&lt;p&gt;There is a great blog post on maximizing throughput with BLE on&amp;nbsp;&lt;a href="https://novelbits.io/bluetooth-5-speed-maximum-throughput/"&gt;NovelBits here&lt;/a&gt;. Please note that the maximum payload with data length extensions enabled is up to 255&amp;nbsp;&lt;strong&gt;bytes&lt;/strong&gt; and not bits. What SDK are you planning on using, or are you most familiar with? We have both a &amp;quot;bare metal&amp;quot; n&lt;a href="https://infocenter.nordicsemi.com/topic/struct_sdk/struct/sdk_nrf5_latest.html"&gt;RF5 SDK &lt;/a&gt;as well as the &lt;a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.2/nrf/index.html"&gt;nRF Connect SDK&lt;/a&gt; based on the Zephyr RTOS. Both SDKs have sample projects on how to transmit and receive data with the data length extensions enabled.&lt;/p&gt;
&lt;p&gt;Best regards,&lt;/p&gt;
