That way one could try to see if the SiP responds.</p><div style="clear:both;"></div>RE: NRF9106 Long Running operations are not stablehttps://devzone.nordicsemi.com/thread/373182?ContentTypeID=1Mon, 20 Jun 2022 09:20:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3b51908c-8c02-49a6-a5bf-ab176d8c3cf5helsing<p>Hi Sashi,</p> <p>We will try to reproduce this ourselves with the same DK version.</p> <p>Have you seen the behaviour with any other hardware than this particular DK version?</p><div style="clear:both;"></div>
