I am working on Bluetooth low energy concept project. I am getting the RSSI value
between 1 and 100. As I move the tag the RSSI value increase as the peripheral moves away
Finding distance from RSSI is bit tricky and it depends on lots of factors, even test environment and antenna orientation etc.
Following paper is having some study regarding the same
