=== ThinkPad Bluetooth with Enhanced Data Rate (BDC-2 / BDC-2.1) ===
 
This is a USB Bluetooth Adapter that is installed in a Bluetooth Daughter Card (BDC) slot in the screen assembly.

* Chipset: Broadcom
 
* Model: BCM2045B (BDC-2)
 
* USB VID/PID: 0A5C:2110 (BDC-2)

=== 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 [[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 or Fn + F6 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.
 
 
 
Newer ThinkPad T Series Models cycle through four options:
 
# WLAN on + bluetooth on
 
# WLAN off + bluetooth off
 
# WLAN off + bluetooth on
 
# WLAN on + bluetooth off
 
If you don't like this and want to control only bluetooth without affecting WLAN you can simply add {{key|Fn}}{{key|F6}} as the bluetooth toggle. To do that use the second ACPI event handler scipt below instead of the first one.
 
==== 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).
 
 
 
To use {{key|Fn}}{{key|F6}} for bluetooth toggling only and leave the function of FN+F5 on newer ThinkPads intact use the following script instead of the one above:
 
<pre># cat /etc/acpi/events/bluetooth
 
event=ibm/hotkey HKEY 00000080 00001006
 
action=/etc/acpi/actions/bluetooth</pre>
