problem on receiving data with ble_app_multilink_central

[dhia1994]

Hi!  I want to send data from nrf51 to another nrf51 multilink_central! I don't have any problem about sending data! It's work with a perfect way! But my problem is how to receive data with multilink_central! the connection is established between sender and the receiver ( multilink_central).

void uart_init(void)
{
   ret_code_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,
                       (app_uart_event_handler_t)uart_evt_handle,
                       APP_IRQ_PRIORITY_LOWEST,
                       err_code);
    APP_ERROR_CHECK(err_code);

}

but i have a part of my code how make this kind of error (fatal)

and this is the part that make this problem  !

Please help me because this method doesn't work

Hi, can you add the DEBUG flag to your project? Then the log will print the actual error code instead of just "fatal"

[dhia1994]

the problem is about " APP_ERROR_CHECK (err_code) " and i don't know why ?

[Stian Røed Hafskjold]

Are you using Keil, GCC, SES or IAR?

[dhia1994]

yes i use Keil

[Stian Røed Hafskjold]

Ok. Go to Project -> Options for target ... -> C/C++. In the "Define:" textbox under Preprocessor Symbols add the flag DEBUG to the list. Compile and flash. Now you should get some more debug info, instead of just "fatal"
