IoT Controller Firmware with Bluetooth Configuration and OTA Update

This firmware provides functionality for an IoT controller, including Bluetooth configuration and Over-The-Air (OTA) updates. It allows users to configure WiFi credentials via Bluetooth and update the firmware wirelessly.

Features

• Bluetooth Configuration: Enables configuration of WiFi credentials via Bluetooth communication.
• OTA Update: Supports Over-The-Air updates for the firmware, allowing easy maintenance and upgrades.
• Web Interface: Provides a web interface for firmware updates using HTTP POST requests.
• Authentication: Implements basic authentication for accessing the web interface.

Setup Instructions

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

1. Requirements:

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

2. Installation:

   • Clone or download this repository to your local machine.

3. Configuration:

   • Open the PAT_OTA.h file and modify the ssid and password variables to match your WiFi network credentials.
   • Optionally, adjust the host variable to set a custom hostname for the device.
   • Configure the Bluetooth device name by modifying the device_name variable in the PAT_Bluetooth.h file.

4. Upload Firmware:

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

5. Bluetooth Configuration:

   • Pair your Bluetooth-enabled device with the ESP32 using the device name specified in the configuration.
   • Use a terminal emulator or Bluetooth app to send commands for WiFi configuration:
     • To set the SSID, send wlan0 <your_ssid>.
     • To set the password, send pass <your_password>.
     • Restart the WiFi connection by sending restart wlan0.

6. Web Interface for OTA Update:

   • Once connected to the WiFi network, open a web browser and navigate to the device's IP address or hostname (e.g., http://Novaday.local).
   • Use the provided web interface to upload firmware files for OTA updates.

Important Notes

• Ensure that your firmware files are compatible with the ESP32 platform and follow the required format.
• Make sure to secure your device by changing the default credentials and implementing additional security measures as needed.
• Test the firmware update process in a controlled environment before deploying it in production to ensure reliability.
