For enabling the UART loggings you need to use<span style="color:rgba(0, 0, 255, 1);"> CONFIG_LOG_BACKEND_UART</span>. Take a look at this <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_logging.html#:~:text=The%20UART%20interface%20can%20be%20configured%20as%20a%20logging%20backend%20using%20the%20following%20Kconfig%20options%3A">page</a> from the nordic which will gives you more idea.</p> [quote user=""]I assume the UART log can come out from micro USB, is this right or I need some wiring [/quote] <p>Yes that&#39;s right. If you have some trouble setting up <span style="color:rgba(0, 0, 255, 1);">PuTTY</span> then keep this <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_testing.html#putty:~:text=To%20see%20the%20UART%20output%2C%20connect%20to%20the%20development%20kit%20with%20a%20terminal%20emulator%2C%20for%20example%2C%20PuTTY">page</a> as reference.</p> <p></p> <p>Kind Regards,</p> <p>Abhijith</p><div style="clear:both;"></div>
