https://devzone.nordicsemi.com/f/nordic-q-a/26112/s140-sdk14-bluetooth5-test-with-nrf52840Hello, I succeeded to port s110 &amp; sdk9 to s140 &amp; sdk14 which was a problem before. What we need to do now is to compare the performance of BLE devices with s110 &amp; sdk9 (nrf51822) and bluetooth 5 devices with s140 &amp; sdk14 (nrf52840).

The nRF51 series dont have any of this. For the terms used here, I recommend taking a look at <a href="https://devzone.nordicsemi.com/blogs/1078/throughput-and-long-range-demo/">this blog post.</a>.</p> <p>You have maybe seen our youtube video called, <a href="https://www.youtube.com/watch?v=K1ItqEZ2_tw">&quot;Bluetooth 5 high throughput mode (2Mbps) demo with nRF52 Series&quot;</a>. The source code for the demo is available on Github if you want to have a look at it <a href="https://github.com/NordicPlayground/nrf52-ble-image-transfer-demo">here</a>; , and the Android code is also available <a href="https://github.com/NordicPlayground/Android-Image-Transfer-Demo">here</a>. How the throughput is measured on the Android side should be shown around <a href="https://github.com/NordicPlayground/Android-Image-Transfer-Demo/blob/e5fb1f90e126021220f78abe9138ad3536f80c17/src/com/nordicsemi/ImageTransferDemo/MainActivity.java#L366">here</a> in the code.</p><div style="clear:both;"></div>
