I made a couple of flights yesterday with a new setup that links a PowerFLARM brick (2.79/3.1/Flarmnet loaded) to an SN10B (2.37, PDA, FLARM, 19200 selected) passing Flarm, GPS, and vario data to an Oudie2.

All worked exactly as expected EXCEPT that randomly during flight, at irregular intervals, I would get a momentary GPS dropout in the Oudie, indicated by either a PRIMARY GPS BAD followed immediately by a PRIMARY GPS OK caution on the Oudie, or more frequently just the PRIMARY GPS OK caution.

Green GPS bar on the Butterfly display never changed, and only once did the SN10 give me a bad GPS info warning, but I did see the map change from centered to offset on it's own occasionally.

Logger files from both the PFB and SN10 look good.

I'm not an expert, but could there be a problem with the 19200 baud rate dropping GPS data while trying to merge and pass it all on to the Oudie?

I haven't had a chance to try running the Oudie directly off the PFB to see if that isolates the problem.

A friend of mine flying with his PFB hooked up to his SN10 (no Oudie) said he had similar problems, so I wonder if it is the PFB GPS output that is a bit erratic.

Anyone else seen this kind of behavior?

Except for this annoyance, the setup worked like a dream, with all the displays working together to provide really good situational awareness. Flarm on the Oudie is awesome!
