Dummydummy: removed parsing commandline return value - it is sufficient to check $? (checked in Gentoo)

=== ThinkPad Bluetooth with Enhanced Data Rate (BDC-2) ===
This is a USB Bluetooth Adapter that is installed in a [[CDC slot]] in the screen assembly.
=== Features ===
* Chipset: Broadcom
* Model: BCM2045B
* USB VID/PID: 0A5C:2110

=== IBM Partnumbers ===
IBM FRU PN: 39T0497

=== Linux Driver ===

The Bluetooth adapter uses the '''hci_usb''' driver {{kernelconf|CONFIG_BT_HCIUSB||||||}}.

One can enable Bluetooth by pressing {{key|Fn}}{{key|F5}}. If this doesn't work, you can load the [[ibm-acpi|ibm_acpi]] or [[ibm-acpi|thinkpad_acpi]] kernel module and run the following command with root privileges:

{{cmdroot|echo "enable" > /proc/acpi/ibm/bluetooth}}

When Bluetooth is enabled, the Bluetooth-logo LED will light up and executing {{cmdroot|lsusb}} will show an entry mentioning "Broadcom".

On recent ThinkPads the Wireless killswitch disables both WiFi and Bluetooth (verified on a ThinkPad Z60m, Z61t, T60, T61 and X61).

=== Set Fn + F5 as hotkey to enable/disable Bluetooth ===
If the {{key|Fn}}{{key|F5}} combo doesn't work for you out-of-box, you can easily use Linux ACPI subsystem to enable and disable Bluetooh. You only need to create two small files (shown below). Note that you need to have <code>acpid</code> and <code>thinkpad_acpi</code> installed and properly working. The following scripts were tested on openSUSE 10.3.
==== ACPI action script ====
<pre># cat /etc/acpi/actions/bluetooth
#!/bin/bash
# Bluetooth enable/disable script

/etc/init.d/bluetooth status

if [ "$?" -ne 0 ]; then
/etc/init.d/bluetooth start > /dev/null
echo enabled > /proc/acpi/ibm/bluetooth
echo "Bluetooth enabled"
else
/etc/init.d/bluetooth stop > /dev/null
echo disabled > /proc/acpi/ibm/bluetooth
echo "Bluetooth disabled"
fi</pre>
This script, when executed, detects the current state of Bluetooth subsystem and changes it to the opposite state.

==== ACPI event handler ====
<pre># cat /etc/acpi/events/bluetooth
event=ibm/hotkey HKEY 00000080 00001005
action=/etc/acpi/actions/bluetooth</pre>
<code>acpid</code>, once detects Fn + F5 keypress, runs the given script which disables or enables Bluetooth (and changes state of indication LED).
