Technical Support / Re: Problem Receiving FLARM with Rosetta (in France)

This is a very puzzling case
Nothing showing on the database for any mode from 38533C from 6th April.
You say that the flights on 7th and 8th April were 'not really flights but ground tests at LFLE (Chambery)' - so I wouldn't expect to find any reports of reception for either of those dates from PWLFLG2 (Grenoble) at 40Km away, which is consistent with my comment that the only reports for those dates were Cellular.
Looking on the PilotAware Playback Site https://playback.pilotaware.com/playback/groundstations/ (...which is based on data collected by the PilotAware ATOM-GRID Network and via iGRID Cellular connection), your aircraft 'pops up' (via its cellular signal) on the ground at Gap Tallard at 16:17 (UTC ?) on 20240407 - a long way from Chambery!! It seems to remain there on the ground at Gap Tallard for about 2 minutes before disappearing 'offline' and I can find no other reports from it that day. In order to get there, by air, you would (presumably) have flown from Chambery right past Grenoble, yet there is no PAW (or ADSB) report on the database from PWLFLG2 to report such a flight. (That is explained by your comments, sent while I was investigating and typing this response, but why would your aircraft show up at Gap Tallard in the first place?)
The next time I can find your aircraft is the following day (20240408), reporting very briefly - again via cellular, but for a few seconds only, back at Chambery at 09:40 UTC before disappearing and reappearing (again via Cellular) apparently heading north past Pontcharra at 09:45. Your comment about the ground tests would explain the unit popping up on the ground at Chambery, but why would it reappear 5 minutes later about 10Km away at Pontcharra - unless that is something to do with the cellular masts that your phone was connecting to during your ground tests.
For completeness, I have just logged in directly to the ATOM at LFLG and it appears to be working normally, reporting both ADSB and Flarm traffic - as I would expect it to.
Hopefully Lee can throw some light on what may be going on.
Best Regards and Bonne Soiree
