# README for the Hello World Zephyr Application

## Overview

This is a minimal Hello World application built using the Zephyr RTOS. The application demonstrates basic logging functionality by printing a message every 5 seconds, including the version number of the application.

## Project Structure

The project consists of the following files:

- `src/main.c`: The entry point of the application that initializes logging and sets up a timer.
- `include/app_version.h`: Header file that defines the application version.
- `VERSION`: A text file containing the version number of the application.
- `prj.conf`: Configuration file for the Zephyr project, specifying necessary options.
- `CMakeLists.txt`: Build configuration file for CMake.
- `README.md`: Documentation for the project.

## Building the Application

To build the application, follow these steps:

1. Ensure you have the Zephyr development environment set up.
2. Navigate to the `apps/gateway` directory.
3. Run the following command to build the application:

   ```
   west build -b <your_board> .
   ```

   Replace `<your_board>` with the appropriate board name.

## Running the Application

After building the application, you can flash it to your board using:

```
west flash
```

Once the application is running, you will see log messages printed every 5 seconds, including the version number.

## Version

The version of this application can be found in the `VERSION` file and is also included in the log messages.
