&lt;p&gt;I apologize for missing this earlier. I was checking the sample, and it looks like the nRF52833 DK is not supported by the system off demo sample. Please refer to the&lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/nfc/system_off/README.html#requirements:~:text=The%20sample%20supports%20the%20following%20development%20kits%3A"&gt; supported board section&lt;/a&gt; for more details.&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;

&lt;p&gt;I will test it here but want to confirm that you have followed the steps mentioned in &lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/nfc/system_off/README.html#testing"&gt;the Testing section&lt;/a&gt;. I need to ensure that your board has entered the system_off mode.&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;

&lt;p&gt;Could you tell me which SDK version you are using? Have you made any changes to the System Off sample from the SDK? If so, could you provide details on the updates you made? I assume you are working with the&lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/nfc/system_off/README.html"&gt; NFC: System Off sampl&lt;/a&gt;e. If not, could you specify which sample you are using?&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
