https://devzone.nordicsemi.com/f/nordic-q-a/72393/ot-daemon-kills-itself-while-the-commissioning-processHello OT Team, I am working on the custom product where Openthread would be used. I am facing the issue while commissioning the other device to join the network. The environment setup: - A custom product that has CC2538 connected on UART and RCPen-USTelligent Community 13Wed, 10 Mar 2021 05:16:47 GMThttps://devzone.nordicsemi.com/thread/298880?ContentTypeID=1Wed, 10 Mar 2021 05:16:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:92b35dce-b385-45f5-a71c-087419e169faHardik Prajapati<p>Hi Edvin,</p> <p>It seems that it is more related to the Openthread and binary created for CC2538 from the Openthread source itself. I better ask to Openthread platform.</p> <p>Regards,</p> <p>Hardik</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/298106?ContentTypeID=1Fri, 05 Mar 2021 13:37:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d67c655e-b77f-4a19-b351-2d4302e58b45Edvin<p>Having no knowledge about the&nbsp;<span>CC2538 or their ot-daemon, it looks like you are struggling with opening the COM port. I think you need to contact Texas Instruments for this issue, as it doesn&#39;t seem to be related to the Nordic Semiconductor chip?
