Why false here?

The bluez/dbus layer uses a property set (dbus::PropertySet) to keep track of
all properties for the connection. There is a separate OnPropertyChanged
callback fired when some of the properties change value. The notification for
changed device is handled through that mechanism. I will clarify with a comment
in the code.

   callback.Run();
 }
