https://devzone.nordicsemi.com/f/nordic-q-a/70198/is-there-ui-based-software-utility-available-to-lock-the-programHi, Greetings of the day! I used nRF Connect for desktop to program the nRF52840 device. But I can&#39;t lock the program and protect the device using this utility. I installed nRF go studio software but it does not recognize nRF52840 DK.

In the meantime you could use the nrfjprog command:</p> <p><pre class="ui-code" data-mode="c_cpp">nrfjprog --rbp</pre></p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
