Script to read and restore bluetooth, wlan, and wwan rfkill settings when running Linux on a ThinkPad.

Intention

I wrote it, because my ThinkPad X200s always starts into Linux with all rf devices (bluetooth, wlan, wwan, etc.) switched on. This script now gives me the possibility to dump the state of the devices at shutdown and restore them when booting up again. Thus only having, e.g. wwan switched on.

Open Topics

Eventually there will also be a small GUI for a quick overview and easy switching of the states. If possible I will even try to bind the GUI to FN+F5 then.

Prerequisites

The script is a Tcl script and needs a Tcl interpreter of at least version 8.5. To check if one is installed you may use your package manager or check manually, e.g. like so: $ which tclsh /usr/bin/tclsh $ echo 'puts [info patchlevel]' | tclsh 8.5.7

Installation

To use the main functionality (restoring of the device states after boot up) the script has to be installed:

1. become root or use sudo for the following steps
2. review and execute install.sh in the source directory
3. run the script once to save the current state locally, e.g. tprfkill.tcl save
4. edit the settings to match your desired configuration
5. run the script again to load the settings, e.g. tprfkill.tcl reset

Note: The local settings will not be read by dump and restore. Step 3-5 are only meant to setup the currently desired configuration.

Usage

tprfkill.tcl read Prints a line like "name (type) at file is state", e.g. tpacpi_bluetooth_sw (bluetooth) at rfkill1 is soft_blocked

tprfkill.tcl save Will save the current rfkill status of the devices in the local settings at "~/.tprfkillrc". This can be used as template to edit for use by "reset". Possible values are soft_blocked => device should be off unblocked => device should be on keep => do not touch this device

tprfkill.tcl reset Reset the state of all devices from the defaults, e.g. as loaded from the local settings.

tprfkill.tcl dump Dump the current status of the rfkill devices in a simple machine readable file. This should only be used by the init-script.

tprfkill.tcl restore Restore the previously dumped status of the rfkill devices. This should only be used by the init-script.

tprfkill.tcl all on|off Switch all devices on (unblocked) or off (soft_blocked).
