I'm working on the very same problem, and found out similar results: RSSI is not applicable for measuring distance. LQ is the best choice, which measures the bit error rate between the 2 BT devices. I measured this using Linux, but how can I implement LQ-measurement into my android application? I was browsing the net for 3 days now, and couldn't find anything so far. Is there a .jar file I colud put into my build path, or an open source code, or how can I use this Get_Link_Quality written above? My e-mail address is goczanpeter@gmail.com, if you solve this problem, have new ideas or find out something, please do not hesitate to discuss it with me via e-mail.
