Other specific questions regarding the RTT should be asked to SEGGER. You can find more information&nbsp;on how to use the RTT in our tutorial:&nbsp;<a href="https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/debugging-with-real-time-terminal">devzone.nordicsemi.com/.../debugging-with-real-time-terminal</a></span></p> <p>Cheers&nbsp;</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
