== Introduction ==

Bluetooth is finally emerging as a robust and widely supported local area communications technology for short-distance wireless data transfer. Bluetooth is being used for communications with cellphones, cameras, headsets and microphones, keyboards, mice, PDA's and storage devices.

== Devices ==

Most of the newer laptops come with Bluetooth support built right in. If you are using a desktop or do not have bluetooth support built in, you can use a USB Bluetooth dongle to get bluetooth support.

A list of Bluetooth devices supported under Linux is listed [http://www.holtmann.org/linux/bluetooth/features.html here]. If your device has an HCI version listed, it should work under Linux.

== Installation and Configuration ==

Open up a terminal window, and install the requisite packages and their dependencies.

{{{
sudo apt-get install bluez-utils
}}}

Then, connect your Bluetooth device if you are using one. Then restart the Bluetooth services by doing

{{{
sudo /etc/init.d/bluez-utils restart
}}}

Verify that your bluetooth device has been detected, and the appropriate modules loaded by viewing the lsusb (in case of usb device) output.

lsusb output:
{{{
Device 005: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
}}}

Also, view the output of the command '''hcitool dev''' which will give you a listing of bluetooth devices on your computer.

hcitool output:
{{{
Devices:
 hci0 00:11:95:00:1A:CF
}}}

Your bluetooth device will have a different id. If you get all zeros, then try restarting the bluez-utils service and try again.

== Setup Devices ==

=== Find Device Addresses ===

To connect to a Bluetooth device, you will need to find the address of the device. Make the device discoverable (look for a "Connect" button on many keyboards and mice or look in the device's manual) and then search for the device with this command:

{{{
sudo hidd --search
}}}

Each device should have its own address in a aa:bb:cc:dd:ee:ff format.

=== Connect Devices for Current Session Only ===

To temporarily connect to a device, use this command where 'aa:bb:cc:dd:ee:ff' is the address of the device you want to connect to:

{{{
sudo hidd --connect aa:bb:cc:dd:ee:ff
}}}

Your device should now be connected for the current session.

=== Connect Devices at Startup ===

To connect the device at startup every time, use the following commands to edit the configuration file:

{{{
sudo cp /etc/default/bluez-utils /etc/default/bluez-utils_backup
sudo nano /etc/default/bluez-utils
}}}

Look for the following line:

{{{
HIDD_ENABLED=0
}}}

Change it to:

{{{
HIDD_ENABLED=1
}}}

Next, look in the same file for a line similar to:

{{{
HIDD_OPTIONS="--connect AA:BB:CC:DD:EE:FF --server"
}}}

Add additional "connect" arguments for each device that you want connected at startup so that it looks like this:

{{{
HIDD_OPTIONS="--connect AA:BB:CC:DD:EE:FF --connect AA:BB:CC:DD:EE:FF --connect AA:BB:CC:DD:EE:FF --server"
}}}

Save the file.

Finally, add HIDP to /etc/modules:

{{{
echo hidp | sudo tee -a /etc/modules
}}}

Your Bluetooth devices should now be connected at startup.
