&lt;p&gt;Can you please share the log from your devices?&amp;nbsp;Are you able to share a sniffer log of the network traffic? If you have another DK or Dongle you can use it to capture a sniffer log by following the guide in&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/ug_sniffer_802154/UG/sniffer_802154/intro_802154.html"&gt;nRF Sniffer for 802.15.4&lt;/a&gt;. Please share the sniffer log as a pcap file.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&amp;nbsp;Can you clarify what you mean by this? Are you only using the OTA cluster? Or do you mean that the only things you copied from the OTA example were things directly related to the OTA cluster? Do you still have&amp;nbsp;functionality required by the Zigbee stack in your example, such as for example&amp;nbsp;zboss_signal_handler,&amp;nbsp;&lt;span&gt;zboss_start/&lt;/span&gt;zboss_start_no_autostart,&amp;nbsp;zboss_main/&lt;span&gt;zboss_main&lt;/span&gt;_loop_iteration, etc?&lt;/p&gt;
&lt;p&gt;I also see that some parts of your code seem to be from earlier versions of the SDK. You should not use&amp;nbsp;things from different SDK versions together. This might cause errors or unexpected behavior, and we cannot guarantee that things will work as you expect. Some examples are&amp;nbsp;&lt;span&gt;ZB_GET_OUT_BUF_DELAYED, which was replaced with&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/group__buf.html#ga284f25d25ef8a911d00dc79bea80ce42"&gt;zb_buf_get_out_delayed(zb_callback_t callback)&lt;/a&gt;&amp;nbsp;in v4.0.0, and&amp;nbsp;ZB_BUF_FROM_REF, which was deleted in v4.0.0. See&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/zigbee_r22_migration.html"&gt;Zigbee stack migration guide: v3.2.0 to v4.0.0&lt;/a&gt;&amp;nbsp;for more information regarding stack related changes between the versions.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Best regards,&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Marte&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
