[gpsd-users] gpsd 3.12 cgps 3.12 - time out with NL-402U

Hash: SHA1

Greetings,

I have build and installed 3.12 from
http://download-mirror.savannah.gnu.org/releases/gpsd/gpsd-3.12.tar.gz
The issue I had before with the old version of gpsd shipped with
ubuntu 12.04 persists with the new version.

Problem description:

- - start gpsd (gpsd -n -b -N -D 5 /dev/ttyACM0)
- - plug NL-402U (without fix)
- - start cgps
- - _cgps has a time out_

alternativ:

- - don't start gpsd
- - plug NL-402U (without fix)
- - gpsd gets started by udev rules (or something, I don't really know)
- - start cgps
- - _cgps has a time out_

expected behaiviour:

cgps recognizes a device and reports it.

For some logs see below.
I aslo added a screenshot what cgps looks like before it timesout a
second later.

Regards,
Philipp

cgps output:

:~$ cgps
cgps: GPS timeout

gpsd log:

:~$ sudo gpsd -D 5 -N -n /dev/ttyACM0 2>&1 | tee gpsd.log
