Here’s a mini HOWTO explaining how Airtel GPRS users can connect their linux boxes to the net using only a bluetooth connection from their phone. That’s right, no data cable required!

NOTE: I’ve only tried this on Debian but it should work fine on just about any distro.. use your distro’s package management tool instead of apt.

Follow these steps:

1. First make sure GPRS (Mobile Office) is enabled on your phone. This won’t work with Airtel Live :P

2. Install the Bluetooth utilities:

sudo apt-get install bluez-gnome bluez-utils

3. Find the MAC address of your phone:

hcitool scan

The output should be something like this:

Scanning ...
00:19:63:74:XX:YY saurav

Write down this address somewhere for future reference.

4. Now, determine the channel used for dial up networking using the MAC you just found:

sdptool browse 00:19:63:74:XX:YY

...
Service Name: Dial-up Networking
Service RecHandle: 0×10001
Service Class ID List:
“Dialup Networking” (0×1103)
“Generic Networking” (0×1201)
Protocol Descriptor List:
“L2CAP” (0×0100)
“RFCOMM” (0×0003)
Channel: 1
Profile Descriptor List:
“Dialup Networking” (0×1103)
Version: 0×0100

In this case, the required channel is channel no. 1. This will be used to configure the bluetooth connection.

5. Open up /etc/bluetooth/rfcomm.conf with your favorite editor.

sudo nano -w /etc/bluetooth/rfcomm.conf

Make it look something like this (replace with your MAC address and channel):

rfcomm0 {
bind yes;
device 00:19:63:74:XX:YY;
channel 1;
comment “Dial-up Networking”;
}

6. Next, restart bluetooth services:

sudo...
