IoT Controller Firmware Update via Web Interface

This firmware enables Over-The-Air (OTA) updates for an IoT controller using a web interface. It allows you to upload firmware files to the controller without the need for physical access.

Features

  • Web Interface: Provides a simple web interface for uploading firmware files.
  • Authentication: Implements a basic authentication mechanism for accessing the update page.
  • OTA Update: Enables Over-The-Air updates for the IoT controller firmware.

Setup Instructions

To use this firmware for your IoT controller, follow these steps:

  1. Requirements:

    • ESP32 board compatible with the Arduino framework.
    • WiFi network credentials.

  2. Installation:

    • Clone or download this repository to your local machine.

  3. Configuration:

    • Open the OTA_Controller.ino file in the Arduino IDE or any compatible editor.
    • Modify the ssid and password variables to match your WiFi network credentials.
    • Optionally, you can change the host variable to set a custom hostname for the device.

  4. Upload Firmware:

    • Connect your ESP32 board to your computer.
    • Compile and upload the firmware to your ESP32 board.

  5. Usage:

    • Once the firmware is uploaded, the ESP32 will create an access point with the configured SSID.
    • Connect your computer or smartphone to this access point.
    • Open a web browser and navigate to http://Novaday.local (replace Novaday with the configured hostname).
    • You will be prompted to enter a username and password. The default credentials are admin for both username and password.
    • After successful authentication, you can upload firmware files using the provided interface.

  6. OTA Update:

    • Select the firmware file using the "Choose file..." button.
    • Click the "Update" button to initiate the firmware update process.
    • Monitor the progress bar to track the update process.
    • Once the update is complete, the device will automatically reboot with the new firmware.

Important Notes

  • Ensure that your firmware files are compatible with the ESP32 platform and follow the required format.
  • It's recommended to test the firmware update process in a controlled environment before deploying it in production.
  • Always secure your device by changing the default credentials and implementing additional security measures as needed.
