https://devzone.nordicsemi.com/f/nordic-q-a/85025/console-input-output-from-to-both-uart-and-cdc-acmHi, I&#39;m using nRF connect SDK 1.7.1 with ZephirOS. I&#39;d like to configure input / output to be redirected to UART and mirrored to USB CDC/ACM. The reason is that I&#39;m using UART to communicate with another HW component, and would like to see theen-USTelligent Community 13Wed, 23 Feb 2022 16:13:42 GMThttps://devzone.nordicsemi.com/thread/354669?ContentTypeID=1Wed, 23 Feb 2022 16:13:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a66614d8-3e76-4436-95ee-5c7c5d5c9755J&#248;rgen Holmefjord<p>Hi,</p> <p>You may reference the&nbsp;<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.0/nrf/applications/connectivity_bridge/README.html">Connectivity bridge</a>&nbsp;application, which forwards data between UART and USB CDC ACM.</p> <p>Alternatively, you can use RTT (<a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.9.0/nrf/gs_testing.html#testing-rtt"><span>How to use RTT</span></a>) or the <a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/uarte.html#topic">second <span>UART instance (UARTE1)</span></a> of the nRF52833 for logging while interfacing the other HW component on the first UART instance (UARTE0).</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
