I tried uninstalling the nRF Connect, restarting the laptop and installing the nRF Connect. But , it still does not work and gives the same error. Can there be an issue with the PPK hardware or the FW?&nbsp;</p> <p>Thank you</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/331941?ContentTypeID=1Thu, 30 Sep 2021 13:12:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:419a04c4-3345-45ae-8caa-d65df3105d00Kenneth<p>In cases like this I recommend to uninstall nrf connect for desktop, restart the pc, and reinstall nrf connect for desktop and the ppk app. Can you try that?&nbsp;</p> <p>Kenneth</p><div style="clear:both;"></div>
