It&#39;s the limitation of the BLE stack. The only option if you use the softdevice is to start scanning right after it&#39;s connected. And use a short connecting timeout to avoid scan being blocked for a long time if the connection can&#39;t be established.&nbsp;</p><div style="clear:both;"></div>
