https://devzone.nordicsemi.com/f/nordic-q-a/692/packet-fragmentation-with-the-nrf24l01Hi Guys, I am planning on using the nrf24l01+ to send data with a payload which is larger than 32 bytes, I was wondering whats the fastest way to transmit these packets and receive them without wasting anytime. On the reception side I doubt there&#39;sen-USTelligent Community 13Mon, 21 Oct 2013 10:54:15 GMThttps://devzone.nordicsemi.com/thread/3476?ContentTypeID=1Mon, 21 Oct 2013 10:54:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:928387b9-7e8b-449d-872e-cb0b4ac6aa87H&#229;kon Alseth<p>Hi,</p> <p>There are some tricks to do to keep the data rate high, but this will not guarantee data integrity (no ACKing or re-transmissions). However, getting as much as 1.74 Mbit/s is highly unlikely. Remember that this is wireless, and you will always have some packet loss.</p> <p>The on-air data rate is 2 Mbit. You have overhead in your preamble, address, and configurable CRC. The lowest overhead that you can configure is 4 bytes (1 byte preamble + 3 byte address). CRC is highly recommended to enable.</p> <p>You will also have to take into account that you must start up on the PLL for the radio each 4 millisecond (start up is 130 us) in order to keep the RF carrier within specification.</p> <p>You&#39;ll need a fast MCU (ARM core or similar) to service this kind of throughput.</p> <p>If you go with the nRF24L01+, then you will have to buffer up in 32 byte chunks. If you look at the nRF51-series (nRF51822 for instance), then the radio is able to send 255 bytes per payload.</p> <p>Best regards Håkon</p><div style="clear:both;"></div>
