I've trying for a while to get Bluetooth up and running with DSL (it was relatively easy with DSL-N) and thought others might be interested in this.

My aim is to be able to make dial-up and GPRS Internet connections over Bluetooth, transfer files from/to a DSL box (and ultimately mount a file system via Bluetooth) and use one of those Bluetooth headsets with Skype on DSL.

First things first - part one of this how-to will deal with getting Bluetooth up and running and to "pair" with a Bluetooth device.

There are no Bluetooth modules included with DSL but they can be found on the Knoppix 3.4 CD under the following directories:


My machine has an internal USB Bluetooth device and I need to load the following modules to get things working:

# insmod bluez [interface with bluez-utils]
# insmod hci_usb [USB Bluetooth driver]
# insmod l2cap [not sure what this does but required anyway]
# insmod rfcomm [required for dial-up, file transfer and serial connections]
# insmod bnep [required for IP over Bluetooth – Knoppix version will not load]
# insmod sco [required for voice over Bluetooth]

If the crc32 module is loaded first, bnep will load

First you need to load dsl-dpkg.unc, gnu-utils.unc and gt2k-0705.unc and edit /etc/apt/sources.list to point to Debian stable. Then:

apt-get install bluez-utils [27 new packages and 6 updated packages..]

For some reason the bluez-pin program will not work with DSL so you will need to edit a couple of files as a work-around:

1. /etc/bluetooth/hcid.conf

change pin_helper to /opt/;

2. /etc/bluetooth/pin

change 1234 to PIN:1234 [or whatever 4-digit code you prefer]

3. Create /opt/ and make it executable

enter  #!/bin/bash
        cat /etc/bluetooth/pin

Now we are in a position to bring up the Bluetooth interface and restart the hcid daemon to make sure the modifications to the files above are loaded:

# hciconfig hci0 up
# hcid restart

Now the interface is up, we need to check that we can see the Bluetooth device we want to “pair” with (in this example a SonyEricsson P900 mobile phone) and we also need to know its Bluetooth address:

# hcitool scan
Scanning ...
       00:0A:D9:E8:4A:65       .P900

Now all that remains is to "pair" with the device - I guess "cc" means “create a connection”. After "auth" your other Bluetooth device will request a PIN, you need to give the same one as entered in /etc/bluetooth/pin - if things work correctly, the prompt will return in the terminal window:

# hcitool cc 00:0A:D9:E8:4A:65
# hcitool auth 00:0A:D9:E8:4A:65

If all goes well, change the setting on your Bluetooth device to accept future connections from your DSL machine without authentication and you’re in business.
