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?
