Hi Gordon. I have five boards, but at moment I'm only using one - nothing fancy just attempting to get some correlation between distance and RSSI signal emitted by the puck. I saw this as the first step, without some form of calibration, reliable triangulation would be hard to achieve?
I've also read of indoor location tracking being done using magnetic fields. Could the puck's magnetometers be up to this when used in an array - maybe if the person carried a magnet?
