<div>= Setting up Debian for Tethering =<br />
<br />
How to setup the N900 is described here [[Bluetooth_DUN]]<br />
<br />
== Setup bluetooth connectivity ==<br />
<br />
=== Installing required Debian packages ===<br />
<br />
apt-get install bluez-utils pppconfig<br />
<br />

Search for the ''Dial-Up Networking service''<br />

Add an rfcomm device (e.g. rfcomm0) to /etc/bluetooth/rfcomm.conf (make sure to replace the bluetooth device address 11:22:33:44:55:66 with the bluetooth device address of your N900):<br />
<br />
/etc/bluetooth/rfcomm.conf<br />
rfcomm0 {<br />
# # Automatically bind the device at startup<br />
bind yes;<br />
#<br />
# # Bluetooth address of the device<br />
device 11:22:33:44:55:66;<br />
#<br />
# # RFCOMM channel for the connection (whatever you get from the sdptool output)<br />
channel 1;<br />
#<br />
# # Description of the connection<br />
comment "N900";<br />
}<br />
<br />
Restart the bluetooth stack:<br />
<br />
blackbox:~# /etc/init.d/bluetooth restart<br />
<br />
For bluetooth pairing you can run<br />
<br />
blackbox:~# cat < /dev/rfcomm0<br />
<br />
and first the n900 then the Debian system should ask you for a 4 digit PIN which you define on the n900 and confirm on the Debian system. You might have to configure the helper application which is using the PIN in /etc/bluetooth/hcid.conf<br />
<br />
=== Dial-Up Settings ===<br />
<br />
Run pppconfig and use /dev/rfcomm0 as modem interface:<br />
<br />
In my settings for klarmobil (Germany) I manually added two lines (at+cdgcont=... and AT+CREG...):<br />
<br />
blackbox:~# cat /etc/chatscripts/klarmobil<br />
# This chatfile was generated by pppconfig 2.3.18.<br />
# Please do not delete any of the comments. Pppconfig needs them.<br />

In my peers file I changed the baud rate to the device<br />
<br />
blackbox:~# cat /etc/ppp/peers/klarmobil<br />
# This optionfile was generated by pppconfig 2.3.18.<br />
