https://devzone.nordicsemi.com/f/nordic-q-a/33745/stand-alone-ble-controller-variant-of-its-softdevice-protocol-stackHi, Why doesn&#39;t Nordic offer a stand-alone BLE controller variant of its softdevice protocol stack? As far as I understand, the softdevices includes both Host and Controller.

The SoftDevice aims at providing a GAP/GATT interface to the user/application which is ideal for single-chip configurations.
