Communication method between earphones and charging box without master-slave switching
A recently granted patent (Publication Number: US11889255B2) discloses a communication method between earphones and a charging box. The method involves the earphones receiving a data request message from the charging box, acquiring a data packet from a sending queue, and sending a reply message containing the data packet back to the charging box. Additionally, the method includes verifying the data request message and handling successful or failed verification results by either acquiring the next data packet or resending the reply message.
Furthermore, the patent describes an earphone design that includes a memory, a processor, and a communication program stored in the memory. When executed by the processor, the communication program facilitates the communication method between the earphones and the charging box. This includes steps such as acquiring data packets, sending reply messages, and handling verification results. Notably, the method also includes a feature where if the earphones receive a data request message without a data packet a certain number of times, they switch to a charging state. This innovative technology aims to enhance the communication efficiency and reliability between earphones and their charging box, providing a seamless user experience.
