I have not yet been able to test the Flarm (and FlarmNet) part.
If only the last 3 digits of the ICAO HEX appear, that means that the FlarmNet database decoding is indeed not working.

I was in touch with FlarmNet support and Tobias mentioned that the FLarmNet database is now compressed. This allowed them to revert back to a single worldwide file (the "All Data" link). So no more separate regional files.

A few days ago, the links to the FlarmNet files for 3rd party devices were disabled. I guess they were still working on them.
I checked the FLarmNet download site a moment ago and I now see that LXNavigation, XCSOAR, LK8000, WinPilot (and others) links are up again.
