https://devzone.nordicsemi.com/f/nordic-q-a/36607/no-callbacks-from-softdevice-to-sys_evt_dispatchMy app (S130 SDK12.3; BLE with multiprotocol support where the radio session is opened before advertising) registers function sys_evt_dispatch() as per but sys_evt_dispatch() is never called. What can be the root cause?en-USTelligent Community 13Tue, 24 Jul 2018 06:14:20 GMThttps://devzone.nordicsemi.com/thread/141076?ContentTypeID=1Tue, 24 Jul 2018 06:14:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6f381579-2613-4ef0-81da-42ca4a70f4a6Darrew<p>The timeslot is started according to your tutorial. I would have expected to see an fs event going to fs_sys_event_handler&nbsp;(fstorage.c) since advertising is blocked (and&nbsp;pending)&nbsp;by&nbsp;flash_access_in_progress() (ble_advertising.c:ble_advertising_start())&nbsp;being true for any reason I do not know.&nbsp;But, no events are coming since the&nbsp;SoC is reset after getting out from sd_app_evt_wait() for any&nbsp;reason.</p> <p>Please check <a href="https://devzone.nordicsemi.com/f/nordic-q-a/36730/flash_access_in_progress-preventing-ble-advertising-start">https://devzone.nordicsemi.com/f/nordic-q-a/36730/flash_access_in_progress-preventing-ble-advertising-start</a>, this is a flollow-up of the same problem (I will update and close this thread).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/141046?ContentTypeID=1Mon, 23 Jul 2018 21:09:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:75c6b4b8-1bb1-4a00-8fba-e5ff283f2c96Hung Bui<p>Hi Jose,&nbsp;</p> <p>&nbsp;</p> <p>I don&#39;t see a problem in your code. Which events did you expect ? Have you started the timeslot ?&nbsp;</p> <p>Could you try to follow our tutorial <a href="https://devzone.nordicsemi.com/tutorials/b/software-development-kit/posts/setting-up-the-timeslot-api">here </a>and let us know if you don&#39;t see the event ?</p><div style="clear:both;"></div>
