Is there any example about app_uart.c?

Question

I can't find it in my SDK. Pls let me know, if there is.:)

Hi, 
 hci_slip.c file located in the app_common folder instanciate and use app_uart.c lib. 
 Have a look in this file for more information. 
 Here is the initialization to have a first idea of the implementation: 
 /** @brief Function for enabling the UART module when the SLIP layer is opened.
 */
static uint32_t slip_uart_open(void)
{
 uint32_t err_code;

 app_uart_comm_params_t comm_params =
 {
 HCI_SLIP_UART_RX_PIN_NUMBER,
 HCI_SLIP_UART_TX_PIN_NUMBER,
 HCI_SLIP_UART_RTS_PIN_NUMBER,
 HCI_SLIP_UART_CTS_PIN_NUMBER,
 HCI_SLIP_UART_MODE,
 false,
 HCI_SLIP_UART_BAUDRATE
 };

 err_code = app_uart_init(&comm_params,
 NULL,
 slip_uart_eventhandler,
 APP_IRQ_PRIORITY_LOW,
 &m_uart_id);

 if (err_code == NRF_SUCCESS)
 {
 m_current_state = SLIP_READY;
 }

 return err_code;
}
