NMEA Output with RTK Fixed Input

Hi,

I am pushing NMEA output through the TELEM2 port to a RFD900x to get the data to a system. I have both a Here 3+ running along with an Emlid M2 running RTK. I think I have everything configured so ArduPilot uses the RTK Fixed data from the M2 when available, and it kind of looks like RTK stable signals coming in the NMEA data stream, but the quality flag doesn’t show it is using RTK data.

Q1) Is it possible to get the NMEA data stream to update the data quality flag in the GGA sentence to show 2 or 4 (NMEA version?) when using the RTK Fixed signal?

What I get:
$GPGGA,172918.185,2958.28684,N,10307.16280,W,1,06,02.0,1641.54,M,0.0,M,*48

What I was expecting
$GPGGA,172814.0,2958.28684,N,10307.16280,W,4,6,1.2,18.893,M,-25.669,M,2.0 0031*4F

In the two sentences above, the quality flag is after the “W”.

Thanks,
Keith

Retest after updating to ArduCopter 4.4.4
AFAIK the NMEA output has improved there, not sure if this particular use case is addressed or not…
