Why I can't receive BLE notification after I change m_config_id from 1 to 0?

[Macl]

err_code = sd_ble_gap_connect(m_adapter, &(p_ble_gap_evt->params.adv_report.peer_addr),
                                      &m_scan_param, &m_connection_param
#if NRF_SD_BLE_API >= 5
                                      ,
            m_config_id // m_config_id //BLE_CONN_CFG_TAG_DEFAULT
                                          //can't receive notice when it is set to be BLE_CONN_CFG_TAG_DEFAULT(0)
#endif
        );

Can anyone help me?

Thank you in advance!

What version of the nRF5 SDK are you using?
