You will need to look at the call stack, open the p_error_info and find the value of err_code.

Yes, when i am including that line I am getting fatal error, how can i solve it.

I have gone through the post of debugging with keil, but I am not getting where to include that code.

I see in the code you attached, that you have commented out the error-check in uart_init(). ( Line 21 in the snippet)

Snippet:

static void uart_init(void)
{
    uint32_t                     err_code;
    const app_uart_comm_params_t 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_ENABLED,
        .use_parity   = false,
        .baud_rate    = UART_BAUDRATE_BAUDRATE_Baud115200
    };

    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);
}

Are you getting any errors here?

If you add it back, i.e. APP_ERROR_CHECK(err_code); , are you running into the error-handler then?

You should also take a look at this post about debugging with Keil.

Hi sigurd,

Thanks for the reply, Yes I am trying to send data from modified relay example to central.

I am not able call "the uart_event_handle", not even entering into that function.

Could you help me in this?

Hi,

You are trying to send data from the "modified relay example" to the central? correct?

What happens when you call ble_nus_string_send() ? Does it return NRF_SUCCESS ? if not, what does it return ?
