2 flows, one turns on Bluetooth when receiving a call and another monitors the Bluetooth connection and will disable Bluetooth if no device is connected for 10 minutes.
I made this so my Bluetooth could turn on and auto connect to my car stereo on a phone call and auto turn off afterwards or anytime I'm not using Bluetooth. Hope someone else gets some use out of it :)
V2: adds a fork which changes the volume
