SoftDevices

A SoftDevice is a wireless protocol stack that complements an nRF5 Series System on Chip (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.
