How to Use Internet Over Mobile Phone
General
This page describes how you can connect your Computer with your mobile phone using bluetooth to get an internet connection.
If you cannot get a GPRS Connection from your mobile phone yet, it most likely won't work with your computer as well, get it work with your phone alone before attempting to get it with computer. Hint: Call your ISP, they'll send you the configuration for your phone if you ask them.
Linux
Get a root shell
sudo bash
or
su -
Check if everything is in place
updatedb # generates index of files on disk locate pppd # searches that index for pppd (there should be one in: /usr/sbin) locate rfcomm # in /usr/bin
if any of theese commands are unfamiliar to you, read the DESCRIPTION part of the man page (try "apropos ppp" or "man pppd")
If theese are not in place use apt or emerge (depending on distribution) to find and get them. The packages on ubuntu are:
bluez-utils libbluetooth2
"hciconfig" should show like this:
hci0: Type: USB
BD Address: 00:1E:37:E6:3F:62 ACL MTU: 1017:8 SCO MTU: 64:8
UP RUNNING PSCAN ISCAN
RX bytes:9298 acl:42 sco:0 events:94 errors:0
TX bytes:1333 acl:31 sco:0 commands:43 errors:0
IF NOT: your bluetooth device is not up and running, try switching off and on again. If that does not help: search "howto bluetooth linux" and your machine name (e.G. "HP 2510p").
"hcitool scan" should show like this:
Scanning ...
00:17:B0:40:29:18 Ben Mobile
IF NOT: your computer does not detect your mobile. Try switching the bluetooth of your computer and mobile off and on again, then test again. If that does not help search: "howto bluetooth linux mobile" and your machine and mobile name.
setting up config files
/etc/ppp/peers/gprs

Explantation
/dev/rfcomm0 is the channel that rfcomm listens to. 115200 the connection speed. (115200 bits/sec)
/usr/sbin/chat is the protocoll to use (chat) /etc/chatscripts/gprs references the config for that chat.
/etc/chatscripts/gprs

Explantations
"internet.eplus.de" has to be changed for your ISP. There is a list at the bottom of the page #List Of ISP Specific Data
Last steps
open 2 shells, get root in both of them: first:
rfcomm connect 0 00:17:B0:40:29:18
second:
pon gprs route del default gw route add default gw 10.6.6.6
Explantations
- rfcomm opens the bluetooth connection. 00:17:B0:40:29:18 is the address of my phone, yours is different!
- pon opens a ppp connection (the file /etc/ppp/peers/'gprs' is the config for it
- route del default gw removes the old gateway adress (if any)
- route add default gw 10.6.6.6 sets the new one
10.6.6.6 is the gateway of my isp, lookup yours below or do
ifconfig ppp0
and use the 'P-t-P:' value found there
Done
Knows Problems
- The connection has to be established manually
- The default route won't be set automagically
