Abstract
Devices, systems and methods are provided to improve pairing between two devices by employing an inductive antenna circuit (e.g., 13.56 MHz) in addition to another wireless communication antenna circuit (e.g., 2.4 GHz) and a pairing protocol to minimize pairing between unintended devices. Communications via inductive antenna circuit (e.g., 13.56 MHz) require that the devices to be paired to be in close proximity to each other, which increases the likelihood of intended pairing between these devices. When the inductive pulses of the first device are detected by the second device, the second device commences advertising signals with time stamps. The inductive pulses and the time stamps facilitate synchronizing scanning windows of the first device with the advertising signals of the second device to lessen the likelihood of interference of advertising pulses from an unintended device.
