Hi everyone,

Today while I was getting ready to fly, the camera feed on the DJI Go app froze and it displayed a message in the corner «Remote controller connection error». The RC itself seemed to still be connected to the drone and working fine. I unplugged the controller from my phone and plugged it in again, however the app still wouldn’t connect. To solve the issue, powered off the RC and drone and powered them back on again. Everything seemed to be working fine for about 20 minutes, once I had finished my flight and was coming in to land I once again lost camera feed on the app and got the «Remote controller connection error» message again. I was still able to pilot the drone using VLOS and control everything normally using the RC, it was just the DJI Go app that was not working.
Unplugging and plugging my phone and even rebooting the controller didn’t help, the only fix seemed to be to reboot the drone which is strange as the RC still would work fine.

Drone is a Mavic Pro Platinum purchased four days ago and phone is a Samsung S8. Drone and RC are on latest firmware, DJI Go and phone are up to date.

Any thoughts?

First try a different cable.

• 
  
  

• #3

I would try a fresh install of the app and a new cable like Starz said.
If you did not have VLOS, would you be comfortable returning the drone with Just RC?

Yeah was definitely scary. I use an iPad connected with the bottom port and haven’t had the issue since. Have flown a bit with android using the bottom port as well and haven’t run into the issue again on that either.

I am using a Sony xzs phone on android with a type C cable that comes with the dji package connected to the side.

What cable you use for connecting it to iPad?

I use the cable included with the iPad (white apple one). From what I’ve heard the ones DJI include which connect to the side port are dodgy and are what cause all these connection issues.

I had my first flight today on my new mv2p in beginner mode! 4 minutes into flight i had the same ‘remote controller error’ message come up and the screen froze. I closed the app which cause the drone to RTH though i restarted the app and it reconnected with the drone before it actually landed. Using a Samsung s9+

I haven’t had the issue since using the bottom port of the controller, and not using the cables included with the drone that plug into the side port.

You could also try the Smart Controller (lol)

Thank jvl10. Will give it a go. As for the smart controller, I’ll wait till they have a 50% off sale! (Plus it wouldn’t fit in my ‘fly more’ bag!)

I’ve the same — RC wont connect to mavic 2 pro. firmware uptodate on both. tried the DJI tutorial — doesnt do what the tutorial shows. very frustrating. first flight fine — came home to extract video footage — found it was on onboard storage and not SD card — found that mavic 2 pro doesnt come with cable to link to PC!! I then found RC connection had failed. have raised a support ticket for both missing cable and unconnectability. Not great for an expensive piece of kit. had mavic pro before and never had these problems

• 
  
  

• #12

The M2 does come with a cable to connect the AC to your PC. That long flat cable is an A to C cable, same one you might use to connect the RC bottom port to a mobile device. Along with the cable, the M2 comes with a C to micro adapter.

• 
  
  

• #13

Hi and thanks Yes I saw that in the tutorials but mine didn’t! I also don’t have a cable to connect an apple device to the RC( usually use android but went to try an iPhone in case that worked — but the 2nd short cable that came with it, doesn’t fit the iPhone 6s). Camera view screen , on android device , just reads “remote controller connection error”. Going through the linking process , as per tutorials, results in “linking failed”

• 
  
  

• #14

great — DJI replied ….telling me how to format my SD card!! had neither read my email nor seen the images I sent showing device screen and the «linking failed» messages. My mavic 2 might be going back! I can’t use it. can’t believe the reply I had. DJI do you read these forums? can you step in and support ?

update on mine: today i was prompted to carry out a firmware update on the RC…. and it now connects fine

Thought I’d post here since that’s the topic with my issue with the most replies, though most of them are OT 😉

Anyway had the exact same problem a couple of times now with my new MPP and fortunately the RC to drone connection was OK so I hit RTH and then took over when it was close.

