 Zephyr 3.0 , nrf5340 ncs 1.9.1 
 i can successfully sent data with 
 
 this function ; 
 
 
 So it sends 2 transactions without changing cs state. 
 1byte tx+rx , and remaining rx bytes at the second transaction.. all works as expected.

&lt;p&gt;I have attached the project here:&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/5432.spi_5F00_test.zip"&gt;devzone.nordicsemi.com/.../5432.spi_5F00_test.zip&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;It is basically just the zephyr blinky sample, with some code added to test the SPI driver.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;It was tested in v1.9.1.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you are still having problems getting it to build or run please let me know which issues you&amp;#39;re seeing, and I will do my best to help.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Best regards&lt;br /&gt;Torbjørn&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: ZEPHYR spi asynchronus api transfer with asymmetric buffers error</title><link>https://devzone.nordicsemi.com/thread/368687?ContentTypeID=1</link><pubDate>Thu, 19 May 2022 20:08:38 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:70152a58-f817-4290-9030-b437f7bfa8a1</guid><dc:creator>MCB</dc:creator><description>&lt;p&gt;Could you please give me full project , i couldnt make it work standalone.&amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: ZEPHYR spi asynchronus api transfer with asymmetric buffers error</title><link>https://devzone.nordicsemi.com/thread/368538?ContentTypeID=1</link><pubDate>Thu, 19 May 2022 08:27:41 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:6cfe8ff9-c36c-4c5c-b67c-f009859a0163</guid><dc:creator>ovrebekk</dc:creator><description>&lt;p&gt;Hi Mehmet&lt;/p&gt;
&lt;p&gt;I don&amp;#39;t seem to have any issues with this on my side. I can use the spi_transceive_async functions whether or not I have the same number of TX and RX buffers.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Please find my main.c file attached:&lt;br /&gt;&lt;a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/7115.main.c"&gt;devzone.nordicsemi.com/.../7115.main.c&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Are you sure you are setting up the poll signal and event correctly?&lt;/p&gt;
&lt;p&gt;How are you polling the signal after starting the SPI transaction?&lt;/p&gt;
&lt;p&gt;Best regards&lt;br /&gt;Torbjørn&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
