Mavic suddenly switched to ATTI mode mid flight

[Dronason]

Hello Gents.

During literally my first flight with the Mavic today I had this same thing happen!

I don't quite know how to post logs or any of that yet as I'm a newbie. If anyone wants me to upload something point me in the direction if it's for the greater good.

Welcome,
You can use this web site and follow the instructions there:
DJI Flight Log Viewer - Phantom Help
Your flight will open in a new page with a unique url. Copy that page url and post it so other users can check your log file.

How did you manage to fly 4 hours? How many batteries did you use?

I used to get those errors often in 1st 3 months of flying. Entered ATTI mode sometimes every flight. Then all went well for a month, and then one day MP wouldn't take off due to a completely failed GPS module.

After DJI replaced both compasses, GPS module, and all flight boards, main PC board, and GPS module again, it now works perfectly, been a year and haven't seen that message since!

Sorry, this probably isn't helpful for your case, other than to send it to DJI if it is a recurring problem?