Seems strange that a cable could cause the RC to somehow «go bad» with a reboot required to set it straight but why not…Using the USB port in the bottom is going to require getting a 90° cable or adapter for the connection to the smartphone to not have the cable get in the way though.

Thanks and that’s one more thing to buy 😉 I still find it strange that a cable could cause part of the RC to «crash». Well I suppose we should be thankful that the connection to the AC still works when that happens.

Is there any history of people who used to have that problem with the side-port who never had it again after switching to the USB port ?

Cable connection issues will be ongoing in the community just because of the variety of cables available. Cheap isn’t always best.
Backup plan means more than one in the bag.

Yes but that seems to be a bit more than a «cable issue», more like an RC issue (microUSB connector, other hardware, software). Generally when a cable is faulty the connection between two devices is flaky/absent, here we have one device basically «shutting off» and then working fine again with the same cable once you reboot it.

If you are still a DJI Spark user you must definitely have some experience with DJI Spark error codes. When I was searching about DJI Spark errors, I found that most of them are so common to almost every other DJI drone.

Also, when I was on DJI forums, I found that some DJI Spark users are struggling with some DJI Spark errors. So I decided to write a simple article covering the most common DJI Spark error codes. Hope this article would help you to fix your DJI Spark error.

Error 1: DJI Spark IMU calibration error (code 50).

DJI Spark error code 50 stands for IMU (Inertial Measurement Unit) calibration error.

How to Fix IMU Calibration Error.

• Calibrate DJI Spark IMU properly. Power on the Spark aircraft and controller and connect to the mobile device. Open the DJI GO 4 app and enter the camera view. Go to Main controller settings> Sensors > IMU and hit “Calibrate IMU”. Then place the aircraft as shown on the DJI GO app screen to calibrate the IMU in different positions. Once the whole IMU calibration process is done, you are ready to check whether the error is gone.
• Change the calibration location and try again IMU calibration.
• Update DJI Spark Firmware.
• Factory reset DJI Spark using DJI Assistant 2. Download and install the DJI Assistant 2  from DJI Downloads Center to the PC. Then connect the aircraft to the PC using the USB cable and power on the aircraft. Open the DJI Assistant 2 and log in to your DJI account and choose the DJI Spark. Then hit “Factory Restore Defaults”.

Error 2: DJI Spark ESC error.

In most cases, ESC status error is caused by firmware glitches and faulty electronic speed controller (ESC).

How to Fix DJI Spark ESC error.

• Update DJI Spark firmware.
• Replace ESC. You can order buy a DJI Spark ESC for about 13$ and replace the faulty ESC. If you can get help from DJI Support to replace or repair the ESC, definitely try that way. Watch the below video for DJI Spark ESC replacement.

Error 3: DJI Spark gimbal gyroscope error.

DJI Spark gimbal error could be caused by glitched firmware and miscalibrated gimbal.

How to Fix DJI Spark gimbal error.

• Update or refresh Spark firmware.
• Calibrate the Spark gimbal. Check out the below video to calibrate the gimbal.

Error 4: DJI Spark air encoder error.

In most cases, DJI Spark air encoder error is caused by main board issue or firmware issue.

How to fix DJI Spark air encoder.

• Update or refresh the firmware.
• Replace the DJI Spark main board.

Error 5: DJI Spark remote controller connection error.

Usually, DJI Spark controller connection error is caused by crowded or poor signals, high levels of electromagnetic interference, and low battery power.

How to Fix DJI Spark remote controller connection error.

• Charge the DJI Spark controller and aircraft to a sufficient level.
• Face sides of antennas toward the drone. Instead of pointing, the ends of the antenna face the sides of the antenna toward the drone and point sideways of the antennas towards the drone for better signal coverage.
• Update DJI Spark firmware.
• Change the frequency of radio signals. A higher frequency (5.8 GHz) could help with a stronger remote connection with the aircraft. So try changing the remote controller’s channel frequency. Check the below video to know how to up the channel frequency.

Error 6: DJI Spark SD card error.

