CPU --&gt; nRF24L01 --(2.4GHz/1Mbps)--&gt; nRF24L01 --&gt; CPU CPU --&gt; nRF24LE1 --(2.4GHz/1Mbps)--&gt; nRF24LE1 --&gt; CPU Transmission Speed = 1Mbps,en-USTelligent Community 13Mon, 08 Feb 2016 10:19:15 GMThttps://devzone.nordicsemi.com/thread/44303?ContentTypeID=1Mon, 08 Feb 2016 10:19:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fc714662-e9a1-40ae-8e76-dc05523934c2Kenneth<p>Hi, I don&#39;t expect any difference using nRF24L01 or nRF24LE1, it might be slightly slower using nRF24LE1 as data must be buffered. For highest speed you should consider 2Mbps instead of 1Mbps, so I have made some rough calculations here using 2Mbps:</p> <p>Write data over SPI: 70us Startup radio: 130us Transmit data: 160us (or 320us with 1Mbps) Read out data over SPI: 70us</p> <p>Total: 430us (or 590us with 1Mbps)</p><div style="clear:both;"></div>
