12 The :dfn:`Zephyr bus - zbus` is a lightweight and flexible software bus enabling a simple way for
13 threads to talk to one another in a many-to-many way.
21 Threads can send messages to one or more observers using zbus. It makes the many-to-many
22 communication possible. The bus implements message-passing and publish/subscribe communication
25 The communication through zbus is channel-based. Threads (or callbacks) use channels to exchange
