https://devzone.nordicsemi.com/f/nordic-q-a/32658/logging-over-uartHi I am working with the twi_scanner_pca10056 example found in the SDK. Using a oscilloscope I can detect the logging messages on pin P0.01, even though sdt_config.h defines #ifndef UART_CONFIG_LOG_ENABLED #define UART_CONFIG_LOG_ENABLED 0 #endifen-USTelligent Community 13Wed, 04 Apr 2018 14:19:52 GMThttps://devzone.nordicsemi.com/thread/126886?ContentTypeID=1Wed, 04 Apr 2018 14:19:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0d66d8b-145a-4aef-bdd5-fa3bcd5dd562Sigurd<p>Try to set <strong>NRF_LOG_BACKEND_UART_ENABLED</strong> to 0, in order to turn off logging over UART.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/126882?ContentTypeID=1Wed, 04 Apr 2018 14:07:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d54f88b1-6811-4ca0-b064-f653ebd9a118Martin Lesund<p>Check out <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52%2Fdita%2Fnrf52%2Fdevelopment%2Fnrf52840_pdk%2Fvir_com_port.html&amp;anchor=vir_com_port" target="_blank" rel="noopener noreferrer">this</a>.</p> <p>Also could you try to <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/" target="_blank" rel="noopener noreferrer">debug </a>and also check that the signals are correct according to what you have programmed.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125932?ContentTypeID=1Mon, 26 Mar 2018 11:02:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8815a7bd-6e89-465c-adb9-e5bc681093dcfelixgattiker@xrite.com<p>Sorry, the P0.01 was I typing error. I meant pin P0.06, where I could correctly decode the logging messages with an oscilloscope. As I have written in my initial post, I expected logging messages to only appear on the above mentioned pin if&nbsp;<span>UART_CONFIG_LOG_ENABLED&nbsp;is set to 1.&nbsp;</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125689?ContentTypeID=1Fri, 23 Mar 2018 09:53:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b0624608-d01a-4b18-86a9-399dfe761842Martin Lesund<p>Hello Felix,</p> <p>It is not strange that you can see activity on pin&nbsp;<strong>P0.01</strong> since that pin is for the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52%2Fdita%2Fnrf52%2Fdevelopment%2Fnrf52840_pdk%2Fhw_32khz_crystal.html&amp;cp=2_0_3_7_7" target="_blank" rel="noopener noreferrer">32.768kHz crystal.</a></p> <ul> <li><a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52%2Fdita%2Fnrf52%2Fdevelopment%2Fnrf52840_pdk%2Fconnector_if.html&amp;cp=2_0_3_7_5" target="_blank" rel="noopener noreferrer">Connector interface</a></li> </ul> <p>Please take a look in the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v14.2.0%2Fnrf_log.html&amp;cp=4_0_0_3_25" target="_blank" rel="noopener noreferrer">Logger module</a> documentation on how to correctly initialize logging.</p> <p>Similar <a href="https://devzone.nordicsemi.com/f/nordic-q-a/21189/how-to-enable-uart-or-rtt-logging-in-examples" target="_blank" rel="noopener noreferrer">thread</a>.</p><div style="clear:both;"></div>
