware using DJI Assistant 2.
Next, let’s make sure you have installed the latest firmware properly. If you are starting to get this issue after updating the firmware, you better try to “downgrade” the firmware instead of “refresh” the firmware. Also, I like to use DJI Assistant 2 for Mavic for this kind of operation instead of DJI GO4.
- Download and install the DJI Assistant 2 application to the PC.
- Open DJI Assistant 2 application and log in to your DJI account connected to the Mavic Pro.
- Then connect the Mavic Pro aircraft to the PC using the USB cable.
- Turn on the Mavic Pro.
- Once the DJI Assistant 2 detect the DJI Mavic Pro it would pop the Mavic Pro boc. Choose that DJI Mavic Pro box.
- Once you enter the firmware update panel of the Mavic Pro, you can find all the previous and latest firmware for the Mavic Pro.
- Click on the “Upgrade” or “Refresh” button in front of the latest firmware. (If you are stared to getting this issue after updating the firmware click the “Downgrade” button in front of the previous firmware)
- Click “Start Update”.
- Wait until the firmware is completely downloaded and installed.
- Then you need to upgrade/refresh/downgrade the remote controller’s firmware also. For that follow the same steps connecting the remote controller.
After this step, you can give a try a test flight and check whether the issue is gone. If it’s not move to the next step.
Step 4: Change the frequency channel of the Mavic Pro.
Let’s switch the Mavic Pro Wifi frequency channel for a better connection.
- Connect the remote controller to the phone.
- Power on the aircraft and controller.
- Then open the DJI Go4 app and enter the camera view.
- Tap on the three dots at the right top corner and tap on the wifi icon on the list.
- Now you will see the frequency spectrum on the screen. You’ll see stable channels in green, current channels in blue and unstable channels in red. All the channels below 100 are 2.4Ghz and above 100 are 5Ghz.
- Choose the “custom” option in the selection.
- Then scroll down and choose a channel index with stable quality.
- Then tap Ok.
Give another test flight and check whether the issue is gone. If it’s not move to the next step.
Step 5: Rebind the Mavic Pro to the remote controller.
- Connect the remote controller to the smartphone/tablet.
- Power on the remote controller and Mavic Pro aircraft.
- Open the small door (where you usually put the SD card) on the right side of the Mavic pro. Then You’ll find a small black button.
- Press that cute little button using a screwdriver or something possible. After pressing that the indicator on the side will turn red.
- Open the DJI GO 4 app and enter the camera view. Tap on the three dots in the right top corner and tap the remote controller icon.
- Then scroll down and tap “Linking RC”.
- Then select “Primary controller” and hit ok.
- Within 59 seconds the Mavic Pro aircraft would be linked to the controller.
Step 6: Fly the Mavic Pro without any disconnection.
Now we have troubleshot every cause of disconnection issues with the Mavic Pro. So now it’s time to give the final check to check whether the Mavic Pro’s disconnection issue is fixed.
- As I said charge the Mavic Pro aircraft and controller batteries before the flight.
- When flying avoid powerlines, communication towers, huge buildings, and other electromagnetic interference.
If you still getting the disconnection issue, move to the next step.
Step 7: Contact DJI.
If you are still struggling with the issue, there must be some hardware issues with the Mavic Pro aircraft or controller. I have written a whole article on how you can get support from DJI to fix your DJI drone issue.
