## Debugging

If this component doesn't work out of the box for your device please update your configuration to enable the debug output of the UART component and increase the log level to the see outgoing and incoming serial traffic:

```

logger:

  level: DEBUG

uart:

  id: uart_0

  baud_rate: 9600

  tx_pin: ${tx_pin}

  rx_pin: ${rx_pin}

  debug:

    direction: BOTH

```
