Thanks for such great news! My problem now that device in undiscoverable
mode, and it not respond to scan for security, but i know it mac address,
and want to simply check rssi distance...
As i read linux bluetooth have ability to send page request to known mac
address and get rssi data for it. But i cant see such info for dbus or some
code examples.
