 I am using nrf52840 costume board. and using NUS ( Nordic Uart Service ) as the basic start sample. 
 My desire: 
 1. UART0 and UART1 work in async mode with DMA 
 2. SPI for external flash 
 3. I2C for external sensor 
 4.

&lt;p&gt;I could not see that config in the page you have linked&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/pastedimage1720729330792v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;Also, I could not see that config by searching in the KCONFIG Reference page&lt;/p&gt;

&lt;p&gt;Did you try with the UART sample from the DevAcademy that I linked in my previous response?&lt;/p&gt;

&lt;p&gt;I am using SDK 2.5.2&lt;/p&gt;
&lt;p&gt;and you can find&amp;nbsp;&lt;span&gt;CONFIG_BT_NUS_UART_ASYNC_ADAPTER in the&amp;nbsp;&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span&gt;&lt;a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/peripheral_uart/README.html"&gt;docs.nordicsemi.com/.../README.html&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: UART with DMA and use PM to enable the LOWPOWER mode</title><link>https://devzone.nordicsemi.com/thread/493102?ContentTypeID=1</link><pubDate>Wed, 10 Jul 2024 09:26:20 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:2c0b3a2f-efae-4350-9ebd-5d3391693e84</guid><dc:creator>Naeem Maroof</dc:creator><description>&lt;p&gt;Hi Reza,&lt;/p&gt;
&lt;p&gt;Which SDK version you are using?&amp;nbsp;&lt;/p&gt;
&lt;p&gt;I am not able to see the config&amp;nbsp;&lt;span&gt;CONFIG_BT_NUS_UART_ASYNC_ADAPTER&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;As you want to use the UART with ASYNC API and using the DMA,&amp;nbsp;here is exactly what you are trying to do:&lt;/p&gt;
