 Posted: Sun Dec 09, 2007 6:10 pm Post subject: [ebuild] Wirelessctl - save & restore BT/WLAN state |
 |
|
I wrote a little script to save the states of the bluetooth and wlan interface at shutdown and to restore theses states at boot.
It's made for my asus laptop but I try to make it generic.
If you find mistakes or things like that...please let me know

For example here is my conf for my ASUS laptop.
| Code: |
/# RESTORE_ON_START:
# Do you want to restore your wireless settings ?
# no - Do not restore state
# yes - Restore state
RESTORE_ON_START="yes"
# SAVE_ON_STOP:
# Do you want to save changes made to your wireless settings ?
# no - Do not save state
# yes - Save state
SAVE_ON_STOP="yes"
# BLUETOOTH
# Do you have a bluetooth adapter ?
# no - no bluetooth adapter present
# yes - bluetooth adapter present
BT="yes"
# Path where we can test if bluetooth adapter is active (test if : 0 or 1)
BT_TEST_PATH="/sys/devices/platform/asus-laptop/bluetooth"
# Command(s) to start the bluetooth adapter
BT_START_CMD="echo "1" > "/sys/devices/platform/asus-laptop/bluetooth""
# Command(s) to stop the bluetooth adapter
BT_STOP_CMD="echo "0" > "/sys/devices/platform/asus-laptop/bluetooth""
# WLAN
# Do you have a wlan adapter ?
# no - no wlan adapter present
# yes - wlan adapter present
WLAN="yes"
# Path where we can test if wlan adapter is active (test if : 0 or 1)
WLAN_TEST_PATH="/sys/devices/platform/asus-laptop/wlan"
# Command(s) to start the wlan adapter
WLAN_START_CMD="echo "1" > "/sys/devices/platform/asus-laptop/wlan" && modprobe iwl3945"
# Command(s) to stop the wlan adapter
WLAN_STOP_CMD="echo "0" > "/sys/devices/platform/asus-laptop/wlan" && modprobe -r iwl3945"
