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.
