 chip: nrf52840 
 node: MTD not SED 
 network: one OTBR as leader and one MTD as child 
 After about 4~10 hours, MTD will offline. Sometimes it can reconnect to the network but sometimes it can never reconnect until I reboot it.

&lt;p&gt;Looks like it appears in the following discussion and the second one has an explanation from the Nordic development team. You can add more questions on that issue.&lt;/p&gt;

&lt;p&gt;&lt;span&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;I&amp;#39;ve been testing for about 12 hours since last night, and I haven&amp;#39;t seen any of the previous offline. I will add more MTD and test a week.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;But I also see the same Frame rx failed error output:&lt;/span&gt;&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;1. The firmware I test now is define by our product hardware(some gpio and sensor). It will report some data every half hours by coap udp.&lt;/p&gt;
&lt;p&gt;I also test the openthread/cli project and add some code as follow. I think you can use nrf52840DK board to test.&lt;/p&gt;

&lt;p&gt;I have the following suggestions for the issue:&lt;/p&gt;
&lt;p&gt;1) Can you provide more information about your MED device? Is it modified form&amp;nbsp;&lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/nrf/samples/openthread/coap_client/README.html"&gt;Thread: CoAP Client &lt;/a&gt;? Did it do something after connecting with OTBR formed thread network? I want to repeat the same test on my side to understand the issue.&lt;/p&gt;
&lt;p&gt;2) Are you able to test with the latest NCS2.2.0? Try to also use the latest OTBR suggested(&lt;span&gt;0895ad5&lt;/span&gt;).&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
