They will need to simulate at top level to check the event and status timing to answer your question, so this will likely take 1-2 weeks before I have an answer for you.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/277451?ContentTypeID=1Wed, 28 Oct 2020 15:50:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6505eb2f-b37a-4666-b54b-d218627f9113Kenneth<p>I will need to check internally.
