https://devzone.nordicsemi.com/f/nordic-q-a/9537/excesive-project-consumptionHello, I&#39;ll explain my project. I developed a device that take a magnetism sample (with a sensor) each hour, but the device should be available all the time, because an operator could arrives for take the magnetism measures (saved measures).

For pointers, there is a troubleshooting section in the <a href="https://devzone.nordicsemi.com/tutorials/11/nrf51-current-consumption-guide/">current consumption guide</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35243?ContentTypeID=1Fri, 02 Oct 2015 06:44:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:64a3e0a9-abce-4cab-9106-e8ae57bd5fb4S&#233;bastien Despont<p>My advice is to start by measuring the current consumption in sleep mode without advertising. If you get more than 10uA, you have a configuration / board / components /... problem</p><div style="clear:both;"></div>
