what are you asking? What's "bame" for a start, and what has your question got to do with the parameters in the structure. Please ask a proper question.

The data supplied to sd_ble_gap_adv_data_set(..) is the raw data to be placed in the advertising packet. In the SDK, the advertising module, using ble_advdata_set(..) --> adv_data_encode(..), encodes the advertising data from the type ble_advdata_t to raw advertising data. Changing the order of the encoding in adv_data_encode, will change the order of the advertised data.

My answer below should answer the question.

i can't understand how to use adv_data_encode(....)

like in this function

static void advertising_init(void)
{
    uint32_t      err_code;
    ble_advdata_t advdata;

    // Build and set advertising data
    memset(&advdata, 0, sizeof(advdata));

    advdata.name_type               = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance      = true;
    advdata.flags                   = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
   advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    advdata.uuids_complete.p_uuids  = m_adv_uuids;

    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);
}

how to use adv_data_encode(..)??

just look at the code. ble_advertising_init() calls ble_advdata_set() which calls adv_data_encode(). Change adv_data_encode() or write your own version of the whole thing.

I have no idea by the way why you care about the ordering of the fields in the advertising data, it doesn't matter at all.
