Until you do this you will not get any events in the event handler. Do it like this:</p> <pre><code>static void sys_evt_dispatch(uint32_t sys_evt) { fs_sys_event_handler(sys_evt); ... } </code></pre><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/96215?ContentTypeID=1Fri, 18 Aug 2017 10:10:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dcac84f2-799f-48a4-976a-4b0edf07b04fPetter Myhre<p>I&#39;m sorry, but you need to provide some more information.
