&lt;p&gt;I&amp;nbsp;tested your code with the serial example in sdk 15.3.0, but it&amp;nbsp;seems to work here.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;main.c used for the test:&lt;/p&gt;
&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-bcf3ee97fadb420880ab1b76fd3c1996/main.c"&gt;devzone.nordicsemi.com/.../main.c&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;And the terminal output:&lt;/p&gt;
&lt;p&gt;&lt;img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-bcf3ee97fadb420880ab1b76fd3c1996/pastedimage1563281822475v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Could you try the code above with the serial example to check if you still get the same result? Also, I guess you may have considered it already, but I would suggest trying our &lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_cli.html?cp=5_1_3_10"&gt;CLI&lt;/a&gt; example if you haven&amp;#39;t done it already. The project can be found in &amp;lt;sdk root&amp;gt;/examples/peripheral/cli.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
