Mesh and NFC together

[joao]

Hello how are you?

I don't speak English very well but I have a doubt about using mesh and nfc simultaneously.

I'm using the Nordic-Thingy52-mesh-demo example - (Nordic-Thingy52-mesh-demo - https://github.com/NordicPlayground/Nordic-Thingy52-mesh-demo)  on Nordic Thingy: 52 SDK v2.1.0 with Nordic nRF5 SDK for Mesh v1.0.1

I was able to join the nfc library with the example and I want to read the mesh network id, but when initializing the nfc and mesh network gives an error:

<t: 100900>, nrf_mesh_node_config.c, 108, Softdevice assert: 4097: 148964: 1

When used separately, they work without problems.

code:

int main(void)
{
    uint32_t err_code;

    err_code = NRF_LOG_INIT(NULL);
    APP_ERROR_CHECK(err_code);

    NRF_LOG_INFO(NRF_LOG_COLOR_CODE_GREEN"===== Thingy mesh demo node started! =====\r\n");
    nrf_gpio_cfg_input(BUTTON, NRF_GPIO_PIN_PULLUP);

    if(nrf_gpio_pin_read(BUTTON) == 0){
        uint8_t erase_page_num =  1 + ACCESS_FLASH_PAGE_COUNT + DSM_FLASH_PAGE_COUNT + NET_FLASH_PAGE_COUNT;
        uint32_t vptr_end = FLASH_MANAGER_RECOVERY_PAGE;
        uint32_t vptr= FLASH_MANAGER_RECOVERY_PAGE - erase_page_num*FDS_PHY_PAGE_SIZE*sizeof(uint32_t);

        for(; vptr_end >= vptr ; vptr += FDS_PHY_PAGE_SIZE*sizeof(uint32_t))
        {
            nrf_nvmc_page_erase(vptr);
        }
        NRF_LOG_INFO("Provisioning information erased\r\n");
        NVIC_SystemReset();
    }

    __LOG_INIT(LOG_SRC_APP, LOG_LEVEL_INFO, LOG_CALLBACK_DEFAULT);
    
    // Initialize.
    APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE);
    err_code = app_timer_init();
    APP_ERROR_CHECK(err_code);

    board_init();
    thingy_init();
    sensor_init();
    mesh_stack_init();

    create_timers();

     nrf_drv_gpiote_in_config_t gpiote_in_config;
    gpiote_in_config.is_watcher  = false;
    gpiote_in_config.hi_accuracy = false;//true;
    gpiote_in_config.pull        = NRF_GPIO_PIN_NOPULL;
    gpiote_in_config.sense       = NRF_GPIOTE_POLARITY_TOGGLE;//NRF_GPIOTE_POLARITY_HITOLO;
 
    //nrf_delay_ms(1000);

    err_code = nrf_drv_gpiote_in_init(11, &gpiote_in_config, gpiote_Button_handler);

    nrf_drv_gpiote_in_event_enable(11, true);


    uint8_t data[247];
    uint8_t tam = 247;
    err_code = drv_nfc_init();
    APP_ERROR_CHECK(err_code);
     if (err_code != NRF_SUCCESS)
    {
        NRF_LOG_ERROR("nfc init failed - %d\r\n", err_code);
        return err_code;
    }
    err_code = drv_nfc_string_record_add(THINGY_NFC_APP_ANDROID_NAME_DEFAULT, THINGY_NFC_APP_ANDROID_NAME_LEN);
    APP_ERROR_CHECK(err_code);
    err_code = drv_nfc_enable();
    APP_ERROR_CHECK(err_code);
    err_code = drv_nfc_raw_data_get(data, &tam);
    APP_ERROR_CHECK(err_code);
    /* Start sensing NFC field */
    err_code = nfc_t2t_emulation_start();
    APP_ERROR_CHECK(err_code);


    for (;;)
    {
        app_sched_execute();

        
        if (!NRF_LOG_PROCESS()) 
        { 
            power_manage();
        }
    }
}

error:

<t:        328>, main.c,  446, Initializing and adding models
<t:      70297>, nrf_mesh_node_config.c,  108, Softdevice assert: 4097:148964:1

how do I initialize the two and read the ID mesh after provisioning?

Thank you in advance.

Hi,

The softdevice assert 4097 (0x1001 in hex) corresponds to the error NRF_ERROR_SDM_INCORRECT_INTERRUPT_CONFIGURATION, which typically means that an incorrect interrupt priority configuration is used.

What have you set the NFCT_CONFIG_IRQ_PRIORITY config to? Can you post the full sdk_config.h file, or preferably the full project?

Best regards,
Jørgen

Hi Jørgen, 

Here is the project I am referring to:  Mesh_and_NFC_together

Thank you in advance.
