this is a general Bluetooth problem. If you don't have a connection
between two devices then there is no radio traffic. This is one of big
difference between Bluetooth and WiFi.

The only possible solution is to have the other device always be in
discoverable mode and use periodic inquiry with the RSSI values or
defines something for extended inquiry to transmit additional
information.

Regards

Marcel
