You want to send 156 bytes of data every 1ms which means ~1.25Mbps. That&#39;s on the edge of what BT5.0 can achieve with 2Mbps link data rate and all possible optimizations (see <a href="https://devzone.nordicsemi.com/blogs/1078/throughput-and-long-range-demo/">this blog post</a>). My personal guess is that you would never make it work reliably at this throughput. You might be able to achieve it with nRF52840 and custom radio protocol (not BLE) but then my question would be why to choose low power radio chip when your application is clearly high-throughput &quot;streaming like&quot; beast.</p> <p>Cheers Jan</p><div style="clear:both;"></div>
