摘要： Disclosed is a method for variably changing a communication speed by a first device when a high-speed communication request within a range supported by the first device is input from a second device during low-speed communication of the first device with a third device in the UART communication and performing data communication with the second device at the varied high speed. A method for switching, by a device, a communication speed in an universal asynchronous receiver-transmitter (UART)-based data communication includes: measuring, by an interrupt detection module of the device, a pulse width of a start bit using an interrupt signal; calculating, by a communication speed calculation module of the device, a communication speed using a time duration for which the measured pulse width is maintained; and switching, by a communication speed switching module of the device, a current communication speed of the device to the calculated communication speed.
