Nordic nRF5 Series: nRF52 User Manual

SoftDevices
A SoftDevice is a wireless protocol stack that complements an nRF5 Series SoC. Nordic Semiconductor
provides them as qualified, precompiled binary files. While it is possible to build applications without
using a SoftDevice, all nRF5 SDK example applications that use Bluetooth Low Energy or ANT
™
require a
SoftDevice.
See the compatibility matrices for detailed information about which SoftDevice versions are supported for
each chip. The following table summarizes the usage scenarios for each SoftDevice.
