As in, if I buy a dongle that will plug into my USB, and I make certain that it is a Widcom, I should be able to use the signal strengths to determine location?
However, the point to note is that I have seen really different behaviors of the received RSSI data from different bluetooth dongles. One of my friend dongle is a no-name very long range BT dongle that he got for peanuts, and the RSSI data the plugin receives seems to be very accurate. I could really determine an approximate distance of the BT phone to the BT dongle. (I would love to get 3 of these dongles for testing but unfortunately there is no visible branding on the unit, and the shop doesn't sell them anymore )
In comparison, the RSSI data received from my own BT dongle or my Dell Laptop integrated bluetooth is very inaccurate, and with those I can only determine if the phone is stuck to the dongle (positive rssi received), within 1 meter (0 rssi), or within 5 meters (negative rssi, but never the same - very fluctuating), or away more than 5 or 6 meters (no connection possible anymore to the BT phone).
Hope this helps.
