500ms, the working mode is switched.
Input
The UART_BAUD_RESET pin is used to reset the baud rate of the device.
It defaults to a high level when powered on. In any mode, if the pin is
pulled down for more than 1000ms, the serial port parameters of the
module will restore the default 115200
Output
The ACK pin is used to indicate the status of the last user data
transmission. The pin is pulled low before the transmission is started, and
the pin is pulled high after the transmission is successful.
