| − | === 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 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>
