&lt;p&gt;Ok, so this means they have an IP connection, but for some reason, the UPD command on the CLI device has some issue showing it receives the UDP message.&lt;/p&gt;
&lt;p&gt;Have you run a command like &amp;quot;udp connect fdde:ad00:beef:0:bb1:ebd6:ad10:f33 11&amp;quot; to specify&amp;nbsp;it should listen to&lt;span&gt;&amp;nbsp;sending device IP on port 11 for coming UPD package.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="https://github.com/openthread/openthread/blob/main/src/cli/README_UDP.md"&gt;openthread/README_UDP.md at main · openthread/openthread (github.com)&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;If the problem still exists, could you try to report this issue to&amp;nbsp;&lt;a href="https://github.com/openthread/openthread/issues"&gt;Issues · openthread/openthread (github.com)&lt;/a&gt;&amp;nbsp;about this potential bug on CLI UDP command?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;

&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Yes I can ping the target child successfully. and we can get the routing tables.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;did you try to use the cli&amp;nbsp;open UDP &amp;amp; Bind code?&amp;nbsp; &amp;nbsp;(bind multicast (&amp;nbsp;&lt;/span&gt;&amp;quot;::&amp;quot;&amp;nbsp;&lt;span&gt;) to port 11)&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Mohammed&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: openthread FTD child not receiving UDP message</title><link>https://devzone.nordicsemi.com/thread/381004?ContentTypeID=1</link><pubDate>Wed, 10 Aug 2022 11:52:07 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:72116c8c-e67d-4240-8ed8-5a3b46ad7322</guid><dc:creator>Charlie</dc:creator><description>&lt;p&gt;&lt;span&gt;Hi Mohammed,&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Are you able to ping the target child node?&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Have you checked the devices routing tables? &lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;Best regards,&amp;nbsp;&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;span&gt;sorry for late update, I tried use (ML-EID) to send UDP message to child node but the child did not receive&amp;nbsp;any message until changing the role to router.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I add (&amp;nbsp;&lt;/span&gt;&lt;span&gt;CONFIG_OPENTHREAD_CHILD_SUPERVISION&lt;/span&gt;&lt;span&gt;=y ) but did not work for me.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: openthread FTD child not receiving UDP message</title><link>https://devzone.nordicsemi.com/thread/377189?ContentTypeID=1</link><pubDate>Fri, 15 Jul 2022 12:16:37 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:5ef764a3-07f0-409f-b789-ec3e4f8aff3a</guid><dc:creator>Charlie</dc:creator><description>&lt;p&gt;Hi Mohanmed,&lt;/p&gt;
&lt;p&gt;Have you tested with&amp;nbsp;Mesh-Local EID (ML-EID)? I think you should use this address on your application.&lt;/p&gt;
&lt;p&gt;I think using RLOC should be also fine on your test. Can you use ping to test? you can check the routing table of devices like&amp;nbsp;&lt;a href="https://openthread.io/codelabs/openthread-hardware#9"&gt;Build a Thread network with nRF52840 boards and OpenThread&lt;/a&gt;?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
