    • Super configurable—tweak temperature, max tokens, system roles, and even custom headers.
    • Built to grow, with an expandable framework for adding new AI models down the road.

    Tool Calls: The Coolest Part

    Okay, let’s talk about the feature—tool calls. This is where things get really fun! With tool calls, the AI can ask your ESP32 to perform specific tasks, like reading sensor data, controlling hardware, or crunching numbers. It’s like giving your AI a direct line to your project.

    Here’s what makes tool calls so awesome:

    • Two-way street: The AI can request actions, and your ESP32 can send back results.
    • Structured data: Everything comes in neatly formatted JSON, so parsing is a snap.
    • Custom tools: You define what your ESP32 can do, and the AI will work with it.
    • Context keeper: Your conversation with the AI stays intact, even during tool interactions.

    Imagine building a weather station where the AI asks your ESP32 for real-time temperature data or a smart home device where the AI tells your ESP32 to dim the lights. The possibilities are endless!

    Why We Built This

    The ESP32 is already a powerhouse for IoT, and with ESP32_AI_Connect, we wanted to supercharge it by bringing AI into the mix. Plus, we designed it to be developer-friendly—whether you’re a seasoned coder or just starting out, this library is built to make your life easier.

  • Unlock ESP32 Web Power: Dive Deep into HTTP POST Requests with Our New Article!

    Unlock ESP32 Web Power: Dive Deep into HTTP POST Requests with Our New Article!

    Hey Makers, Learners, and Innovators!

    Exciting news from the AvantMaker team! We know many of you are harnessing the power of the ESP32 to create amazing connected projects. A core part of many IoT applications is sending data from your ESP32 to a web server – whether it’s logging sensor readings, controlling a device remotely, or interacting with an online API. Often, this involves using the HTTP POST method via the ESP32’s HTTPClient library.

    But have you ever stopped to wonder what’s really happening under the hood when you call http.POST() in your Arduino sketch? What does that data packet actually look like as it travels across the internet?

    To help demystify this crucial process, we’ve just published a brand new, in-depth tutorial page:

    Understanding How Your ESP32 Sends the HTTP POST Request

    In this new guide, we go beyond just providing example code. We take a practical ESP32 sketch that sends data to the popular testing service httpbin.org and break down:

    1. The Arduino Sketch: A quick look at the code responsible for initiating the POST request.
    2. The Raw HTTP POST Request: We reconstruct the actual data packet sent by the ESP32, line by line. You’ll learn about the request line (POST method, path, HTTP version), essential headers like Host, Content-Type, and Content-Length, the crucial blank line separator, and the formatted data payload itself.
    3. The Server’s Response: We analyze the response from httpbin.org to confirm how the server received and interpreted the data sent by your ESP32.

    Why is this important?

    Understanding the structure of HTTP requests isn’t just academic. It empowers you to:

    • Troubleshoot effectively: When your ESP32 can’t connect or send data correctly, knowing what the request should look like is key to finding the problem.
    • Interact with APIs confidently: Many web services require data to be POSTed in a specific format. Understanding the components lets you craft the correct requests.
    • Design better projects: Knowing how data is packaged and sent helps you design more efficient and reliable communication for your IoT devices.

    This new page is part of our ongoing effort to build a comprehensive collection of references and tutorials within the AvantMaker ESP32 Resources Hub, helping you turn your innovative ideas into reality.

  • ESP32-WebFS: Simplifying SPIFFS File Management for Your ESP32 Projects

    ESP32-WebFS: Simplifying SPIFFS File Management for Your ESP32 Projects

    Introducing ESP32-WebFS

    If you’ve ever worked with an ESP32 microcontroller, you’ve likely come across SPIFFS—short for Serial Peripheral Interface Flash File System. It’s like a tiny digital filing cabinet built into your ESP32, perfect for storing files like web pages, sensor data, or configuration settings. For makers, SPIFFS is a game-changer because it lets your projects do more—like serving up a webpage or saving logs—without needing extra hardware.

    ESP32 WebFS Web Interface Screenshot

    Enter ESP32-WebFS, a fresh tool from the AvantMaker Team. It turns your ESP32 into a web server with a simple but not simplistic interface, making it a breeze to upload and manage files on SPIFFS. No more fumbling with complicated setups—just a straightforward way to keep your projects organized. Best of all? It’s open-source under the MIT license. That means it’s free to use, modify, and share, with no hidden costs or restrictions. The MIT license is a promise that this tool is yours to explore, hassle-free.

    Why We Created ESP32-WebFS

    Let’s face it: managing files on an ESP32’s SPIFFS can feel like trying to herd cats. Normally, you’d need to hook up your board, use specific software, and sometimes even dig into command-line tools to get files where they need to be. It’s time-consuming, error-prone, and not exactly beginner-friendly. We’ve been there, and we knew there had to be a better way.

    That’s why we at AvantMaker built ESP32-WebFS. Our goal was simple: take the headache out of uploading and managing SPIFFS files. With this tool, you can handle everything through a web browser, cutting out the extra steps and letting you focus on what matters—building cool projects.

    What ESP32-WebFS Brings to the Table

    ESP32-WebFS comes packed with features designed to simplify your workflow:

    • Web-Based File Management: Upload, delete, download, view files on SPIFFS using a simple browser interface—no extra software needed.
    • Easy Setup: Get started fast—just update the Wi-Fi credentials in the sketch, upload it to your ESP32, and your board is ready to roll.
    • Real-Time Feedback: See what’s happening with your files as you work, with updates right on the screen.
    • Lightweight Design: It’s built to run smoothly on the ESP32 without eating up all your memory or processing power.
    • Customizable Code: Since it’s an Arduino sketch, you can tweak it to fit your project’s needs.

    Practical Use Cases:

    • Remote Configuration: Easily update configuration files for your IoT devices deployed in hard-to-reach locations without physical access.
    • Data Logging Retrieval: Wirelessly download sensor data logs stored on the ESP32 SPIFFS for analysis and visualization.
    • Custom Web Interface Updates: Quickly update the HTML, CSS, and JavaScript files for your ESP32-powered web applications.

    Where to Grab ESP32-WebFS

    Ready to experience the ease of managing your ESP32’s SPIFFS files? ESP32-WebFS is now available on the AvantMaker GitHub repository! Head over to the link below to get the code and start using it in your projects:

    https://github.com/AvantMaker/ESP32-WebFS

    It’s all there, free and open for you to explore. Since it’s open-source, we’d love to hear your feedback or see your contributions—feel free to fork the project and share your ideas to make it even better!

    Setting Up and Using ESP32-WebFS: A Quick Guide
