Re: [gpsd-users] Garmin 18X LVC and upcoming week rollover

[Rich Wales]

I enabled PGRMF (./gpsctl -x '$PGRMO,PGRMF,1' /dev/gps0); see below for
my ./gpspipe output (including PGRMF sentences now).

I'm having a difficult time forcing this GPS into binary mode, btw,
despite several ./gpsctl -b commands and a few restarts of gpsd.  Is it
truly essential here for me to use binary mode in order for gpsd to
properly grab the leap second count that is now available via PGRMF --
i.e., am I wasting my time and everyone else's by running experiments in
NMEA mode?  Or is it simply a matter of "no need to use the clunky NMEA
mode, binary is better"?

Right now, gpsd is still ignoring the leap second count and is still
reporting timestamps in the year 2000, even after I've enabled PGRMF.
If I can be of any assistance in getting the WNRO bug well and truly
fixed, I'm certainly happy to help -- but if not, then I'll happily
continue using gpsd "as is" and compensating for the problem by fudging
the timestamp in ntpsec.  You may feel I'm being unreasonably stubborn,
but I simply and flatly refuse to throw away this GPS as long as I can
get it to work in that manner.
