It looks like your requirement might be satisfied by one or
the other of these things in the /net/bt/devices record:

- a discoverable (ie "responded to most recent inquiry") flag
- a timestamp for last inquiry response received (1 second resolution?)

I'm reluctant to remove devices altogether when they don't
respond to inquiry, because it may still be possible to
connect to a non-discoverable device by paging its address.
