https://devzone.nordicsemi.com/f/nordic-q-a/54994/spi-data-transmisson-on-lte-link-monitorHello, This is more a question than a issue. I am working on a sample to transmit data from MOSI of the SPI to UDP. It is possible to see received data through SPI on LTE Link Monitor? Do it exist another tool to visualize Serial interface on nRF Connecten-USTelligent Community 13Fri, 29 Nov 2019 10:20:56 GMThttps://devzone.nordicsemi.com/thread/222749?ContentTypeID=1Fri, 29 Nov 2019 10:20:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f1dd029b-6c1e-4a71-b00d-d7248b52339a&#216;yvind<p>Hello Ana,&nbsp;</p> [quote user=""] It is possible to see received data through SPI on LTE Link Monitor?[/quote] <p>Yes, it is fully possible, but this is application-specific and not LTE Link Monitor.&nbsp;</p> [quote user=""]Do it exist another tool to visualize Serial interface on nRF Connect?[/quote] <p>Have a look at <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.1.0/nrf/examples.html#samples-and-applications">our samples</a>, e.g. the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.1.0/nrf/samples/nrf9160/mqtt_simple/README.html#nrf9160-simple-mqtt">Simple MQTT sample</a> (nrf\samples\nrf9160\mqtt_simple\src\main.c) which is using <em>printk</em> to output on e.g. LTE Link Monitor.</p><div style="clear:both;"></div>
