This allows you to use your Maemo device to use [[Bluetooth]] PAN to connect via another device to another 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.

If you have [[Nokia N900]] you may instead use it as PAN server to allow an other device such as a Nokia N8x0 to utilize Bluetooth PAN.

== Installing ==

For the [[Nokia N900]] pan is disabled by default.
To enable it, edit /etc/bluetooth/main.conf and remove ''network'' from the disabled plugins
 [General]
 # List of plugins that should not be loaded on bluetoothd startup
 DisablePlugins = <s>network</s>,input,hal
''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!

==Sharing your connection over bluetooth [n900]==

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.
TODO: when no internet connection is active ask to set it up

=== Using PAN on older maemo5 pr3 ===
In terminal cd /etc/udev/ then write vi bluenet.sh
it will open 
/etc/udev/bluenet.sh press R and paste that code:
 #!/bin/sh
 if [ $ACTION = "add" ]; then 
 # by 9000 @ talk.maemo.org
 # Prompt you to select the Internet connection. You may choose gprs or wifi
 run-standalone.sh dbus-send --system --type=method_call --dest=com.nokia.icd_ui /com/nokia/icd_ui com.nokia.icd_u
 # Selecting and establishing connection takes time

 set -x

 NETMASK="255.255.255.0"
 DHCP_RANGE="192.168.3.60,192.168.3.70"
 RUNFILE="/var/run/btpan_tethering.pid"
 DNSMASQ="/usr/sbin/dnsmasq"
 # Load modules
 modprobe ipt_MASQUERADE
 # flush old rules
 iptables -F
 iptables -t nat -F
 iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
 # forward IPs
 echo 1 > /proc/sys/net/ipv4/ip_forward
 # Setup bnep0
 ifconfig bnep0 down
 ifconfig bnep0 up
 ifconfig bnep0 $IP_ADDR netmask $NETMASK up
 # Setup DNS and DHCP
 start-stop-daemon -S -p $RUNFILE -m -b -x $DNSMASQ -- -k -I lo -z -a $IP_ADDR -F $DHCP_RANGE -b
 run-standalone.sh dbus-send --type=method_call --dest=org.freedesktop.Notifications /org/freedesktop/Notifications org.freedesktop.Notifications.SystemNoteInfoprint string:'Bluetooth PAN Activated'
 fi

press esc, then :w to save file and :q to quit

set ''/etc/udev/bluenet.sh'' as executible:
 chmod +x /etc/udev/bluenet.sh

cd /etc/udev/rules.d/ 
command vi 98-bnep0.rules and press R

/etc/udev/rules.d/98-bnep0.rules copy that txt and paste it, esc and Save it with command :w quit vi editor :q :
 ACTION=="add", SUBSYSTEM=="net",  KERNEL=="bnep0", RUN+="/etc/udev/bluenet.sh"

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 PAN profile.

It is better to compile binaries in scratchbox. See [[Documentation/Maemo 5 Final SDK Installation]]

To be able to copy files from scratchbox to your N900 you should install rsync and make sure you can copy files to your phone.

Compile bluetooth stack utilities:
 apt-get source bluez
 apt-get build-dep bluez
 apt-get --build source bluez
Copy pand binary to your device:
 rsync -av bluez-4.60/debian/bluez-test/usr/bin/pand n900:/usr/local/bin/

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 -nc <bdaddr>
List connections:
 pand -l
Remove connection:
 pand -k <bdaddr>
