&lt;p&gt;Could you open the nRF serial terminal in VSCode and try the same?&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/7288.pastedimage1771409856630v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Then select the corresponding COM port and connect the DK.&lt;/p&gt;
&lt;p&gt;After that, you should see this message on the terminal upon resetting the board:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/1321.pastedimage1771409930574v4.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Then try pressing the keyboard keys.&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;OR, Another method is, in case you need to use the serial terminal app,&lt;/p&gt;
&lt;p&gt;please change the terminal mode from Line to SHELL and you can observe the same thing:&lt;/p&gt;
