https://devzone.nordicsemi.com/f/nordic-q-a/23463/using-nrf52-dk-as-ble-controller-on-an-older-kernel-hostHello, recently I was going through this and the following statement concerns me: First of all make sure you have a recent Linux kernel installed (at least 4.6) and a modern (5.42+) version of the BlueZ userspace tools.

To achieve this you can either join the IRC channel #zephyrproject on freenode.net or send an email to the zephyr-devel mailing list.
