https://devzone.nordicsemi.com/f/nordic-q-a/50069/serial-terminal-over-gpio-pinsHi, I am running my nRF9160 DK in &quot;nRF Only Mode&quot; (Via SW1). I would like to drive the serial terminal out via one of the GPIO pins, connected to my MAC using an FTDI serial to usb cable. https://www.digikey.co.uk/product-detail/en/adafruit-industriesen-USTelligent Community 13Mon, 22 Jul 2019 16:39:53 GMThttps://devzone.nordicsemi.com/thread/199870?ContentTypeID=1Mon, 22 Jul 2019 16:39:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:91ac6449-3486-49e9-8678-02dcd5c1ad7fRodWatt<p>I managed to get this working.</p> <p></p> <p>I added the following code to the overlay file in nrf/samples/nrf9160/spm</p> <p></p> <p><pre class="ui-code" data-mode="text">&amp;uart0 { current-speed = &lt;115200&gt;; status = &quot;ok&quot;; tx-pin = &lt;25&gt;; rx-pin = &lt;24&gt;; // rts-pin = &lt;12&gt;; // cts-pin = &lt;13&gt;; }; </pre></p><div style="clear:both;"></div>
