https://devzone.nordicsemi.com/f/nordic-q-a/26168/data-rate-of-nrf24l01pHello Sir, I’ve been used nRF24L01P controlled by DSP to transmit and receive data for few months. The nRF24L01P is run in 1Mbps mode. The SPI of DSP is set to send 8 bits each time, and it’s Baud rate is 1M. However, it’s practical data rate is loooooweren-USTelligent Community 13Tue, 24 Oct 2017 10:22:43 GMThttps://devzone.nordicsemi.com/thread/103088?ContentTypeID=1Tue, 24 Oct 2017 10:22:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6be38cec-24dd-42a6-8259-b87a1ff9c6d8Hung Bui<p>Hi Joker,</p> <p>As a rule of thumb, the larger the packet sending over the air, the lower the overhead and less gap period. If you send only 2 bytes the through put will reduce quite a lot. If you are using ESB, you should use 32 bytes payload. You can group several sample data into one payload and send when you have 32 bytes. Note that, long packet over the air has a cons that there is more chance the packet get corrupted because of interference and the whole packet have to be re-transmitted but it&#39;s not a big deal with 32 bytes payload (+overhead).</p> <p>The maximum data rate, you can refer <a href="https://devzone.nordicsemi.com/question/4088/whats-the-maximum-datarate-of-nrf24l01/">here</a>.</p> <p>Another note, the on-air data rate is 1Mbps. This doesn&#39;t mean the actual data rate is 1Mbps, interference, ramping up time, switching time, overhead will reduce the actual through put.</p><div style="clear:both;"></div>
