Just as a heads up Nordic does not use C++ in the nRF Connect SDK. The Zephyr kernel support applications written in C++. See Zephyr documentation for details. So my competency in C++ is not the greatest. However from a quick look I don&#39;t see much of C++ in your code. I will take a look at it and see if I can recreate your findings</p> <p>Regards</p> <p>Runar</p><div style="clear:both;"></div>
