I have a bluetooth headset and I need to execute a .sh file everytime I connect it to make it work. I don't want to troubleshoot this bug since I know there's already people looking into it.

But I'm interested on a way to run that .sh script every time I connect a bluetooth device. And, if it's possible, every time I connect a headset/this specific headset.

Well, I would try this:

  1. Open a shell (bash, sh, ksh) and type: set -e (enables errorhandling)
  2. Insert Your BT- device
  3. Type: echo $?

You should get a number larger than 0, which is an errorcode. Depending on which shell you use, there might be set some environment variables:

  • ERR=$?=Errorcode
  • ERL=Linenumber if trap was detected in a script.
  • $?=0 then there is no errorcode, and U dont need to read further.

Write a script, or test by hand:

trap 'ERR=$?;errorhandler' listofcodes

errorhandler is the script that decides what todo when any of the listofcodes occur.

The list could be 1 10 14 15 (17 18 ...) or just 1 number, the one you want to catch.

# script errorhandler
errorhandler(){
case $ERR in
    1)
#    here U can take action or perhaps just ignore
    return
    ;;
    *) 
#    action if errorcode was different from 1

    ;;


esac
}

You would place line 1-4 in /etc/profile or similar to make it systemwide.

In /etc there should be an rc.d or init.d containg start and stop scripts related to boot and change in runstate. There should be a scriptfile for your BT device, check it out, but don't change content unless ...

If the errorcode in line 2 is zero then you must dig deeper.

Look into udev rules. See the ArchWiki article on udev rules and this question about running a script when a USB device is plugged in.

There are also already many questions on this site regarding bluetooth and udev rules. See:
