:cpp:func:`esp_sleep_enable_uart_wakeup` function can be used to enable this wakeup source.
After waking-up from UART, you should send some extra data through the UART port in Active mode, so that the internal wakeup indication signal can be cleared. Otherwises, the next UART wake-up would trigger with two less rising edges than the configured threshold value.
