This weekend I was doing the first flights with MA2 and on several flights, the message "Aircraft not connected to RC" appeared.
It happened both at 30 meters and 100 meters and always with RC pointing to the drone, without obstacles, and with the transmission signal at the most.

The cell phone screen was simply black and white and frozen with the message in red (this is the print screen of the log).

in none of the cases, it seems to have automatically activated the RTH, but in one of the times I activated it myself and it corresponded while the cell phone's display continued with the error message and without being able to see the image in real-time.

I have a Xiaomi Mi A1 with DJI Fly v1.1.5(763-googleplay) and I have everything else updated with the latest versions.

Where might the problem be?
In Remote Controller?
In the aircraft?
On the mobile phone?
Is there any other LOG that I can analyze to understand why RC lost connection with the aircraft so many times?

Aircraft firmware v01.00.250
RC firmware 01.00.0250
App version 1.1.5
Cache When Recording Deactivated
Definition: Smooth
Frequency Dual-band
Channel Mode Auto

Since you were able to control your AC from RC while the screen was frozen, the most likely culprit is your mobile.Reinstall DJI Fly app and try again.

I don't see your mobile device on the approved list. Is it approved by DJI? I have used some unapproved devices that are ok at times, but not others.

No, my mobile phone is not on the compatible list, but I can't find any requirements regarding the App.
I see "old" mobile devices in the list and only a few newer models.

What should be the main requirement of the mobile? RAM?

Have you tried with a different phone/ tablet, that would isolate the problem to your phone ?

Ensure WiFI and bluetooth is disabled and that all other apps are shut down in the background. If that is already the case then it is simply a case that your device is not compatible to use the Fly App which requires 64 bit.

Thank you all for your feedback.

This weekend I'll try with one iPhone 6S to see if the problem is on my mobile phone. The iPhone 6S is in the approved list by DJI.

I'll come back later to give feedback.

Your description of the problem seems to point to either the phone or the cable to it. Unfortunately, the error message says it is a bad link from the drone to the remote (RC), but that is not always the case. You will get the same error message when the problem is with the link from the phone to the remote. Since there was no automatic RTH and you were able to control the drone via the RTH command, that indicates that the link from the drone to the RC was ok.

Hello nonuf.. i also face the these type of issue can you tell me how to solve it please

I haven't solved it yet.
I've read several reports that it could be a problem with the USB cable and so I bought a new one, but I haven't tried it yet.
I hope to have availability in the next few days to test it. I will give feedback

It happen to me once in a while. For me, it is between the cable and my iPhone.  There is a little problem with my lightning connector...

I think the message you get when the RC is not connected to the mobile device is "RC not connected".  I get that when the plug into the phone gets bumped.  Try it by unplugging your phone.

Today I flew about 5 batteries and I didn't have the error I had before

What I did was buy a new cable (it's not from DJI because it was sold out, but the one I bought at Amazon said it was for Mavic Air 2, and I took the risk)

At least today it didn't give the error luckily (the phone only blocked once, but because it was receiving video to cache, after deactivation it didn't block anymore and even when it blocked it didn't show up a lost connection message)

Tomorrow I'll try to make some more flights and if there's a change I'll give feedback

Approved device is recommended and already tested for compatibility

ok, but there are a hundred devices on the market and DJI only tested a few... and the list was updated long ago I believe...
