Losing connectivity alot

Skytex83 · Feb 28, 2022

My M2Z keeps losing connectivity and I'm not sure what to do. I've changed usb cables, devices, which port i plug into on the remote. I think maybe a loose antenna in the drone? it seems that yawing can effect it, and range or flying doesn't make much difference. when the connection is good its great but then when it isn't i can't be 2 feet from the drone and it'll disconnect. attached is a video i made of the issue.

Is this issue the same when the car isn’t involved?

Not sure if you have solved your problem but apparently this is a known issue. I also had the same issue with my Mavic 3 Cine. The problem seems to be limited to early units, at least that is what I have heard. I received mine in late November 2021. Out of the blue the craft disconnects from the controller. In some cases it was happening within 600 feet of home at 100 feet altitude, clear sky no obstructions, nothing nearby. After disconnecting it pauses then RTH. One time it RTH over 200 feet from home and tried to land over a lake. It reconnected just seconds before landing in the water and I was able to abort the landing.
This drone has flown perfectly for months until now, the only thing I can say is that the problem becomes persistent when I perform master shots. Right after that the drone acts all crazy and the disconnects start.
I did everything DJI told me to do, checked everything, updated everything but didn't help. Randomly it disconnects. I have flown up to 4 or 5 batteries with not a single issue then all of a sudden it starts again.
Well I filled out all the paperwork and just last week sent the drone to CA for service. Within hours of it arriving at DJI I received a phone call from a service rep asking me if I wanted any of the files on the drone. I politely told her no and then we talked a little bit about the drones random behavior. She thanked me and told me to be patient, the Drone would be looked at by the service team. That was Thursday, May 5th. Friday May 6th I received an update that my drone was diagnosed and it was determined that it needed to have the IMU replaced. The email told me that the repair would take a few days, to be patient. Ok, I am patient. Monday May 9th I received another Email that my drone was repaired and was going to Quality Control, then would be shipped. Please be patient. This could take up to 3 days. Two hours later I received another Email, drone was shipped with a tracking number, please be patient.

My take on all of this?
1. DJI Service is actually pretty outstanding. Their concept of being patient is more like my concept of expediting.
2. They didn't test anything. I believe they disassembled my drone, or checked the build specs against my serial number, and knew right off the bat that I had a bad IMU. What I am reading on the forums makes me believe there was a batch of these drones that had a defect. Many people on these forums have had their drones repaired or replaced because of these disconnects and the common thread is we are all the earliest recipients of the drone.
3. DJI has not embraced the American concept of mass recalls for their products. I believe many more of you out there have a hidden defect in your drone and someday it will disconnect for no apparent reason and you will never see it again. I just got lucky.

At one point I considered paying the $230 and refreshing the drone because I had no faith that sending the unit back would solve the problem due to the randomness of the issue. Well let's hope it doesn't happen again. But if it does I will be less concerned over losing my 5k drone. It's a matter of record now that the drone had a problem, DJI repaired it, and it shouldn't have another problem. If it does it again and I lose the drone, I assume DJI will take responsibility and replace it on their dime.

I actually haven't Interesting to know about the IMU issue. I haven't ran across it. I'd love more info/links as well as how to send the drone off without having dji refresh on it.

You send it in for warranty service. If the drone is experiencing issues that are not the result of a crash or neglect, DJI will honor the warrantee and fix your drone. The link I was provided after contacting customer support was this:

To get started with your Online repair request click: DJI

I followed the instructions and ultimately was emailed a mailing label and instructions on how to send the drone back. They only wanted the drone, nothing else. No batteries or anything.

Wrap it in bubble wrap, put it in a box and put their label on it. Ship it and have faith, they seem to have this process pretty well in hand. Even though their website warns that repairs could be delayed, they are actually turning products around within 5 to 7 busines days of receipt. Mine was shipped back 5 days after receipt however two of those days were weekend days.
