merge mesh light switch server with mesh dfu example

Question

hi,

i am doing a project where i have to merge nrf mesh light switch server with mesh dfu example. i am using nrf mesh sdk v1.0.0 and nrf52832 mcu.

i have merged two programs by following this link. but now i am facing problems. rtt log is like below.

 0> <t:          0>, main.c,  233, ----- BLE Mesh Light Switch Server Demo -----
 0> <t:          0>, main.c,  259, ----- Bluetooth Mesh DFU Example -----
 0> <t:          0>, serial_handler_prov.c,  212, Generating encryption keypair...
 0> <t:          0>, main.c,  283, Enabling serial interface...
 0> <t:          0>, nrf_mesh_sdk.c,   72, APP_ERROR: E:\ATOLL_WORK\zipfiles\dfu\1\examples\light_switch\server\src\main.c:292 code 4097

it says that app_error on line 292. on line 292 " ERROR_CHECK(nrf_mesh_node_config(&config_params));" is called.

and my main function looks like this.

int main(void)
{
    __LOG_INIT(LOG_SRC_APP | LOG_SRC_ACCESS, LOG_LEVEL_INFO, LOG_CALLBACK_DEFAULT);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- BLE Mesh Light Switch Server Demo -----\n");

    hal_leds_init();

    static const uint8_t static_auth_data[NRF_MESH_KEY_SIZE] = STATIC_AUTH_DATA;
    static nrf_mesh_node_config_params_t config_params =
        {.prov_caps = NRF_MESH_PROV_OOB_CAPS_DEFAULT(ACCESS_ELEMENT_COUNT)};
    config_params.p_static_data = static_auth_data;
    config_params.complete_callback = provisioning_complete;
    config_params.setup_callback = configuration_setup;
    config_params.irq_priority = NRF_MESH_IRQ_PRIORITY_LOWEST;

#if defined(S110)
    config_params.lf_clk_cfg = NRF_CLOCK_LFCLKSRC_XTAL_20_PPM;
#elif SD_BLE_API_VERSION >= 5
    config_params.lf_clk_cfg.source = NRF_CLOCK_LF_SRC_XTAL;
    config_params.lf_clk_cfg.accuracy = NRF_CLOCK_LF_ACCURACY_20_PPM;
#else
    config_params.lf_clk_cfg.source = NRF_CLOCK_LF_SRC_XTAL;
    config_params.lf_clk_cfg.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM;
#endif
    

    

    __LOG_INIT(LOG_MSK_DEFAULT | LOG_SRC_DFU | LOG_SRC_APP | LOG_SRC_SERIAL, LOG_LEVEL_INFO, log_callback_rtt);
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "----- Bluetooth Mesh DFU Example -----\n");

#if defined ( __CC_ARM )
    rom_end    = (uint32_t) rom_base + (uint32_t) rom_length;
#elif defined   ( __GNUC__ )
    rom_length = (uint32_t) rom_end - rom_base;
#endif
    /* Take the next available page address */
    bank_addr  = (uint32_t) (rom_end & FLASH_PAGE_MASK) + FLASH_PAGE_SIZE;
    __LOG(LOG_SRC_APP, LOG_LEVEL_DBG2, "rom_base   %X\n", rom_base);
    __LOG(LOG_SRC_APP, LOG_LEVEL_DBG2, "rom_end    %X\n", rom_end);
    __LOG(LOG_SRC_APP, LOG_LEVEL_DBG2, "rom_length %X\n", rom_length);
    __LOG(LOG_SRC_APP, LOG_LEVEL_DBG2, "bank_addr   %X\n", bank_addr);

//    mesh_core_setup();

#if NRF_MESH_SERIAL_ENABLE
    ERROR_CHECK(nrf_mesh_serial_init(NULL));
#endif
    m_evt_handler.evt_cb = mesh_evt_handler;
    m_evt_handler.p_next = NULL;
    nrf_mesh_evt_handler_add(&m_evt_handler);

#if NRF_MESH_SERIAL_ENABLE
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Enabling serial interface...\n");
    ERROR_CHECK(nrf_mesh_serial_enable());
#endif

//    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initialization complete!\n");




    ERROR_CHECK(nrf_mesh_node_config(&config_params));
    
    __LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "Initialization complete!\n");

    while (true)
    {
        (void)sd_app_evt_wait();
    }
}

please help me out and let me know if any configuration changes need to be done in mesh.

Hi, 
 
 Error code 4097 mean NRF_ERROR_SDM_INCORRECT_INTERRUPT_CONFIGURATION, most likely it was returned by sd_softdevice_enable(). Please make sure you are not calling this function twice in your code. 
 
 Please step into the code and check what exactly the API that throws the error.
