 I&amp;#39;m using SDK 15.2. I flashed the dtm firmware on the BLE chip. How can I test its working before sending it to the certifier? I have nrfgo studio &amp;amp; I&amp;#39;m able to start &amp;amp; stop the test. I didnt understand what to do after that.

&lt;p&gt;&lt;span&gt;You can use the nRFgo Studio to set up the TX with DTM.&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;If your doing FCC or similar certification I would recommend using the Radio test example.&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/group__ble__dtm.html"&gt;&lt;br /&gt;&lt;br /&gt;&lt;/a&gt;&lt;/p&gt;

How do I send the unmodulated carrier?

&lt;p&gt;You can see this whitepaper:&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/pdf/nwp_006.pdf?cp=12_21"&gt;https://infocenter.nordicsemi.com/pdf/nwp_006.pdf?cp=12_21&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Or if you want to do production testing, here is our application note on how to that with DTM:&amp;nbsp;&lt;a href="https://infocenter.nordicsemi.com/topic/struct_appnotes/struct/appnotes_nan34.html?cp=11_3"&gt;https://infocenter.nordicsemi.com/topic/struct_appnotes/struct/appnotes_nan34.html?cp=11_3&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;If you want to test if it´s working, you can send a TX unmodulated carrier, and see if you see that on the spectrum analyzer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Best regards,&lt;br /&gt;Kaja&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
