 I am curious how to test nRF54L15 BLE sensitivity and Blocking. 
 I am currently using: 
 1) nRF Connect For Desktop&amp;quot; v5.1.0 
 2) Direct Test Mode v2.4.0 
 
 TX test work finde but I can&amp;#39;t figure out, how to setup receiver test. in Direct</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Wed, 02 Apr 2025 14:51:15 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/118742/ble-measurements-nrf54l15" /><item><title>RE: BLE measurements nRF54L15</title><link>https://devzone.nordicsemi.com/thread/530297?ContentTypeID=1</link><pubDate>Wed, 02 Apr 2025 14:51:15 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:d98f274f-5747-4c92-80e6-d33f78e70d90</guid><dc:creator>J&amp;#248;rgen Holmefjord</dc:creator><description>[quote user="Hans Erik Gram"]So if I set it in DTM mode, I can do my receiver&amp;nbsp;test ?[/quote]
&lt;p&gt;Yes, but you need to program the nRF54L15 board with the &lt;a href="https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/samples/bluetooth/direct_test_mode/README.html"&gt;DTM firmware&lt;/a&gt; firsts.&lt;/p&gt;
[quote user="Hans Erik Gram"]Do you know which IO pin on the nRF54L15-PDK bord which is UART?[/quote]
&lt;p&gt;The nRF54L15 (P)DK has two virtual COM ports, available on the pins described in the &lt;a href="https://docs.nordicsemi.com/bundle/ug_nrf54l15_dk/page/UG/nRF54L15_DK/program_debug/virtual_serial_ports.html"&gt;DK user guide&lt;/a&gt;. By default, DTM uses Serial 1 available on P1.04 (TX) and P1.05 (RX).&lt;/p&gt;
[quote user="Hans Erik Gram"]As weel what is the baud rate?[/quote]
&lt;p&gt;The&amp;nbsp;&lt;a href="https://github.com/nrfconnect/sdk-nrf/blob/v2.9.0/samples/bluetooth/direct_test_mode/boards/nrf54l15dk_nrf54l10_cpuapp.overlay#L15"&gt;default baudrate is&amp;nbsp;19200&lt;/a&gt;.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: BLE measurements nRF54L15</title><link>https://devzone.nordicsemi.com/thread/530241?ContentTypeID=1</link><pubDate>Wed, 02 Apr 2025 12:46:33 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:43a3ffca-e1d3-4ec5-a355-b810be3b2f7d</guid><dc:creator>Hans Erik Gram</dc:creator><description>&lt;p&gt;Hi J&amp;oslash;rgen&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Sorry for late reply. Yes I know the Receiver Tap.&lt;/p&gt;
&lt;p&gt;So if I set it in DTM mode, I can do my receiver&amp;nbsp;test ?&amp;nbsp; &amp;nbsp; Do you know which IO pin on the nRF54L15-PDK bord which is UART?&amp;nbsp; &amp;nbsp;As weel what is the baud rate?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Br Hans Erik&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;

&lt;p&gt;To setup a receiver test in the DTM app in nRF Connect for Desktop, you need to go to the &amp;quot;RECEIVER&amp;quot; tab:&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1739189065252v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;From there, you can configure the channel, PHY, etc. and start the test.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;br /&gt;Jørgen&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
