NORDIC 사 SoftDevice  설명. 

SoftDevices are precompiled and linked binary software implementing Bluetooth low energy and ANT wireless protocols. SoftDevices reduce compile-time dependences for application developers working on their applications. The hardware and software framework provides run-time isolation and determinism in its behavior. These characteristics make the interface comparable to a hardware peripheral abstraction with a functional, programmatic interface.

The SoftDevice Application Programming Interface (API) is available to applications as a high-level programming language interface such as a C header file.

The nRF52840 is supported by the S140 SoftDevice multi-role, concurrent Bluetooth low energy protocol stack. S140 SoftDevice is designed for Bluetooth 5 and its new features.

SoftDevice 는 nRF5 SDK 다운로드 하면 같이 포함되어 배포되나, SDK 버전은 그대로이면서 SoftDeivce 만 버전 업 된 경우 별도 다운로드 받아야 한다.
