3.Enter the following command to edit the bluetooth configuration file.After making changes save the file....

itsme@itsme-laptop:~$ sudo gedit /etc/bluetooth/rfcomm.conf
#
# RFCOMM configuration file.
#

#rfcomm0 {
#    # Automatically bind the device at startup
bind yes;
#itsme@itsme-laptop:~$ sudo gedit /etc/bluetooth/rfcomm.conf

#    # Bluetooth address of the device
device
44:4E:1A:B3:75:EF;                    //copy the mac address of your device here
#
#    # RFCOMM channel for the connection
channel    3;                        //copy the channel number here
#
#    # Description of the connection
comment "Dial-Up Networking";                //put your own description of the connection
#}

4.Now we have to edit the wvdial.conf file for dialing up(note:if there is no such file you've to create one)

itsme@itsme-laptop:~$ sudo gedit /etc/wvdial.conf
[Dialer Defaults]
Init = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,"IP","TATA.DOCOMO.INTERNET"        //here my access point is TATA.DOCOMO.INTERNET.... if you are using a different one... ask your
Modem = /dev/rfcomm0                    //service provider
Phone = *99***1#                    //this is the dial number for tata docomo... if different as your service provider
Username = ''                        //tata docomo does not requires username and password,i don't know about other networks
Password = ''
New PPPD = yes
ISDN = no
BAUD = 115200
Stupid Mode = yes
Carrier Check = yes
Auto Reconnect = yes
lcp-echo-interval = 30
lcp-echo-failure = 4

5.All the steps are completed.Now we've to bind our bluetooth device with the system.

itsme@itsme-laptop:~$ sudo rfcomm bind 0 44:4E:1A:B3:75:EF 3         //here give your device's mac address and channel number.

6.Dialing.... (you have to accept the connection through phone.... it'll ask for DUN connection(Dial-UP Network))

itsme@itsme-laptop:~$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ

7.now your system is connected to the internet.

8.If you encounter any problem you 've to edit a file.Move to the directory  /etc/peers/options
comment the line

# lcp-echo-intervel = 10

and another line

# lcp-echo-failure = 4
