I have searched lot of but could not get result or not even know is that result correct or not.
I do have BLE which sends RSSI and TXPower. Actually I am trying to find distance with value of RSSI and and TXPower but can't get correct one. I have followed this and also this as well but don't know which one is correct. What will be the correct formula to get distance from RSSI and TXPower
