Today as a few days ago I continue to have some disconnections from the app.
I noticed that this happens when I'm in the air, and I change from Tripod to P. As if they don't like it or there is a bug.
I get win with the latest firmware version than with the previous version.
Any advice?
For DJI, we have some problems, if you tell me where to retrieve the connection logs..maybe you understand something. thanks.

This once only happend to me with my Mavic 2 Zoom at full signal strength after I updated the latest SC firmware. The drone distance was only some 30 meters at an altitude of about 100 meters. Not sure if I used the flight mode switch, though. I turned the SC off and on again and luckily the connection resumed immediately.

However, after I relinked the SC with the drone it never happened again so far. So it might not be the worst idea to relink the equipment after an update.

After reading your post I got a little nervous and decided to do some tests by placing the drone in a remote room, connecting it and turning it on with no propellers installed. Because of the walls between the SC and the AC the signal strenght was only like 3-4 bars. I did this because I wanted to simulate a certain distance. I played with the flight mode button but the connection stood rock stable.

Have you tried to relink the SC with the drone after updating?

Yes, I did.
I will try to do it again, but it would be useful a log that highlights the cause...which is not recorded.
I would say that flying with the smartcontroller is becoming more and more an anxious and risky experience every day.
I don't know if it's possible, and here DJI could help us, if it's possible to activate some debugging mode so that we can record everything and eventually use it.
The only doubt I have is that these problems may be caused by a misuse of the memory card inserted in the smartcontroller by the smartcontroller itself.
In your case was you had a memory card inserted?
I will try to fly for a while without a memory card, to "test" this option too.

Hello maurotandofilm, I'm sorry for the trouble this has caused you and I can't imagine how you feel right now. Have you updated the Smart Controller firmware using the DJI Assistant 2. There is a specific instruction that a Smart Controller with a firmware version of v01.00.04.75 or earlier must be updated using the DJI Assistant 2.

You can follow the instructions in the video tutorial as for guidance on how to use and where to download the DJI Assistant 2.

More over, you can also set the DJI Go 4 app back to default by clearing its cache.
1. Select DJI Go 4 then see Settings.
2. Tap "Clear Cache"
3. Next tap Check for update.
4. If no update you can skip and close the app and re-open.
Please let me know the result. Thank you.

hi, I wanted to ask if you have solved the problem .... I have been having the same problem for two months .... I changed 2 smart controllers but still the same disconnection problem.  Try 3 different micro sd ..... updated with DJI Assistant 2 .... contacted DJI technical assistance ... NOTHING .... keep disconnecting .... cleared cache .... I am convinced that it is  a Software Bug ... if you solved it how did you do it ????

Yes, but it happens randomly.
Since the smartcontroller control remains active (as we know there are two signals, one from the remote control and one from the app, for video etc), the problem is certainly not the smartcontroller, but the cause of these disconnections me app DJI go 4, which is not developed to handle certain exceptions.
When does it happen at the moment?
1. if you first turn on the drone and then the smartcontroller
2. if you enter the smartcontroller options menu (scroll down drop-down) when you are in flight (perhaps to change the brightness)
3. with the DJI go 4 version with the French version, and after they added the DJI Fly.

In my opinion this is not the smartcontroller but the software (no regression test).
Hopefully they will solve it with smartcontroller 3.0 or Sony with its "Airpeak" drone which will be presented at Marxo 2021...do better :-)

thanks, but in the meantime it keeps disconnecting .... to avoid problems I also use the original controller in slave, of course spending 650 € for the dji go 4 app that crashes constantly IS NOT THE BEST .... thanks a lot

hi everyone, i wanted to ask if anyone knows how to disable the message - popup - on smart controller firmware upgrade .... if i downgrade to firmware v.01.00.0700 it is more stable and there should be no disconnection.  Now the firmware installed is v.01.00.0820 the latest .... but I don't have a mavic air 2 !!!  if I downgrade to the old firmware, every time the smart controller is switched on it keeps telling me that it is available in new firmware !!!  thank you all
