https://devzone.nordicsemi.com/f/nordic-q-a/129184/buffer-overrun-nrf24l01Hi, I am using some nrf24l01s in a proof of concept (just because I have them, I know they are old). I am developing a TDM protocol for two-way radios, which requires 8000 bytes to be transmitted in 64ms. I am using 1 Mb/s and hope eventually to changeen-USTelligent Community 13Wed, 16 Sep 2026 12:12:06 GMThttps://devzone.nordicsemi.com/thread/571267?ContentTypeID=1Wed, 16 Sep 2026 12:12:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:687e7228-ba70-4f56-bc1c-42b893c6d7e3RynSmiut<p>@<a href="https://geodash.org/">geometry dash</a><br /><br />I&rsquo;d first check the CSN timing. Make sure CSN stays low for the entire <code data-start="71" data-end="87">0xB0 + 32-byte</code> transaction. Also drain the SPI RX FIFO after each transfer. The <code data-start="153" data-end="159">TFFF</code> flag only indicates TX FIFO space, not transfer completion. A logic analyzer should show each packet as <code data-start="264" data-end="295">CSN&darr; &rarr; 0xB0 &rarr; 32 bytes &rarr; CSN&uarr;</code>.<span class="PDq2pG_selectionAnchor"></span></p><div style="clear:both;"></div>
