RSSI detection with Bluesmirf

There is no function in the smirf that can be called to find the signal strength. But this can be done with some C++ codings and calling some bluetooth protocols. This is the extent of my knowledge of RSSI. Is there some other way of doing this? Anyone know of any reference page for this? Anyone did this before? If I had a linux, I doubt that this would be a problem, but microsoft is a bit more complicated.

Also, how reliable is the signal strength report? Are there any applications out there that can detect signal strength?

Thanks for the help!
