&lt;p&gt;At least on the main branch, this is now the behavior. You could also add this commit, and see if works better for you:&amp;nbsp;&lt;a href="https://github.com/nrfconnect/sdk-nrf/pull/14392/commits/a8969e9e105301f3a25c5498c13d394107b9ff3c"&gt;https://github.com/nrfconnect/sdk-nrf/pull/14392/commits/a8969e9e105301f3a25c5498c13d394107b9ff3c&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;also make sure to enable the UART TX Characteristics notification in iOS nRF Connect for mobile app:&lt;/p&gt;

&lt;p&gt;That should have worked fine. What terminal are you using ? Make sure to enable new-line and/or carriage return in the terminal program.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
