Hello guys, just wanted to share how setup bluetooth under my slackware 13.37.
The objective of this post is to connect a device via bluetooth, a phone or broadband modem, to connect to the internet. It's a little bit techy but it gets the job done.I will try to make it easy on you guys.
You might also refer to http://slackwiki.org/Bluetooth as it is complete.

<note important>I'm on IBM Thinkpad R61i,
Slackware 13.37,
Kernel 2.6.37.</note>

To summarize what I did,

Install bluez subsystem.

Create bluetooth ON/OFF switch

Since my internal bluetooth device manufacturer is IBM, the switch can be located in /proc/acpi/ibm/ Depending on your hardware, you can find your bluetooth switch in /proc/acpi/ Copy this file to /usr/bin and make it executable chmod +x /usr/bin/blu

blu
#!/bin/bash
cat /proc/acpi/ibm/bluetooth | awk '{ print $2 }' | while read line;
 do
   if [ $line == "enabled" ]; then
       echo disable > /proc/acpi/ibm/bluetooth
   else
       echo enable > /proc/acpi/ibm/bluetooth
   fi
   break
 done

Get a PIN Helper

For any bluetooth connection, you will need to have a pin helper agent to complete a pairing. Old distribution of bluez includes a utility passkey_agent. However the new one does not include one. So we will need to use either

bluez-gnome

http://www.kernel.org/pub/linux/bluetooth/bluez-gnome-1.8.tar.gz

or kdebluetooth

http://sourceforge.net/projects/kde-bluetooth/files/kdebluetooth4/

I'm using KDE so I chose kdebluetooth. To run it, in konsole, type

kdebluetooth4 &

Make sure the Agent is registered with dbus. A bluetooth tray icon will appear at the taskbar.

Connecting a modem via bluetooth

First, you need to bring up the internal bluetooth device by typing

hciconfig

Your output should be like this. The hci0 should be up

If not, you need to bring it up. Check your blu switched too in case it is turned off.

hciconfig hci0 up

Scan for bluetooth devices, type

hcitool scan

A list of your bluetooth devices will show up. Take note of your MAC Address of your modem device / phone.

Next, search for DUN (Dialup Networking) capabilities of the device.

sdptool search DUN

The output should be something like this.

Take note of the channel, which in this case is 1. Next step is to bind the phone modem to rfcomm via bluetooth.

rfcomm bind 0 11:22:33:44:55:66 1

Note the syntax is, rfcomm bind <dev> <bdaddr> [channel] . The dev is 0 for /dev/rfcomm0, bdaddr is your phone's MAC and channel is 1, the DUN channel from the sdptool command.

Your bluetooth modem is now binded to /dev/rfcomm0. You can use your favorite dialer such as kppp or wvdial to connect to your network carrier.

Thanks. I hope this helps.
