Change Baud rate to 115200

[Nahom]

when i change the baud rate to 115200 my uart (Rx and TX) are giving me garbage out put.

so what do i need to change in my code(ble_app_uart example) when i have plan to change the baud rate. Do i only need to change the baud rate number ?

static void uart_init(void)
{
    uint32_t                     err_code;
    app_uart_comm_params_t const comm_params =
    {
        .rx_pin_no    = RX_PIN_NUMBER,
        .tx_pin_no    = TX_PIN_NUMBER,
        .rts_pin_no   = RTS_PIN_NUMBER,
        .cts_pin_no   = CTS_PIN_NUMBER,
        .flow_control = APP_UART_FLOW_CONTROL_DISABLED,
        .use_parity   = false,
#if defined (UART_PRESENT)
        .baud_rate    = NRF_UART_BAUDRATE_115200
#else
        .baud_rate    = NRF_UARTE_BAUDRATE_115200
#endif
    };

    APP_UART_FIFO_INIT(&comm_params,
                       UART_RX_BUF_SIZE,
                       UART_TX_BUF_SIZE,
                       uart_event_handle,
                       APP_IRQ_PRIORITY_LOWEST,
                       err_code);
    APP_ERROR_CHECK(err_code);

}

Hi, 

Not sure I understand the question correctly or not. 

Are you using the nRF5 SDK v15.3.0: UART/Serial Port Emulation over BLE example? What did you modify?

The default baud rate is 115200.
