Abstract
Devices, systems and methods are provided to improve pairing between first and second devices to mitigate risk that either device pairs with an unintended device by reducing transmit power to limit communication range between devices to be paired, using minimum and maximum received signal strength thresholds to reject unintended devices, and instructing user to move to another location when multiple devices are detected for pairing. The second device scanning time for detecting advertising signals from the first device is adjusted to detect multiple device co-existence. Pairing is controlled to occur when the second device is the only device that the first device detects.
