To decouple Zephyr modules and propagate changes, define a Zbus channel for event-driven communication. This allows independent modules to publish and subscribe to data without direct coupling, enabling scalable and feature-rich embedded architectures.

Managing hierarchical state machines in Zephyr is best handled by the State Machine Framework (SMF). SMF provides clear lifecycles and transitions, allowing developers to coordinate complex application modes and workflows reliably.

To offload background processing in Zephyr and prevent main thread blocking, use k_work queues. This work-queue mechanism allows you to defer non-critical tasks, ensuring event-driven modules remain responsive.

Yes, you can combine Zbus, SMF, and settings in a single Zephyr application. This modular orchestration allows sensors to publish data via Zbus, SMF to coordinate modes, and settings to persist calibration data across reboots.

Yes, this approach suits scalable embedded applications with complex workflows. By enforcing Zephyr APIs like zbus, smf, k_work, and settings, it supports event-driven modules, hierarchical state machines, and reliable non-volatile settings.
