It seems that getting an internet connection in the center of Bucharest is a complicated now as ever so the gprs connection to my phone which I pay and almost never used came to mind as an idea. Not really usable for internet but not to remain completely disconnected.
So here is a short guide to connect to internet using bluetooth and my T630 phone for a GPRS Vodafone connection.
Bluetooth
Find the mac of the phone
#hcitool scan<br></br>Scanning ...<br></br> 00:0F:D5:7B:XX:XX T630
List the services
#sdptool browse 00:0F:D5:7B:XX:XX <br></br>Browsing 00:0F:D5:7B:XX:XX ...<br></br>Service Name: Dial-up Networking<br></br>Service RecHandle: 0x10000<br></br>Service Class ID List:<br></br> "Dialup Networking" (0x1103)<br></br> "Generic Networking" (0x1201)<br></br>Protocol Descriptor List:<br></br> "L2CAP" (0x0100)<br></br> "RFCOMM" (0x0003)<br></br> Channel: 1<br></br>Profile Descriptor List:<br></br> "Dialup Networking" (0x1103)<br></br> Version: 0x0100<br></br><br></br>Service Name: Voice gateway<br></br>Service RecHandle: 0x10002<br></br>Service Class ID List:<br></br> "Headset Audio Gateway" (0x1112)<br></br> "Generic Audio" (0x1203)<br></br>Protocol Descriptor List:<br></br> "L2CAP" (0x0100)<br></br> "RFCOMM" (0x0003)<br></br> Channel: 3<br></br>Profile Descriptor List:<br></br> "Headset" (0x1108)<br></br> Version: 0x0100<br></br>....<br></br>
Configure the bluetooth com port
#cat /etc/bluetooth/rfcomm.conf<br></br><br></br>rfcomm1 {<br></br> bind yes;<br></br> device 00:0F:DE:CB:59:EE;<br></br> channel 1;<br></br> comment "Dial-up Networking";<br></br>}<br></br>
Restart bluetooth service
/etc/init.d/bluetooth restart<br></br>
PPPD configuration
The /etc/ppp/peers/gprs
file:
