Indeed, but I think we've talked about this before with David and
"default" may mean "default for use with NTP". We'll see. Certainly the
single sentence is the best - I happen to use: $GPRMC.
I'm trying to make $GPGGA the default, it is a much more informative
sentence (using 'mode 2' in the server statement specifies this):
It contains the current time (hms), position (ddmm.mmmm), nr of visible
sats, DOP etc, which makes it easy to write a little perl script to
process the clockstats file to gather all sorts of interesting statistics..
Historically, the NMEA driver claimed to use any/all sentences in the
default (mode 0) configuration, but it lied and in fact treated mode 0
the same as mode 1, which is to say it ignored all but $GPRMC. This
was fixed during the period 4.2.5 was ntp-dev, and with the current
code, you really can use any/all of the supported sentences by
Nice! I get all the ntp hackers messages, but never noticed that fix.
