Kind Code:
A1
Abstract:
Disclosed is a method for communication between a wireless earphone and a charging case. In the method, by means of a case opening and closing state of the charging case, configuration of a working attribute for a first I/O interface may be achieved. Specifically, when a charging case is opened, the working attribute of a first I/O interface is firstly configured as a communication interface; before communicating with a wireless earphone, a preset negotiation signal is sent to the wireless earphone, and a communication mode with the wireless earphone is entered only after receiving a negotiation confirmation signal which is replied by the wireless earphone and which corresponds to the preset negotiation signal. Hence, in the present application, an interaction confirmation mechanism is added before the charging case communicates with the wireless earphone, thus improving the communication reliability of the charging case and the wireless earphone. Also disclosed are a charging case, a TWS earphone and a system, which have the same beneficial effects as the described method for communication between a wireless earphone and a charging case.
