If it is, then the define will be there and it will be included by the preprocessor during the build.</p> <p>However, due to the way the nRF Connect SDK and Segger Embedded Studio is integrated you cannot always trust that the inactive code opacity works as expected. If that causes confusion or is annoying I suggest you turn it off to avoid confusion (Tools -&gt; Options..., Then search for &quot;Inactive&quot; and set the Inactive Code Opacity).</p> <p>Einar</p><div style="clear:both;"></div>
