It&#39;s registered by&nbsp;NRF_SDH_BLE_OBSERVER() macro inside nrf_ble_scan.h</p> <p>So when you set&nbsp;connect_if_match = false you will then&nbsp;receive NRF_BLE_SCAN_EVT_FILTER_MATCH event inside&nbsp;scan_evt_handler() for each advertising packet that matched the filter. You can use the data provided in the event to find if it&#39;s the device you want to connect to. The information about the advertiser is inside&nbsp;p_scan_evt-&gt;filter_match.p_adv_report that you can parse.&nbsp;</p><div style="clear:both;"></div>
