[gpsd-users] Make gpsd work with BU-353 S4 receiver

[Benjamin Armbruster]

Hi!

I've found that gpsd does not provide a stable FIX when using the SiRF binary 
mode.
This can be observed using xgps. You will notice that the FIX will be lost over 
and
over again. This is worthless for navigation. However, using NMEA works like a 
charm.

To switch to NMEA, one has to issue the following commands:


1. stty -F /dev/ttyUSB0 ispeed 4800

2. xgps (or e.g. monav, but for testing purposes, use xgps)

3. gpsctl -n /dev/ttyUSB0 (switch device to NMEA). It will complain, that the 
action
has failed, but do not worry!

4. By now, the device should be switched to NMEA and a constant FIX
should be monitorable with xgps. You could also invoke cat /dev/ttyUSB0 to make
sure, you are using NMEA and not SiRF binary.


So what can be done here? Make gpsd use the NMEA protocol by default when 
detecting
this gps unit!

I hope I could be of any help. If you have any questions, just ask.

Below, you will find the output of gpsd when running it withozt the above 
workaround.
