Obtaining RSSI feedback

I've read over the iWrap manual a bit and it looks like there are two ways to obtain the RSSI feedback from the bluetooth radio; using a flag with INQUIRY or monitoring a bluetooth link using the linkid once the connection has been established.

I can't seem to obtain feedback about RSSI using INQUIRY, even after trying multiple settings with SET BT CONFIG, including the example in the iWrap manual. Has anyone been able to get this to work?
