Abstract
Systems and methods are provided that may be implemented to use angle of arrival (AoA) of a signal transmitted between two Bluetooth Low Energy (BLE) wireless devices to initially authenticate a connection between the two BLE devices. In one example, bonding or pairing with a first BLE device may be restricted to only those other BLE devices having an antenna currently positioned to transmit a signal to the first BLE device from an allowed direction and within a predefined permitted range of AoA relative to the first BLE device.
