I have a question about how to connect to the manual scan.

Question

I'm a user using nrf52832 s132.
I am adjusting the BLE connection range.
scan_init is init_scan.connect_if_match = false and adv report tried to connect the device to if(p_adv_report->rssi > SET_RSSI).

But here's the question.
SCAN_NAME_FILTER already specified in scan_init in nrf_scan_filter_set, but NAMEFILTER in init_scan.connect_if_match = false seems meaningless.

When I add ble_advdata_name_find() in on_adv_report, it connects to the advertiser.

Is nrf_ble_scan_filter_set and nrf_ble_scan_filter_enable valid only if init_scan.connect_if_match = true?

It's my code:

static void scan_init(void)
{
    ret_code_t          err_code;
    nrf_ble_scan_init_t init_scan;

    memset(&init_scan, 0, sizeof(init_scan));

    init_scan.connect_if_match = false; // auto connect : true
    init_scan.conn_cfg_tag     = APP_BLE_CONN_CFG_TAG;

    err_code = nrf_ble_scan_init(&m_scan, &init_scan, scan_evt_handler);
    APP_ERROR_CHECK(err_code);

    for(int i = 0 ; i < NRF_BLE_SCAN_NAME_CNT; i++)
    {
        err_code = nrf_ble_scan_filter_set(&m_scan, SCAN_NAME_FILTER, m_target_periph_name[i]);
        APP_ERROR_CHECK(err_code);
    }

    err_code = nrf_ble_scan_filters_enable(&m_scan, NRF_BLE_SCAN_NAME_FILTER,  false);
