This will ensure that only devices supporting LE Secure Connections can connect to your device.</p> <p>Check out the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/ble_sdk_app_multirole_lesc.html?cp=4_0_1_4_2_1_1">BLE LE Secure Connections multirole</a> example in the SDK.</p><div style="clear:both;"></div>
