Android bluetooth. Determine if the paired device is set to 'on'

I want to determine if the paired device is active. I really don't need to connect to it, just determine if it has a heartbeat.

I am struggling with a series of I / O errors when trying to connect a bluetooth socket, but I'm not sure what I really need.
