Re: [9fans] bluetooth

you could just set the mtime to the time of the last successful 
operation on that device

What do you mean exactly by "sees"? ...
     

all devices that are listening on inquiry scan channels and respond to
inquiry requests.
   


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.
