&lt;p&gt;For more information on the power modes of the nRF51822, I&amp;#39;d recommend you to have a look at &lt;a href="http://devzone.nordicsemi.com/index.php/what-is-the-power-and-clock-model-of-peripheral-in-nrf51"&gt;this question&lt;/a&gt;.&lt;/p&gt;
&lt;p&gt;As you can see from the above, the core will not go to system off in between advertising events, since only GPIO and reset can wake the chip up from this mode, but will go to system on, idle sleep mode. This will normally give a current consumption of ~3 µA in between connection events / advertising events.&lt;/p&gt;
&lt;p&gt;If you have problems with IAR, I&amp;#39;d recommend you to post that as a separate question. However, to get IAR project files, you must either take a look at the zip file of the SDK, or make sure to select &amp;quot;Custom installation location&amp;quot; when installing.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
