You can refer to <a href="https://devzone.nordicsemi.com/index.php/can-nordic-please-document-how-to-debug-code-on-their-processors">this post</a> on how to do this.</p> <p>Alternatively, you can use the &#39;Debug Logger&#39; module included in the SDK. Documentation on this can be found here -&gt; <a href="http://devzone.nordicsemi.com/documentation/nrf51/5.2.0/html/a00084.html">devzone.nordicsemi.com/.../a00084.html</a> .</p> <p>Cheers, Balaji</p><div style="clear:both;"></div>
