Personal Area Networking Profile of Bluetooth protocol allows you to connect your Maemo device via another device to another network such as the Internet.
+
This allows you to use your Maemo device to use [[Bluetooth]] PAN to connect via an other device to an other network such as the Internet.
The Connection manager is used for this purpose, exactly the same way as you connect to a WLAN network or to a cell phone dial-up connection ([[Bluetooth DUN]]). Most Windows Smartphones use this method of connection when used as a modem via Bluetooth.

NAP stands for Network Access Point. It's a PAN profile for serving incoming connections.

For the [[Nokia N900]] pan is disabled by default.
+
Install maemo-pan through the Application manager. You may need to restart your tablet after installation in order to force a dependency on maemo-pan (libicd-network-dummy package) being loaded.
-
To enable it, edit /etc/bluetooth/main.conf and remove ''network'' from the disabled plugins

-
''libicd-network-null'' is also recommended for using internet over bluetooth

apt-get install libicd-network-null

For other devices you need to install maemo-pan through the Application manager. You may need to restart your tablet after installation in order to force a dependency on maemo-pan (libicd-network-dummy package) being loaded.

Tap on the Connectivity icon in your status bar and either "Select a connection" or "Change connection" to see a list of available network access points. You should see one called "Dummy Network" (this name will likely change in future versions of maemo-pan, see [https://bugs.maemo.org/show_bug.cgi?id=3306 bug #3306] for details).

To connect to the Internet through this connection you must make sure the "Internet Connection Sharing" application is running on your phone and has a connection. Select the "Dummy Network" from the tablet network list and enjoy anywhere Internet!

Using [http://maemo.org/packages/view/genwall genwall] for internet connection sharing over bluetooth, follow:([http://talk.maemo.org/showpost.php?p=1454885&postcount=62 Linux]/[http://talk.maemo.org/showpost.php?p=1454885&postcount=63 Windows]).

Using udev to automatically setup internet connection sharing over bluetooth comes now.

A kernel with iptables support is needed,
+
-
 
+
-
[[Kernel Power]] is the recommended way to achieve this. see [[Kernel Power]] for installation details.
+
-
 
+
-
The default kernel with [[Community_SSU/Thumb|CSSU-thumb]] is also suitable.
+
-
 
+
-
 
+
-
Install the ''iptables'' package:
+
-
apt-get install iptables
+
-
 
+
-
create the following 2 files:
+
-
 
+
-
/etc/udev/rules.d/98-bnep0.rules:
+
-
ACTION=="add", SUBSYSTEM=="net",  KERNEL=="bnep0", RUN+="/etc/udev/bluenet.sh"
+
-
ACTION=="remove", SUBSYSTEM=="net",  KERNEL=="bnep0", RUN+="/etc/udev/bluenet.sh"
+
-
 
+
-
/etc/udev/bluenet.sh:
+
-
#! /bin/sh
+
-
if [ $ACTION = "add" ]; then
+
-
echo 1 > /proc/sys/net/ipv4/ip_forward
+
-
iptables -t nat -A POSTROUTING ! -o lo -j MASQUERADE
+
-
ifconfig bnep0 192.168.3.1
+
-
ifconfig bnep0 up
+
-
/usr/sbin/dnsmasq -I lo -z -a 192.168.3.1 -F 192.168.3.64,192.168.3.127 -x /var/run/dnsmasq.pid.bnep0
+
-
else
+
-
iptables -t nat -D POSTROUTING ! -o lo -j MASQUERADE
+
-
if [ -f /var/run/dnsmasq.pid.bnep0 ]; then
+
-
DNSMASQ_PID=`cat /var/run/dnsmasq.pid.bnep0`
+
-
rm -f /var/run/dnsmasq.pid.bnep0
+
-
kill $DNSMASQ_PID
+
-
        fi
+
-
fi
+
-
then set ''/etc/udev/bluenet.sh'' as executible:
+
-
chmod +x /etc/udev/bluenet.sh
+
-
 
+
-
now whenever an authorised remote device makes a bluetooth pan (nap) connection iptables and dnsmasq are setup to allow that device access to the phones network.

It is possible to use PAN to share Internet connections via PAN between two Nokia devices. However, on older devices it is recommended to use [[Bluetooth DUN]] (dial-up networking), since this is the normal method which smartphones use to share Internet access over Bluetooth.

== Bluetooth PANU ==
 
-
 
-
PANU is a client role for the PAN profile. Here's the way how to make it work.
 
-
 
-
Install bluez-test from SDK tools repository:
 
-
echo 'deb http://repository.maemo.org/ fremantle/tools free non-free' >> /etc/apt/sources.list
 
-
apt-get install bluez-test
 
-
 
-
You may now remove or comment SDK repository:
 
-
perl -pi -e 's,^(deb http://repository.maemo.org/ fremantle/tools .*)$,#\1,' /etc/apt/sources.list
 
-
 
-
And now you can use your N900 device as a bluetooth networking client. Below are some commands.
 
-
 
-
Connect to another bluetooth device that provides NAP service:
 
-
pand -c <bdaddr>
 
-
List connections:
 
-
pand -l
 
-
Remove connection:
 
-
pand -k <bdaddr>
 
-
