Problems solved by technology

[0003] In the prior art, the single-wire communication between the charging box and the wireless earphone is realized by the single-wire communication scheme of the integrated chip and the single-wire communication of the input / output (Input / Output, I / O) simulation. The former integrated chip will occupy the space of the circuit board, and It will increase the cost of the product, and the transmission speed of the integrated chip is not high; the latter needs to customize the communication protocol through software, which increases the complexity of software development. The problem of single-wire communication needs to be solved urgently

Abstract

The invention provides a single-line communication method and a related product, the method is applied to a charging box, a first wireless earphone is placed in the charging box, and the method comprises the following steps: when the charging box charges the first wireless earphone through two power supply contact points, if it is monitored that the charging box needs to communicate with the firstwireless earphone, switching the charging box from a charging state to a communication state; and calling a universal asynchronous receiver transmitter (UART) module integrated in a controller of thecharging box to establish a communication link between the charging box and the first wireless earphone. Single-line communication between the charging box and the wireless earphone is realized by switching the working state of the charging box, so that the charging function and the communication function of the charging box for the wireless earphone are met, the structure is kept simple and attractive, and the hardware resource occupation and the software development difficulty are reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a single-line communication method and related products. Background technique [0002] With the development of science and technology in modern society, wireless earphones have been widely used due to their convenient use, and their volume is getting smaller and smaller. In order to achieve long battery life, wireless earphones need to be equipped with a matching charging box to charge them. , At the same time, the wireless headset also needs to communicate with the charging box, so that it can perform operations such as entering the pairing state, restoring factory settings, or upgrading over the air technology (Over the Air Technology, OTA). [0003] In the prior art, the single-wire communication between the charging box and the wireless earphone is realized by the single-wire communication scheme of the integrated chip and the single-wire communication sim...
