&lt;p&gt;The assert 2, 62 is that Radio interrupt happened when mpsl didnt expect it, likely because ESB didn&amp;#39;t disable interrupts and shut down NRF_RADIO (TASKS_DISABLE) compleltly before ending its timeslot, or that ESB accessed NRF_RADIO after it had ended its timeslot. Do you have any indication that this is occurring in your firmware?&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;br /&gt;Andreas&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
