How do I do this with Dbus? and that RSSI value is totally different from the one you get via an inquiry and thus you can't put them together. If you could, I would have done this inside the kernel. And no matter what you try, creating an ACL baseband connection is most expensive operation in Bluetooth. So it takes time and that it takes even more time if you have to wait for the page timeout if the device is not in range.
