In any case, I don&#39;t recommend using nRFGo Studio, as it is very old and no longer regularly updated. Instead, I&#39;d recommend that you use the <a href="https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF-Connect-for-desktop">nRFConnect for Desktop Programmer app</a>, which supports our newest devices and is updated on a regular basis. You should also make it a rule of thumb to erase the chip before writing new firmware onto it in order to avoid these kinds of errors.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
