But when I get ble connected current will up to 130uA.

Look at <a href="https://devzone.nordicsemi.com/question/5186/how-to-minimize-current-consumption-for-ble-application-on-nrf51822/#reply-5187">this thread</a>, the &quot;Tuning connection parameters&quot; and &quot;Tuning Advertising parameters&quot; sections.</p> <p>Do you use iphone in both cases? Are you using the S110 7.0.0 when you get the 60uA current consumption during advertising and 130uA during connection.</p> <p>What is actually your advertising interval and connection interval in your application?</p><div style="clear:both;"></div>
