4. Keep the default installation settings unless you have a specific reason to modify them.

Once the installation is complete, the JDK will be ready for use in your development environment.

Installing Python (Compatible Version for ESP-IDF)

Python is a critical dependency for ESP-IDF. It is used for build management, configuration scripts, and other internal processes within the framework.

⚠️ Important Compatibility Note:
ESP-IDF version 5.3 is not compatible with Python 3.13.
For this reason, we install Python 3.11.7, which ensures full compatibility and stable performance.

Installation Steps:

1. Visit the official Python website.

2. Download Python 3.11.7 (64-bit Windows version).

3. Run the installer.

4. ✔ Make sure to check the option: “Add Python to PATH”

5. Keep the default installation directory.

6. Click Install Now to begin installation.

When installation is complete, a confirmation message will appear indicating that setup was successful. Click Close to finish.
