And before you ask Gary (I love ya), that is the ONLY NMEA sentence being omitted, i.e. that is the complete log.

Here are the Python dicts returned by next() etc.

When I look at the TPV dictwrapper, there is no 'time' key. There was in 3.19. Also, 'status' is missing as well.

Sorry, 'status' is not missing clearly. But the UTC time of pos is ('time').

Well it is missing for a little while and then gets emitted. I guess Gary this is the new heuristic to figure out status kicking in. I'll also take a look. But 'time' is still just gone..
