bluetoothd already supports the RSSI information in its D-Bus API. You
will get the information as a "RSSI" property within the DeviceFound
signals. If you really don't want to use the D-Bus API you might want to
take a look how bluetoothd handles this internally. A good place to
start from is the hcid_dbus_inquiry_result function in the
src/dbus-hci.c file and the inquiry_result_with_rssi function in the
src/security.c file.
