and now to test the bluetooth:

 hcitool scan

this should return a list of devices like:

        00:16:4E:D7:AE:5F       Nokia N70
        00:12:62:AF:C0:6E       Nino
        00:11:67:80:41:96       BT-GPS

Step 2

With the bluetooth we need to create a serial connection between our GPS device and the computer

to do this we first need some information on the device; the MAC code and the serial port.

do a

 hcitool scan

and take the MAC address of the GPS unit in my case:
 00:16:4E7:AE:5F Nokia N70
 00:12:62:AF:C0:6E Nino
 00:11:67:80:41:96 BT-GPS

so i want: 00:11:67:80:41:96

to get the serial port do

 sdptool browse 00:11:67:80:41:96

which will return

 Browsing 00:11:67:80:41:96 ...
 Service Name: Bluetooth Serial Port
 Service RecHandle: 0x10007
 Service Class ID List:
  "Serial Port" (0x1101)
 Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 1
 Language Base Attr List:
  code_ISO639: 0x656e
  encoding:    0x6a
  base_offset: 0x100
 Profile Descriptor List:
  "Serial Port" (0x1101)
    Version: 0x0100

the channel we want is 1

now create a file in /etc/bluetooth/ called rfcomm

 sudo gedit /etc/bluetooth/rfcomm.conf

adding an entry:

 rfcomm4 {
        bind yes;
        device < GPS MAC ADDRESS>;
        channel 1;
        comment "Serial Port";
        }
to start using the GPS type:

 rfcomm connect 4

if for some reason you get

"Can't create RFCOMM TTY: Address already in use"

do:

 sudo rfcomm release 4

again followed by

 rfcomm connect 4

that should display:

 nino@laptop:~$ rfcomm connect 4
 Connected /dev/rfcomm4 to 00:11:67:80:41:96 on channel 1
 Press CTRL-C for hangup

any GPS software you are gonna use will make use of the /dev/rfcomm4

Step 3

Now to test the GPS install the GPS utils


 sudo apt-get install gpsd-clients
 sudo apt-get install gpsd

the GPSD is the daemon for the GPS reciever so we want to bind the service with the device:


 gpsd /dev/rfcomm4

and finally to see if were getting any information from the GPS device run


 xgps
