Title:
BAUD RATE SWITCHING METHOD AND APPARATUS FOR UART COMMUNICATION, AND INITIATOR TERMINAL
Document Type and Number:
WIPO Patent Application WO/2022/161004
Kind Code:
A1
Abstract:
Disclosed are a baud rate switching method and apparatus for UART communication, and a system and an initiator terminal. The method comprises: an initiator terminal acquiring data to be sent and corresponding to a target baud rate; sending baud rate switching information to a controlled terminal, wherein the baud rate switching information comprises the target baud rate; switching the baud rate of a first UART interface to the target baud rate; and after baud rate switching completion information sent by the controlled terminal is acquired, sending, by means of the first UART interface, said data to the controlled terminal. In the present application, when an initiator terminal needs to send data to a controlled terminal using a switched baud rate for UART communication, baud rate switching information is sent to the controlled terminal, such that the initiator terminal controls the baud rate switching of a UART interface in the controlled terminal, and the flexible switching of the baud rate for the UART communication between the initiator terminal and the controlled terminal is realized, thereby reducing human involvement, and improving the efficiency and the user experience.
