3.2 Zephyr
Zephyr [27] is a widely adopted open-source Real Time Operating System (RTOS) that is supported
on a multitude of chipsets, including the nRF52833 chip in the NINA-B4 module. The Zephyr project
is supported by the Linux Foundation.
Nordic Semiconductor provides the nRF Connect SDK for development using the Zephyr OS, but it is
also possible to use a command-line environment for example.
3.2.1 Getting started with Zephyr on the NINA-B4 module
Follow the procedure below to get started with Zephyr:
1. Install the Toolchain Manager from the
nRF Connect for Desktop
application and from there
install the nRF Connect SDK. For more information, see reference [26] .
2. If a command line environment is preferred, see the Getting Started section on the Zephyr
website
[27] .
