GPS receiver connexion problem with display

Gian-Piero · November 2, 2012, 2:31pm

I am running openSUSE 12.2 x86_64.
I have connected a Navilock NL-402U gps receiver.
I have installed the following : gpsd (version 3.5-2.1.2) , gpsd-clients, gpsd-devel, libgps20 and** python-gpsd** included in the openSUSE 12.2 distribution.
I have started gpsd with the following command :
sudo /usr/sbin/gpsd -F /dev/ttyACM0
The process ID is running as given by ps -C gpsd.

lsusb gives :
Bus 002 Device 002: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Bus 005 Device 002: ID 046d:c517 Logitech, Inc. LX710 Cordless Desktop Laser

In the output of dmesg:
** 1511.497014] usb 6-1: new full-speed USB device number 2 using uhci_hcd

1511.754104] usbcore: registered new interface driver cdc_acm**

When launching xgps, I get :
** (process:8142): WARNING **: Trying to register gtype ‘GMountMountFlags’ as enum when in fact it is of type ‘GFlags’

** (process:8142): WARNING **: Trying to register gtype ‘GDriveStartFlags’ as enum when in fact it is of type ‘GFlags’

** (process:8142): WARNING **: Trying to register gtype ‘GSocketMsgFlags’ as enum when in fact it is of type ‘Gflags’

The window of xgps opens but there is no communication with gpsd.

As I am not a specialist, I do not know what to do.
Any help would be greatly appriciated.

Hi
Have you seen this one?
http://forums.opensuse.org/opensuseforums/english/get-technical-help-here/hardware/414389-usb-gps-mini-howto.html

A forum search on gpsd turns up other posts as well.

Yes, thank you, but it did not help me!

Hi
Looks like it needs a udev rule…
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=650774

Do gps type rules exist in /lib/udev/rules.d or /etc/udev/rules.d?

Not sure about the driver loaded either as CDC_ACM is for a modem
device…

Thank you for your answer.

Do gps type rules exist in /lib/udev/rules.d or /etc/udev/rules.d?

Yes, the file 51-gpsd.rules was automatically created in /lib/udev/rules.d.
Its contents is:

SUBSYSTEM != “tty”, GOTO=“gpsd_end”

ACTION != “remove, GOTO=“gpsd_add”
KERNEL==“ttyUSB*”, RUN=”/lib/udev/gpsd.sh"

LABEL=“gpsd_add”
ACTION != “add”, GOTO=“gpsd_end”

“Prolific Technology 2303 (commonly in tandem with SiRF chips)”

KERNEL==“ttyUSB*”, ATTR{idVendor}==“10c4”, ATTR{idProduct}==“ea60”, RUN="/lib/udev/gpsd.sh"

LABEL=“gpsd_end”

Not sure about the driver loaded either as CDC_ACM is for a modem device…

According to the manufacturer, the u-blox’ USB interface implements Communication Device Class.
The gpsd interface is loaded by:

/usr/sbin/gpsd -F /dev/ttyACM0

I have also added the following two line in the 51-gpsd.rules, corresponding to my gps receiver

# u-blox AG, u-blox 5 (tested with Navilock NL-402U) (linux module: cdc_acm)
KERNEL=="ttyUSB*", ATTR{idVendor}=="1546", ATTR{idProduct}=="01a5", RUN="/lib/udev/gpsd.sh"

Is it correct?

Hi
Give it a try, would also be interested in the dmesg output, also run
the command (as root user) before plugging the device in to see the
output.


udevadm monitor

When plugging the device, the output is:

Hi
In the udev rule does /lib/udev/gpsd.hotplug exist at the bottom of the file?

If so, then change your rule to;


# u-blox AG, u-blox 5 (tested with Navilock NL-402U) [linux module: cdc_acm]
ATTRS{idVendor}=="1546", ATTRS{idProduct}=="01a5", SYMLINK="gps%n", RUN+="/lib/udev/gpsd.hotplug"

Gian-Piero · November 4, 2012, 12:05pm

In the udev rule does /lib/udev/gpsd.hotplug exist at the bottom of the file?

No, there is only a gpsd.sh file

Gian-Piero · November 4, 2012, 12:27pm

I have also tried the following commands:

gpsd -N -D3 -F /dev/ttyACM0

gpsd:INFO: launching (Version 3.5)
gpsd:ERROR: can’t bind to IPv6 port gpsd, Cannot assign requested address
gpsd:INFO: listening on port gpsd

gpsd:INFO: running with effective user ID 65534
gpsd:INFO: startup at 2012-11-04T11:07:51.000Z (1352027271)

then exiting with ^C:

^Cgpsd:WARN: received terminating signal 2.
gpsd:WARN: exiting.

And, when gpsd is running, in another terminal:

lsof | grep ttyACM0

lsof: WARNING: can’t stat() fuse.gvfs-fuse-daemon file system /run/user/piantino/gvfs
Output information may be incomplete.
gpsd 4408 nobody 3u unix 0xffff8800b4687500 0t0 22714 /dev/ttyACM0

Do these information help?

Another try:
In the first terminal:

gpsd -N -n -F /var/run/gpsd.sock -D 5

Output of terminal 1:

then in terminal 2:
