📟 BikeNavESP32 Dashboard

A high-performance, real-time navigation dashboard for motorcycles and bicycles. This project acts as the physical interface for the BikeNav ecosystem, receiving and visualizing telemetry and guidance data from the Android Companion app via low-latency BLE.

🌌 Features

• Real-time Navigation: Synchronized turn-by-turn guidance with maneuver icons, distance, and ETA.
• Smart Speedometer: Integrated speed display with visual safety alerts:
  • Blue: Normal speeds (< 55 km/h)
  • Orange: Caution threshold (55 - 70 km/h)
  • Red: Danger/High-speed threshold (> 70 km/h)
• Phone Health Monitoring: Live sync of phone battery percentage (🔋) and signal strength (📶).
• Communication Hub: Incoming call notifications with caller ID and remote accept/decline actions.
• Context Awareness: "Smart Throttling" support to maximize battery life during cruising.

🛠️ Hardware Stack

• MCU: ESP32 (38-pin DevKit recommended)
• Display: 3.5" TFT with ST7796 Driver (320x480 resolution)
• Touch: Capacitive or Resistive touch controller support
• UI Framework: LVGL v8.3

1. Download BikeNav_vx.x_Full.bin from releases.
2. Use a web flasher like ESP Web Flasher.
3. Set the flashing address to 0x0.
4. Flash and Reboot.

Development Setup (PlatformIO)

1. Install PlatformIO IDE.
2. Clone this repository.
3. Adjust platformio.ini if using different pin configurations.
4. Build and Upload:

   pio run -t upload

📡 Protocol

The system communicates via BLE using a lightweight JSON schema.

{
  "nav": {
    "m": "Maneuver_ID",
    "d": "Distance",
    "t": "ETA"
  },
  "speed": "65",
  "bat": 85,
  "sig": 4
}

🤝 System Architecture

This project is part of a dual-component system. To function correctly, it must be paired with the BikeNavMobile companion android application.
