https://devzone.nordicsemi.com/f/nordic-q-a/112391/cannot-open-com-access-denied-during-fundamentals-courseHello, I&#39;m stuck in the nRF Connect SDK Fundamentals course on lesson 3, exercise 1. When opening the COM port to view the printk messages, I get an error when connecting to VCOM0. Connection to VCOM1 works, but there I can&#39;t see any output. en-USTelligent Community 13Fri, 23 Aug 2024 16:22:34 GMThttps://devzone.nordicsemi.com/thread/499616?ContentTypeID=1Fri, 23 Aug 2024 16:22:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:817ae31b-1302-4ea5-8e20-ada0d866b4e3JLarkin<p>Closing VS Code and then restarting it should fix this. It doesn&#39;t always properly release its claim on a COM port.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/491453?ContentTypeID=1Sun, 30 Jun 2024 12:57:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eab59c7f-ac2a-4528-a70d-29c18b0c2abewyang0824<p>When I link to the serial terminal for the first time, I can print, but when I accidentally delete the terminal and reopen it, I get this error, should I close the previous terminal?</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1719752205661v1.png" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/490169?ContentTypeID=1Mon, 24 Jun 2024 08:32:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:003b44bc-9eb7-4fc4-858f-ab752ade127cRene Fischer<p>Somehow some program blocked access to the port. Also when reconnecting the kit.<br />I think it was VSCode.</p> <p>It works now.</p><div style="clear:both;"></div>
