I maybe gonna change the complete interface to the inquiry stuff in the
future and so I haven't added support for inquiry with RSSI so far. You
don't need to hack something on hcidump, simply use the HCI raw socket
interface. Send the inquiry command and wait for the events. You will
find example code for this and listening on the 1.1 inquiry event in the
mailing list archive. It should be easy to adapt.
Regards
Marcel
