(The wireless-communication works successfully ). The following ( 420us+200us ), accompany only 32-byte wireless-transmission, which means the real-rate is only 412 Kbps .

As you can see from the comments it should take about 78us to write a 32 byte payload from XDATA memory in the nRF24LE1:</p> <p><a href="https://devzone.nordicsemi.com/cfs-file/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-d30ec3e9e5724883b74ea5c6dffad065/Quick-shockburst.zip">Quick shockburst.zip</a></p> <p>I also experimented with assembly code to get it even quicker, but for most applications I think the example above is sufficient, and easier to integrate.&nbsp;</p> <p>Best regards<br />Torbjørn</p> <p></p><div style="clear:both;"></div>
