PAIRING CONNECTION METHOD FOR DEVICES

Abstract

A pairing connection method for devices utilizes frequency to transmit information from a source device to a target device. Firstly, the frequency range of a transmitted acoustic signal is defined. The source device then divides the acoustic signal into a plurality of spectrum sections based on the length of the information, and the information per unit length is placed in the corresponding spectrum section, and a speaker is used to send out the transmitted acoustic signal. After the target device receives the transmitted acoustic signal, the target device retrieves the information from transmission frequency of the spectrum sections and establishes a connection with the source device.
