    At a flight this evening I lost connection. RTH but didnt reconnect on the flight back. Was only approx 300m away. LED on controller turned red and stayed red.
    Never happened before.
    Phone I use has no SIM card and is only used for flying.
    There might have been some interference in this area but usually it would reconnect on the way back.
    Flight protocol attached and it just stops where the connection broke.
    Hope someone here has a tip for me what the issue could be. Afraid to fly again, should I bring it back to the dealer?

    Thanks for your help!

    There was no indication in the log of any impending signal problem prior to the disconnect. Does it connect again now when powered up?

    That's a tough one to diagnose in that case.

    Is there any other data I can share with you to find out the issue?

    It was scary because the start point wasn't recorded accurate and it landed high up on a bastion which is normally not accessible. I was lucky in a way because if it would have landed 3-4 meters to the other side where it started it would have landed in the sea.

    You initiated takeoff before the home point was recorded, and with only 12 satellites locked - that's likely the reason for the location. The DAT file from the aircraft might shed more light on what happened, but I don't think that those are currently accessible and readable on the MA.

    You have the DAT file(s) from the mobile device, or from the aircraft itself? Or both?

    so this has happened before and you continued to fly in the same area ? any reason why ?

    no and no. Was flying in the area before yes but never had a problem.
    What I meant is that there are other wifi signals. When I had connection issues before it was because it was too far away

    Yes - the aircraft DAT files are big. Unfortunately that one seems to suffer from the same problem as many (all?) the recent MA DAT files - it's not readable by DatCon.
