I saw that the string was not pasted correctly in the terminal. For example, I pasted the same command as you used:</p> <p><code>ot dataset set active 0e080000000000010000000300001235060004001fffe002081c85db7fd565caf40708fd1976e8a13248030510d89087d386d9650a243b5ba3af4a8659030f4f70656e5468726561642d3763343801027c4804107670d4b1f803c219e7ba0edf4839bbfa0c0402a0f7f8</code></p> <p>But in the terminal, it was pasted as this instead, resulting in the invalid argument error:</p> <p><code>ot dataset set active 0e080000000000010000000300001235060004001ff01df6c0017a205d0766045af69f76566647380c017db029bef3fc407</code></p> <p>The issue seems to be that the USB CDC ACM shell backend has some limitations when dealing with long input strings and high-speed input, which causes characters to be dropped or jumbled when pasting a long string.</p> <p>One solution I found was to paste the string in multiple parts to slow down the paste speed. Can you see if that works for you? <br />I also tried increasing the USB buffer sizes, but this did not help on my side.</p> <p>Best regards,<br />Marte</p><div style="clear:both;"></div>RE: cannot join thread network setup by otbr: Error 7: InvalidArgshttps://devzone.nordicsemi.com/thread/531611?ContentTypeID=1Mon, 14 Apr 2025 02:10:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7839818d-6a58-40f5-b018-b68be48651abminminminmin<p>Yes, but the application I use is the Thread CLI sample in nRF COnnect SDK v2.9.1.</p><div style="clear:both;"></div>RE: cannot join thread network setup by otbr: Error 7: InvalidArgshttps://devzone.nordicsemi.com/thread/531524?ContentTypeID=1Fri, 11 Apr 2025 12:37:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e520e9c1-e239-468e-9729-38fc6153bec1Marte Myrvold<p>Hi,</p> <p>This could be an issue with the application. Can you test if you see the same issue with the <a href="https://docs.nordicsemi.com/bundle/ncs-2.9.1/page/nrf/samples/openthread/cli/README.html">Thread CLI</a> sample in the nRF Connect SDK?</p> <p>Please note that we recommend using the guide in our documentation to set up the OTBR: <a href="https://docs.nordicsemi.com/bundle/ncs-2.9.1/page/nrf/protocols/thread/tools.html">nRF Connect SDK - Thread Border Router</a>.</p> <p>Best regards,<br />Marte</p><div style="clear:both;"></div>
