.. zephyr:code-sample:: mbox
   :name: MBOX
   :relevant-api: mbox_interface

   Perform inter-processor mailbox communication using the MBOX API.

Overview
********

This sample demonstrates how to use the :ref:`MBOX API <mbox_api>`.

Building and Running
********************

The sample can be built and executed on boards supporting MBOX.

Building the application for nrf5340dk_nrf5340_cpuapp
*****************************************************

.. zephyr-app-commands::
   :zephyr-app: samples/drivers/mbox/
   :board: nrf5340dk_nrf5340_cpuapp
   :goals: debug

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 the application (APP) core another is the network (NET)
core:
