Integrating nfc_callback() for ...EVENT_FIELD_ON / OFF in to wake_on_nfc example

[Pra_Engr]

Environment:

Nordic SDK 15.2.0

Eval kit nRF52840-DK / PCA10056

SES debugger on Windows 10

I was trying to integrate nfc_callback() for ...EVENT_FIELD_ON  / OFF from nfc_launchapp_record example in to wake_on_nfc example.

But ...EVENT_FIELD_ON  / OFF events are not recognized in the new wake_on_nfc -> nfc_callback().

Any quick hints / solutions Please !?

Thanks !

Hi,

Can you post your code/project showing how you integrated this? 

Best regards,

Hi Jorgen

Here is the code *added* to wake_on_nfc_pca10056 example

static void nfc_callback(void * p_context, nfc_t2t_event_t event, const uint8_t * p_data, size_t data_length)
{
    (void)p_context;

    switch (event)
    {
        case NFC_T2T_EVENT_FIELD_ON:
            nrf_delay_ms(2000UL);
            bsp_board_led_on(BSP_BOARD_LED_2);
            NRF_LOG_DEBUG("NFC_T2T_EVENT_FIELD_ON \n");
            break;

        case NFC_T2T_EVENT_FIELD_OFF:
            NRF_LOG_DEBUG("NFC_T2T_EVENT_FIELD_OFF \n");
            break;

        default:
            break;
    }
}

static void utils_setup(void)
{
    ret_code_t err_code;

...
...
...

    // Schedule a timeout event every 500 miliseconds
    err_code = app_timer_start(m_tick_timer, APP_TICK_EVENT_INTERVAL, NULL);
    APP_ERROR_CHECK(err_code);

    /* Set up NFC */
    err_code = nfc_t2t_setup(nfc_callback, NULL);
    APP_ERROR_CHECK(err_code);

    NRF_LOG_INFO("NFC Tag example started.");

}

int main(void)
{

...
...


    /* Start sensing NFC field */
    err_code = nfc_t2t_emulation_start();
    APP_ERROR_CHECK(err_code);

    while (true)
    {
...
...
...
    }
}

I am sorry if you think it is simple question, but I am new to Nordic.

Thanks
