Well, that wouldn't matter, as I'm going to put all that into a wrapper
class anyway.

Maybe a word about what I'm trying to do - as you may have guessed
already, it's about proximity sensing. I've put a minimal Dbus interface
into my wrapper class and it's actually working quite nicely. However,
some of the devices which I'm working with - e.g., Motorola mobile
phones - have a hardcoded discoverable timeout of 3 minutes.

This makes things a bit more difficult for me, as these phones suddenly
vanish from the list which the Dbus interface is providing, even if they
are still in range. With the hci_* interface, I can simply try to open
an ACL connection and get the RSSI value to see if they are just
invisible. How do I do this with Dbus?

Thanks for your help,
Yours, Florian