In most cases, DJI Spark throws the SD card error because of inserting an unsupported SD card or damaged SD card.

How to Fix DJI Spark SD card error.

• Check whether the SD card is compatible with the DJI Spark. Visit the DJI Spark Product Info page and check whether your SD card is listed as a supported SD card. Else try using a supported SD card.
• Repair the SD card using the Windows command prompt. Connect the SD card to the PC and open the command prompt. Then type “chkdsk” and leave a space and specify the SD card driver letter (Ex: chkdsk D). and hit enter. Once the process is done the sd card is repaired.
• Format the SD card.
• Update DJI Spark firmware.

Error 7: DJI Spark navigation system error.

Sometimes, DJI Spark navigation error causes by a temporary faulty Spark setting. So it’s better to first try restarting the aircraft.

How to Fix DJI Spark navigation system error.

• First, try restarting the aircraft.
• Update or refresh the firmware.
• Factory reset the DJI Spark.
• Calibrate DJI Spark IMU and compass.

Error 8: DJI Spark take-off error (code 200).

As On DJI Forums, this error is caused by firmware issues and faulty settings.

How to Fix DJI Spark take-off error (Error code 200).

• Restart the aircraft.
• Update the Spark firmware using DJI Assistant 2.
• Factory Reset the DJI Spark. Connect the Spark to the PC using the USB cable. Then power it on. Open the DJI Assistant 2 and choose the drone and hit “Factory Restore Defaults”.

Error 9: DJI Spark motor or propeller error.

This error is usually thrown because of uneven motor spinning. most of the time it’s caused by faulty propellers’ effects.

How to Fix DJI Spark motor error.

• Check whether propellers are installed in the proper pattern.
• Restart the aircraft.
• Replace the propellers with a new set. Slightly bent propellers could cause unstable flight and some motors need to spin faster to keep the drone stable. Therefore try replacing the current propeller set.

Error 10: DJI Spark error gimbal overload error (code 40003).

Most of the time, DJI Spark throws the “Gimbal Overload Error” because of restricted gimbal movement, faulty gimbal, faulty ribbon cable, or firmware issues.

How to Fix Gimbal Overload Error.

• Check Something is blocking gimbal movement.
• Update DJI Spark Firmware.
• Calibrate the gimbal
• Factory Reset the Spark. Connect the Spark to the PC using the USB cable and power it on. Open the DJI Assistant 2 and choose the Spark and hit “Factory Restore Defaults”.
• Replace the faulty gimbal cable.

Error 11: DJI Spark compass error.

Usually, Compass Error is caused by placing and flying the aircraft near magnetic fields which causes discrepancy with the natural magnetic field.

How to Fix DJI Spark Compass Error.

• Restart the DJI Spark.
• Avoid Electromagnetic interference. Avoid flying the Spark near powerlines, communication towers, huge buildings, etc.
• Calibrate the compass in an open wide area. Move away from the place where you currently receive Compass Error to an open area. Then perform a proper compass calibration. Read how to calibrate the compass.
• Contact DJI Support. If you still get the error, the compass might be faulty.

Error 12: DJI Spark battery error.

Usually, Spark battery error is caused by a faulty power management board and battery firmware glitches.

Fix DJI Spark Battery Error.

• Refresh or update battery firmware. Update DJI Spark firmware while keeping the glitched battery inside.
• Drain the battery to zero and recharge it fully.
• Change power management board. If the error still exists, the power management board might be glitched or damaged. So you would have to change the power management board. Advisable to contact DJI Support.
• Replace the battery.

Error 13: DJI Spark forward/ backward vision sensor error.

In most cases, DJI Spark forward and backward vision sensor error is caused by the miscalibrated sensor system.

How to fix DJI Spark downward/ forward vision sensor error.

• Restart the aircraft.
• Refresh or update the firmware.
• Recalibrate the forward and backward vision system using DJI Assistant 2. Check out the below video on calibrating vision sensors.
