&lt;p&gt;Sorry, English is not my native language, so my expression may not be clear enough.&lt;/p&gt;
&lt;p&gt;Yes, the two links lead to the same one.&lt;/p&gt;
&lt;p&gt;The answer in the link shows different link-key between log and Ellisys panel, why the link-keys are different?&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/samelink.png" /&gt;&lt;/p&gt;
&lt;p&gt;I want to know:&lt;/p&gt;
&lt;p&gt;Can the link-key printed in log be directly used for decryption?&lt;/p&gt;
&lt;p&gt;If no, how to transform the link-key&amp;nbsp;that can be used for decryption.&lt;/p&gt;
&lt;p&gt;Thank you for your patience!&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Question about nRF5340 Audio DK link-key</title><link>https://devzone.nordicsemi.com/thread/487748?ContentTypeID=1</link><pubDate>Thu, 06 Jun 2024 13:31:19 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:00ba404c-7d06-42dc-ab2c-c53ab894fea3</guid><dc:creator>dejans</dc:creator><description>&lt;p&gt;Hi,&lt;br /&gt;&lt;br /&gt;Your links to the relevant tickets lead to the same one.

&lt;p&gt;Can you rephrase this? What kind of transformation do you refer to?&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Dejan&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
