Re: [gpsd-users] Does GPSD compatible with novAtel gps receiver (FlexFak 6)?

[Shengrong Yin]

I try to set the output mode as NMEA with following command.

gpsctl -f -n /dev/ttyUSB0

Most of the time, it gives me the following output:

gpsctl:SHOUT: vendor/product match with 091e:0003 not found
gpsctl:ERROR: packet recognition timed out.

There is one time, it gives me this:

$ gpsctl -f -n /dev/ttyUSB0
gpsctl:SHOUT: vendor/product match with 091e:0003 not found
gpsctl:SHOUT: /dev/ttyUSB0 identified as a SiRF binary at 4800.
gpsctl:SHOUT: switching to mode NMEA.
Then I can see some output from /ttyUSB0.
$ cat /dev/ttyUSB0
$GPGGA, ...

It is the same problem as described in the following link:

http://astrobeano.blogspot.com/2012/10/pharosmicrosoft-gps-360-on-raspberry-pi.html

Why the switching is not working stably, and most of the time it keeps telling me

packet recognition timed out.

PS. the novAtel gps can be recognized as a general usb device. The following is

from the dmesg command.

As Gary says, it should work in NMEA mode. I've never had my hands on this hardware, so I haven't written a driver for its binary protocol. The last NovAtel device I worked with was an AC12.

Wow, that looks very nice. 3 bands!  How much does it cost?

Never heard of it before.  The web page does not say what type of
serial output it sends.  Do you have a link to documentation on it?

GDB has a 'break' feature; why doesn't it have 'fix' too?
