This will not work, as the nRF5 devices only support SWD. Additionally, you might want to consider using nrfjprog instead for development, as that is more user friendly (but still a command line tool). That is part of the <a href="https://www.nordicsemi.com/eng/nordic/Products/nRF51822/nRF5x-Command-Line-Tools-Win32/33444">nRF5x-Command-Line-Tools</a>&nbsp;distribution.</p><div style="clear:both;"></div>
