nRF BLE Controller
==================

| The nRF BLE Controller is an RTOS-agnostic library built for the Nordic
  Semiconductor nRF52 and nRF53 Series that supports Bluetooth 5.
| In addition to providing a BLE HCI interface, it also provides:

-  Multiprotocol support through APIs for requesting RADIO timeslots,
-  APIs for accessing flash memory concurrently with radio activity,
-  APIs for controlling the high frequency clock.

| The nRF BLE Controller is distributed in different variants containing
  different features.
| All variants are available as soft-float, softfp-float, and hard-float
  builds.
