 nrfutil is a replacement for nrfjprog. I have previously relied on pynrfjprog for automated testing and programming. This test procedure uses RTT shell to send test commands to the DUT and receive answers back, However, (py)nrfjprog</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 02 Sep 2026 12:27:07 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/129082/how-to-read-write-rtt-using-nrfutil" /><item><title>RE: How to read/write RTT using nrfutil</title><link>https://devzone.nordicsemi.com/thread/570825?ContentTypeID=1</link><pubDate>Wed, 02 Sep 2026 12:27:07 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:16866a98-9f0a-4534-a870-c2f94e788f2c</guid><dc:creator>Nissanth</dc:creator><description>&lt;p&gt;Hi&amp;nbsp;Fridtjof,&amp;nbsp;&lt;/p&gt;
&lt;p&gt;nRF Util does not currently support RTT, unfortunately. For scripted testing i would recommend &lt;a title="pylink-square" href="https://github.com/square/pylink/tree/master"&gt;pylink-square&lt;/a&gt;, which is a SEGGER&amp;#39;s python wrapper for the J-link library. It gives you rtt_start(), rtt_read() and rtt_write(), which is the closest replacement for what you had.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Regards,&lt;/p&gt;
