ESP32 project for wearable smart glasses that display notifications, calls, messages, time, and more on an integrated OLED display.

This project implements a firmware for smart glasses based on the ESP32-C3 microcontroller. It establishes a Bluetooth Low Energy (BLE5) connection with a smartphone and displays relevant information such as:

• ⏰ Time and date
• 📞 Incoming calls and caller information
• 💬 Text messages
• 📝 Custom text notifications
• ⏱️ Timer functionality

• 📊 Multimeter values
• 🛰️ GPS display
• 🎮 Simple games
• 🎵 Music controls

• Microcontroller: ESP32-C3
• Display: SSD1306 OLED (128x64)
• Connectivity: Bluetooth Low Energy 5.0
• I2C Configuration:
  • SDA Pin: 2
  • SCL Pin: 3

The companion Android app connects to the smart glasses via BLE and provides:

• ⏰ Time synchronization
• 📞 Calls info to glasses
• 💬 Message notifications
• ⏱️ Timer controls

1. Build the firmware:

   • Install PlatformIO
   • Build and upload to your ESP32-C3 device

2. Install the Android app:

   • Install the provided APK on your smartphone
   • Enable Bluetooth and connect to the smart glasses
   • You can also use the .aia file on the MIT App Inventor website (ai2.appinventor.mit.edu) to edit the app and add your own features
