The Zephyr OS project is a compact, multi-threaded, open-source operating system designed for IoT applications. Its small footprint and connectivity make it ideal for resource-constrained environments like wearable applications as well as commercial and industrial applications requiring security.
Zephyr offers lots of flexibility. For example, it supports multiple scheduling and queueing strategies. It uses devicetree to describe resources. And there's built-in support for networking, including Bluetooth Low Energy (BLE) 5.0.
The Zephyr OS is important as it provides a common platform for IoT applications that can work together and with the cloud. Support and functionality are similar to Linux, but in a scaled-down solution that can fit on microcontrollers. Also in the mix are code portability and middleware that developers can utilize on a range of hardware. It also has broad vendor and community support.
