ACPI Script for bluetooth

I wrote a little bluetooth script for acpi. It's run when a fn+f5 hotkey is pressed on the thinkpad:

Code:

#!/bin/bash



if grep "^status.*disabled" /proc/acpi/ibm/bluetooth

then

        echo 'enable' > /proc/acpi/ibm/bluetooth



        modprobe bluetooth

        modprobe l2cap

        modprobe hci_usb

        modprobe rfcomm



        rm /var/run/dbus/dbus.pid

        dbus-daemon --config-file=/etc/dbus-1/system.conf

        sdpd

        hcid



else

        echo 'disable' > /proc/acpi/ibm/bluetooth



        killall dbus-daemon

        killall sdpd

        killall hcid



        modprobe -r rfcomm

        modprobe -r hci_usb

        modprobe -r l2cap

        modprobe -r bluetooth



fi



exit 0

There is one problem with it. When the script is trying to do 'modprobe -r hci_usb', it says that the module is busy, but when I try to run the command manually right after the script was run, it works perfectly.

Any ideas what's going on?

That's not the entire script is it ? There is a 'fi' after that right ? and perhaps an 'exit 0' too ?

Does it work to make a script that just runs 'modprobe -r hci_usb' ? Does it give you the same error, or just the sequence there ?

Code:

        modprobe -r rfcomm

        modprobe -r hci_usb

        modprobe -r l2cap

        modprobe -r bluetooth

does the order of these make a difference ?

As for echoing things into '/proc' ... I don't think it's a good idea :), but whatever you wanna do.

Yeah, I created a test.sh with that one line and it works, but it won't work from within this script..

Yeah, I think I solved it. rfcomm and l2cap libs just don't have enough time to be removed first. I tried inserting a sleep statement before hci_usb and it worked.

Try this:

Code:

while :

do

  if modprobe -r hci_usb

  then

    break 1

  fi

done
