ok thanks.

static void advertising_init(void)
{
    uint32_t      err_code;
    ble_advdata_t advdata;
    ble_advdata_t scanrsp;
	  ble_advdata_service_data_t service_data;
    uint8_t data1[3] ={0x01,0x03,0x04};
    // Build advertising data struct to pass into @ref ble_advertising_init.
    memset(&advdata, 0, sizeof(advdata));
    advdata.name_type          = BLE_ADVDATA_SHORT_NAME;
	  advdata.short_name_len = 1;
    advdata.include_appearance = false;

    advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;
		service_data.service_uuid =0x0018;
    service_data.data.p_data = data1;
		service_data.data.size = sizeof(data1);
    
    ble_adv_modes_config_t options = {0};
    options.ble_adv_fast_enabled  = BLE_ADV_FAST_ENABLED;
    options.ble_adv_fast_interval = APP_ADV_INTERVAL;
    options.ble_adv_fast_timeout  = APP_ADV_TIMEOUT_IN_SECONDS;

    err_code = ble_advertising_init(&advdata,NULL, &options, on_adv_evt, NULL);
    APP_ERROR_CHECK(err_code);
}

after writing this function, i am not getting service data in advertisement packet. can you help me?? what is my problem??

waiting for your response

All you need to do to change the order of the advertised data is to change the order that the data is being encoded in adv_data_encode(..)

[FormerMember]

If the problem with the encoding order is solved. This thread should be marked as "solved", and the new question should be placed in a new question, due to readability for others with the same questions.

From what I can see, service data is not in the advertising data because service_data is not added to advdata. If that is not the reason, please create a new question instead of continuing in this thread.
