https://devzone.nordicsemi.com/f/nordic-q-a/18327/what-if-sd_evt_get-returned-id-0xcafebabeHi, I&#39;m trying to implement SOFTDEVICE_EVT_IRQHandler as in HRS example, this is the handler source part: for (;;) { uint32_t err_code; if (!no_more_soc_evts) { uint32_t evt_id; // Pull event from SOC. err_code = sd_evt_get(&amp;evt_iden-USTelligent Community 13Wed, 14 Dec 2016 12:32:53 GMThttps://devzone.nordicsemi.com/thread/70758?ContentTypeID=1Wed, 14 Dec 2016 12:32:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:09d6b354-ec4a-48fc-a32c-6e9b9f769ca4Petter Myhre<p>Could you share your complete project so I can test it here?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/70757?ContentTypeID=1Tue, 13 Dec 2016 20:49:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c76bbb9f-d3f7-4677-ae65-09f81b1d3e5fDaniel Wang<p>Just add <code>err_code = softdevice_sys_evt_handler_set(sys_evt_dispatch);</code> in the ble_stack_init() function, and you will get all the system events from the softdevice in your sys_evt_dispatch-function. Take a look at how this is done in e.g. the ble_app_proximity example. You can read more about the softdevice_sys_evt_handler_set function <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/group__softdevice__handler.html?cp=4_0_2_6_8_36_17#ga200d4e1f1c70a46e6de6343f0a7d84b1">here</a>.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/70756?ContentTypeID=1Tue, 13 Dec 2016 08:31:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a48aa8d3-f425-4493-8f97-ad9b387ab76fValer_I<p>Yes, I use code from softdevice handler, but it did not work.I did not receive events after flaash write. So I do investigation . Also i&#39;ve seen a lot posts on this issue. So may be some tuttorial needed.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/70755?ContentTypeID=1Mon, 12 Dec 2016 23:15:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:902023a5-daeb-4944-809b-25146858a4c6Daniel Wang<p>What is the goal with implementing this? Isn&#39;t it already implemented in the softdevice_handler.c?</p><div style="clear:both;"></div>
