Requirements

The nRF Connect SDK supports Microsoft Windows, Linux, and macOS for development. However, there are some Zephyr features that are currently only available on Linux, including:

• sanitycheck

• BlueZ integration

• net-tools integration

Note

Before you start setting up the toolchain, install available updates for your operating system.
