Re: [gpsd-users] Fwd: GPSD usage with Garmin 16x GPS module

[lokesh kumar Nijalinge]

Thanks Gary and George.

We were able to solve the issue.
Including  -b  option while running gpsd made the trick.
Yes surely GPSD tries to communicate with GPS module.

Thanks,

Lokesh

Yup.  Until plain 'cat /dev/ttyS0' works there is not much point
complicating the test case.  Just be sure your 16X is in NMEA mode.

Without the -b option, documented in the gpsd man page, gpsd tries
send a few probes and configuration items to the GPS.  With -b it send
nothing.  Either should work fine, as long as you see good data with the
'cat /dev/ttyS0'.  No data, then nothing gpsd can do with nothing.

At some point you will want to be able to send data to the GPS so
you really should hook up the data out line.  If nothing else, 4800bps
is way too slow for mmuch of anything, so you need to be able to bump
the speed up.
