Start/Stop kodi using bluetooth

Hi,

Just migrating from my previous rpi2 to a fresh rpi3.
On my rpi2, I was using a MCE remote and irexec to trigger a start/stop kodi script when media key was pressed.
I can't find a way to achieve the same using bluetooth.

The best approach I found (but not tested yet) is to use cec-client to get the TV status, coupled with a cron job.
If the tv is on, I start kodi service (otherwize I stop it)

Is there a simplier way to do it?
Thanks

why do you want to stop kodi?

My RPi is running both Kodi and MPD.
So it's better to shutdown kodi when not used, to give MPD full access to the soundcard.

Or just suspend audioengine

I'd prefer to stop kodi, and avoid graphics interrupts during MPD playback. (as volumio does)
