Lenovo ThinkPad GPS module

Hi.
I'm trying to access to my build-in GPS module in Lenovo E320 laptop (Ericsson F3507g). But I can't see the device in /dev/. Do I need any driver to be installed / loaded?

Thanks.

Scanning your serial ports for a modem.

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

Re: Lenovo ThinkPad GPS module

I don't know which driver your gps uses but you will need a running gpsd first:

pacman -S gpsd

If you're using systemd run

systemctl start gpsd.service

In a terminal run

tail -f /var/log/messages.log

Turn on your gps if it isn't already on; it should tell you something like this:

Aug  2 15:22:06 localhost kernel: [16305.571776] usb 6-1: new full-speed USB device number 
6 using uhci_hcd
Aug  2 15:22:06 localhost kernel: [16305.724346] pl2303 6-1:1.0: pl2303 converter detected
Aug  2 15:22:06 localhost kernel: [16305.736432] usb 6-1: pl2303 converter now attached to 
ttyUSB0
Aug  2 15:22:06 localhost mtp-probe: checking bus 6, device 6: 
"/sys/devices/pci0000:00/0000:00:1d.0/usb6/6-1"
Aug  2 15:22:06 localhost mtp-probe: bus: 6, device: 6 was not an MTP device
Aug  2 15:22:06 localhost gpsd.hotplug: add /dev/ttyUSB0
Aug  2 15:22:06 localhost gpsdctl: reached a running gpsd

Of course you may have a different driver - mine is pl2303 and is loaded automatically.
Good luck!
Edit: You should be good to go. Check that you are receiving satellite data by running xgps which is included with gpsd.

Re: Lenovo ThinkPad GPS module

I must connect to a modem first to use GPS module. I've followed these instructions http://www.tjansson.dk/?p=450 and inserted SIM card as described, but I don't have any /dev/ttyACM*. Do I need to load some driver to use this modem?

Re: Lenovo ThinkPad GPS module

Is there a kill switch for the modem? Any relevant boot time messages?
