Today, In my NRF52 unit i already use NUS with NRFUART application &amp; NRFCONNECT application to send commands and receive some data.

The standard application simply allows you to configure various shorter commands, and send them by pressing different buttons.&nbsp;</p> <p>The <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/subsys/mgmt/mcumgr/smp_svr/README.html">SMP sample</a>, with accompanying mobile apps, will allow you to send small files from a phone to an nRF device. This example doesn&#39;t use NUS though, and might be a bit overkill for what you are trying to do.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
