A method and system detect directionality between two objects by measuring angles of signals incident on antenna arrays on at least one side to determine angle of incidence. The methods utilize Bluetooth Low Energy communications for both the control protocol and for providing updated information for deriving directionality. Directionality information is broadcast on selected BLE advertising or data channels, or broadcast using a hopping pattern over the BLE data channels, both at a specific interval duty cycle. If a hopping pattern is selected to transmit directionality information, then anchor information is simultaneously broadcast on the BLE advertising or data channels at a different, asynchronous duty cycle. In additional embodiments, signals incident on antenna arrays located on both target and tracking sides are used to determine angle of incidence, separate antennas are combined to form new antennas and antenna models are used to anticipate known antenna structure responses.
