Dynon ADSB no ATC data suddenly?

[prepperpilot]

Left message with dynon support.
Avionics upgrade completed 2yrs ago. All components are new Dynon HDX with exception of Garmin 175. All was working as normal. I normally get a check from local ATC every month or so. All seemed to be working. I get traffic and weather data as normal. Also see all info on FlightAware and ADSB exchange. I also show up on everyone else ADSB target on their equipment.
But ATC is not getting any data for some reason now.
Checked settings. On transponder setting it states Transpondwr Non Compliant now.... Don't know why.
Has anyone else had same issue..... I am perplexed. Don't want to get a nasty letter from ADSB police as unauthorized airspace pirate.
Thx friends
Chris

Is there a resolution you can share that might help others in your situation?

Resolution was obviously in settings.
For some reason in last software update the serial port that was re-configured for ADSB and GPS antenna. They have to match. For some reason the update changed the serial port setting to a GPS antenna that was not installed. It was old Dynon sv250 gps antenna that was no longer compliant. Somehow that data for ADSB info goes through transponder. Well, that data was not making it OUT to atc. So I got Trans ponder non-compliant message. Switching to the SV2020 in serial port settings instantly provided all data. No more ADSB Partial message on screen either.
I urge everyone to save their config settings before you do a software update.
Dave from Dynon was great and solved problem quickly.. Great support from Dynon.
