    Default Bluetooth Tx Power


      Hi all,


      I'm interested in getting the distance between some bluetooth devices using RSSI values. The equation I plan on using is:


      Distance = 10 ^ ((TxPower – RSSI)/(10 * N))


      I know this won't be the most accurate measurement of distance, but for my use it will be sufficient. I already have the RSSI values being polled, the only thing I cannot find is the TX Power for the Edison. I know that this value cannot be changed based on previous posts, but I cannot find anything on the default value.


      Further, I know the command 'hciconfig hci0 inqtpl' gives a value of 'Inquiry transmit power level: 0' but I do not believe this is the value I need. Any help is appreciated.
