$ ./gpsd -nN -D2 /dev/rfcomm0
gpsd: launching (Version 2.96~dev)
gpsd: listening on port gpsd
gpsd: running with effective group ID 1000
gpsd: running with effective user ID 1000
gpsd: opening GPS data source type 4 at '/dev/rfcomm0'
gpsd: speed 57600, 8N1
gpsd: speed 9600, 8O1
gpsd: speed 57600, 8N1
gpsd: gpsd_activate(): opened GPS (fd 5)
gpsd: NTPD ntpd_link_activate: 1
gpsd: /dev/rfcomm0 identified as type Generic NMEA (2.669800 sec @ 57600bps)
gpsd: => Probing device subtype 0
gpsd: GPS on /dev/rfcomm0 is offline (0.000683 sec since data)
gpsd: => Probing device subtype 1
gpsd: => Probing device subtype 2
gpsd: unknown sentence:
"$GPGSV,2,1,08,12,76,358,,09,51,120,,30,50,274,,27,42,122,*75\x0d\x0a"
gpsd: => Probing device subtype 3
gpsd: GPS on /dev/rfcomm0 is offline (0.000315 sec since data)
gpsd: => Probing device subtype 4
gpsd: => Probing device subtype 5
gpsd: unknown sentence:

gpsd: => Probing device subtype 6
gpsd: GPS on /dev/rfcomm0 is offline (0.000301 sec since data)
gpsd: => Probing device subtype 7
gpsd: => Probing device subtype 8
gpsd: unknown sentence:
"$GPGSV,2,1,08,12,76,358,,09,51,120,,30,50,274,,27,42,122,*75\x0d\x0a"
gpsd: GPS on /dev/rfcomm0 is offline (0.000276 sec since data)
gpsd: unknown sentence:
"$GPGSV,2,1,08,12,76,358,,09,51,120,,30,50,274,,27,42,122,*75\x0d\x0a"
gpsd: GPS on /dev/rfcomm0 is offline (0.000094 sec since data)
^Cgpsd: received terminating signal 2.
gpsd: closing GPS=/dev/rfcomm0 (5)
gpsd: exiting.

In a GSV sentence, an empty SNR field should be interpreted as zero.

Cheers,
