What transmitting over the air is including the address, preamble, overhead,CRC etc, not just the payload. In addition, I&#39;m not sure if the code the tester used was just transmitting or it&#39;s including ACK ? Also the DUT didn&#39;t send the packet as fast as possible but has some delay between packet. If you send bigger payload size = 32bytes, you will be able to reduce the proportion of the overhead.</p> <p>Please be aware, the nRF24 requires the radio be disabled and re-enabled after every 4ms of transmitting. You may take this into account when you try to maximize transmission rate. By theory we can achieve around 190kbps actual rate with the 250kbps mode.</p><div style="clear:both;"></div>
