Nordic has recently contributed support for the 2Mbit/s PHY, part of the Bluetooth 5.0 specification, to the Zephyr Project RTOS.
The video below shows how to configure, build and test GATT data throughput on a nRF52840 SoC running Zephyr RTOS.
The throughput measured may vary depending on the environment, but the maximum throughput observed in this video is around 1398 Kbps. Feel free to try it out yourself and join us with feedback and contributions to the Open Source project.
Our initial blog post about the Zephyr Project, complete with instructions to set up a Zephyr environment to try it out, can be found here.
