SYSTEMS, METHODS AND TECHNIQUES FOR DEVICE PAIRING VIA A SHORT-RANGE PAIRING MECHANISM

摘要

A watch comprises a communication circuitry configured to enable short-range communication between the watch and the portable electronic device, and a processing system including a processor. The processing system is configured to establish a pairing with the portable electronic device through a short-range pairing mechanism, determine whether the pairing with the portable electronic device is broken based on information received from the portable electronic device, and in response to the determination that the pairing with the portable electronic device is broken, transmit information indicating the breakage of the pairing to the server directly or via the portable electronic device.
