Kroz ovaj tekst naučit ćete kako spojiti i podesiti vanjsku GPS senzor putem bluetootha na Linuxu.

Upozorenje

Bez ovih uređaja ne možete proći ovaj vodič.

Da biste prošli kroz ovaj vodič potrebano vam je računalo bilo s ugrađenim bluetooth čipom bilo s vanjskim usb bluetooth stickom i GPS senzor s mogućnošću povezivanja putem bluetootha.

Cijene GPS uređaja drastično padaju zadnjih godina te su sada cijene prihvatljive i za sve one kojima do prije koju godinu nisu bili dokučivi. Danas se bluetooth stick može dobiti već za 55kn dok se cijene GPS bluetooth dongle kreću oko 500kn, najbolje da sami pogletate aktualne cijene. Preporuka je uzeti GPS senzor s SiRF Star III čipom koji provjereno dobro radi.

If you have bluetooth GPS dongle that you have laying around, or can borrow one from somebody, and would use GPS on Fedora laptop while you are driving a bike or a car around then this is the guide for you.

Here are some images of bluetooth dongles if you haven't seen them before.


You can check with hcitool command that you have bluetooth device and that it is working correctly :

hcitool dev


Then let’s make sure you have bluetooth service running:

service bluetooth status


if it is not running just start it with:

service bluetooth start


Turn on your bluetooth GPS dongle and find its bluetooth mac address with hcitool command:

hcitool scan
Scanning …
00:1E:EE:00:11:22 LG KU990
00:02:78:99:FF:00 SJ GPS
00:12:EE:55:00:FF Device01


If you find more than one bluetooth device you should know the name of your GPS dongle. My GPS dongle has a “GPS” in its name so it is easy to spot its mac address: 00:02:78:99:FF:00 (SJ GPS)


You need to install gpsd and setup bluetooth config files, so let’s first install gpsd:

su -
yum install gpsd gpsd-clients -y


Then you need to edit bluetooth config file so that gpsd connects automatically to GPS bluetooth dongle.

<code>gedit -etc/bluetooth/rfcomm.conf


and add these lines:

rfcomm0 {
# Automatically bind the device at startup
bind yes;

# Bluetooth address of the device
device 00:12:EE:55:00:FF;

# RFCOMM channel for the connection
channel 1;

# Description of the connection
comment “GPS Bluetooth dongle”;
}


After reboot check if you have /dev/rfcomm0 device with:

ls -al /dev/rfcomm0


If after reboot (or you don’t wan’t to reboot) you still don’t have /dev/rfcomm0 then just issue this command:

rfcomm bind rfcomm0


Now start gpsd daemon:

gpsd /dev/rfcomm0


Now you can start having fun! :)


Install gps applications like tangogps, gpsdrive and gpsbabel:

yum install tangogps gpsdrive gpsbabel
