https://devzone.nordicsemi.com/f/nordic-q-a/8842/detect-if-advertisingI&#39;m making a peripheral device that should be powered off most of the time, but never idle if on, so I want to make sure that it is always (1) connected, or (2) advertising. Checking the former is easy--just check &quot;m_conn_handle&quot; which is set by the connectionen-USTelligent Community 13Fri, 21 Aug 2015 00:43:46 GMThttps://devzone.nordicsemi.com/thread/32511?ContentTypeID=1Fri, 21 Aug 2015 00:43:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e688d123-5312-4403-8074-9e6b24527a13RK<p>I don&#39;t really see the problem. It&#39;s your code which restarts advertising, if that call doesn&#39;t fail, you&#39;re advertising, if you give the advertising no timeout then it will advertise forever, else you&#39;ll get a timeout event and then you know your advertising timed out.</p><div style="clear:both;"></div>
