Mobile Broadband Bluetooth Dialup Networking in Ubuntu 8.04

Turn on bluetooth on your phone and Computer/Laptop.If you’ve already tried connecting them before, delete any reference to your bluetooth phone’s ID from your computer. To do this, type Alt+F2 and then type the following :

gksudo nautilus /var/lib/bluetooth/

( Enter password to give permission )

Now delete all files/folders there. Then turn off & then turn on computer’s bluetooth device. Then scan bluetooth device from your phone and add your computer as paired device.

( Enter the same pass code in both phone and computer. )

Now find the MAC address of your phone by typing the following command :

hcitool scan

Copy the MAC address. It looks like XX:XX:XX:XX:XX:XX

Now we need to find out what channel to connect to. For this type the following command :

sdptool browse XX:XX:XX:XX:XX:XX

( XX:XX:XX:XX:XX:XX <– This is your phone’s MAC address here )

In my case it looks like

siddhartha@ubuntu:~$ hcitool scan
