Which Thread &amp; Zigbee SDK&nbsp; version are you using?&nbsp;How have you ported the application to run on the dongle? Do you have any means of debugging on the dongle? If not, I suggest you either develop on a nRF52840 DK first, so that only small modifications are needed to migrate to the dongle. If you do, it would be interesting to dig deeper and see at which state the system is in when you write it freezes (which you could check using a debugger).</p><div style="clear:both;"></div>
