Open deactivate Bluetooth when a specific connection is disconnected

Hello,

i am new with tasker and want to create a new profile which does:

- check bluetooth if a connection with a specific bluetooth connection is active/connected
- if this specific connection will be stopped/disconnected (if i stop it or if i am out of range), tasker should deactivate Bluetooth on the smartphone

Because i am a absolute beginner in Tasker, it would be great if you can explain me all steps what i have to do. I just know i need an profile which starts an task when bt connection stopps, but i dont know what exact parameters will be right.

Greets,
Viper
