 I have been trying out the SDK 15.2 DFU using serial / usb serial based on this

&lt;p&gt;If you connect a debugger, and use the nRF Connect for Desktop Programmer app, you can read the SoftDevice version that is flashed to the chip.&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;
&lt;p&gt;the following command was used to generate the pkg&lt;/p&gt;
&lt;p&gt;nrfutil pkg generate --hw-version 52 --application-version 1 --application hrs_application_s140.hex --sd-req 0xAE --key-file private.key app_dfu_package.zip&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;FYI, i am using a 3rd party nrf52840 board for all the testing. details as follows.&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;

&lt;p&gt;What command did you use to generate the DFU package ? From the error-code it looks like you forgot to use&amp;nbsp;--sd-req , or that you provided the wrong&amp;nbsp;--sd-req value.&lt;/p&gt;
&lt;p&gt;By default, &lt;a href="https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52840/COMP/nrf52840/nRF52840_ic_rev_sdk_sd_comp_matrix.html"&gt;SDK 15.2 uses&amp;nbsp;&lt;/a&gt;&lt;span&gt;&lt;a href="https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52840/COMP/nrf52840/nRF52840_ic_rev_sdk_sd_comp_matrix.html"&gt;s140_nrf52_6.1.0&lt;/a&gt;, so try using&amp;nbsp;--sd-req&amp;nbsp;0xAE when &lt;a href="https://github.com/NordicSemiconductor/pc-nrfutil/tree/v6.0.0#generate"&gt;generating the package&lt;/a&gt;&amp;nbsp;with&amp;nbsp;nrfutil pkg generate&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
