https://devzone.nordicsemi.com/f/nordic-q-a/1407/what-s-the-maximum-transmission-speed-via-rfDear all I notice that Gzaell could only send 32 bytes a packet. But I check register PCNF1 MAXLEN can be set over than 32 bytes. Is there any way to increase overall transmission speed? ex: Send a packet with payload 64 bytes....en-USTelligent Community 13Tue, 21 Jan 2014 11:42:24 GMThttps://devzone.nordicsemi.com/thread/6313?ContentTypeID=1Tue, 21 Jan 2014 11:42:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df8b5dfd-75f1-4185-a023-8db941d3a9dfOle Morten<p>Gazell for nRF51 is limited to 32 bytes per payload for backwards compatibility. If you need higher throughput than it can give, you&#39;ll have to implement a custom radio protocol from the radio hardware up. You can refer to <a href="https://devzone.nordicsemi.com/documentation/nrf51/5.1.0/html/a00050.html">the official radio example in the SDK</a> for an example of how you can use the radio. <a href="https://github.com/hlnd/nrf51-simple-radio/">This GitHub repository</a> may also be useful.</p><div style="clear:both;"></div>
