.. zephyr:code-sample:: ipc-static-vrings
:name: IPC service: static vrings backend
:relevant-api: ipc
Send messages between two cores using the IPC service and static vrings backend.
Overview
********
This application demonstrates how to use IPC Service and the static vrings
backend with Zephyr. It is designed to demonstrate how to integrate it with
Zephyr both from a build perspective and code.

Open a serial terminal (minicom, putty, etc.) and connect the board with the
following settings:
- Speed: 115200
- Data: 8 bits
- Parity: None
- Stop bits: 1
Reset the board and the following message will appear on the corresponding
serial port, one is host another is remote:
