GPRS Internet with your nokia and pppd and bluetooth

Heres some tips on how i got my Nokia n93i to allow me to borrow it's GPRS internet connection via Three Australia.

Using my debian/lenny linux laptop on 2.6.24

1. Setup your rfcomm bluetooth interface

This is my /etc/bluetooth/rfcomm.conf file (also attached)
Replace your device mac address with which ever is the device address of your mobile phone..

# hcitool scan
Scanning ...
        00:xx:xx:xx:xx:xx       dgtlmoon

So in your rfcomm.conf put this..

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

        # Bluetooth address of the device
        device 00:xx:xx:xx:xx:xx;

        # RFCOMM channel for the connection
        channel 1;

        # Description of the connection
        comment "PPPD connect";
}

Create the PPPD scripts

in /etc/ppp/peers/bluetoothconf

debug
noauth
connect "/usr/sbin/chat -v -f /etc/chatscripts/bluetoothconn"
usepeerdns
/dev/rfcomm0 115200
defaultroute
crtscts
lcp-echo-failure 0

and your /etc/chatscripts/bluetoothconn should look like this..

TIMEOUT 35
ECHO    ON
ABORT   'nBUSYr'
ABORT   'nERRORr'
ABORT   'nNO ANSWERr'
ABORT   'nNO CARRIERr'
ABORT   'nNO DIALTONEr'
ABORT   'nRINGINGrnrnRINGINGr'
''      rAT
OK      'AT+CGDCONT=,,"3netaccess";'
OK      ATD*99***1#
}      ""

the 3netaccess is some kind of packet-interface filter name, you can find this out by going to Tools -> Settings -> Connection -> Access Points -> Mobile Internet and putting in what is set for "Access point name"

Launching the connection

Once this is complete, it should be as easy as running

pon bluetoothconn

You should see in /var/log/messages

Should be as easy as that, now just because of your telcos dodgey pricing schemes for mobile internet usage!
