[gpsd-users] gpsd will not work with WBT-201 - gpsmon does

[address@hidden]

Hi!

I would like to request some major help with my gpsd on raspi. It will not work 
in any way. 
I don't have any idea on how to continue (gpsmon works, gpsd not).

        gpsd -N -D8 -F /var/run/gpsd.sock /dev/ttyUSB0

from the helpfiles will also not work. Starting the Daemon with "gpsd -S 2947 
/dev/ttyUSB0 -F /var/run/gpsd.sock" results in:

        gpsd 1137 0.1 0.3 7128 3112 ? S<s 01:31 0:00 gpsd -S 2974 /dev/ttyUSB0 
-F /var/run/gpsd.sock (no syslog entry)

But if I start cgps I receive some syslog entrys (directly after "cgps":

        Dec 4 01:31:50 raspi systemd[1]: Started GPS (Global Positioning 
System) Daemon. 
        Dec 4 01:31:50 raspi gpsd[1141]: gpsd:ERROR: device open of ttyUSB0 
failed: No such file or directory - retrying read-only 
        Dec 4 01:31:50 raspi gpsd[1141]: gpsd:ERROR: read-only device open of 
ttyUSB0 failed: No such file or directory

failed. 
        Dec 4 01:31:50 raspi gpsd[1141]: gpsd:ERROR: ttyUSB0: activation 
failed, freeing device 

it starts a new daemon:

        gpsd 1137 0.0 0.3 7128 3112 ? S<s 01:31 0:00 gpsd -S 2974 /dev/ttyUSB0

ttyUSB0

But no data is received.

gpsmon instead works perfectly:

This is the logfile from gpsmon:

        (but dmesg | grep USB shows:
                usb 1-1.5: cp210x converter now attached to ttyUSB0)

I hope you have some tips for me...
