You are very incorrect, but there's no point in going back and forth on this given how far off we are on claims.

Suffice it to say I have talked, personally, to enough bippers to understand that there are 'spotters' and 'bippers', and which one uses the cell-phone based Bluetooth scanner (which requires no 'hardware' or 'effort' to figure out the source of a BLE signal.)
