I have dug into this a little further and found something odd. I found that the NMEA data is driven by /velocities/speed-east-fps and /velocities/speed-north-fps. So I calculated these and added them to my csv data file, and the playback config file. The oddity is that even though my file now has them, these values are not changing in FG. They remain 0. I am using the null FDM and a the generic protocol, and all else seems to be working correctly, except on the NMEA data, that is used by Atlas among other things, the heading and speed are showing as zero. Any ideas why I can't get the generic protocol to change these two velocities when it can change other values just fine?
