Experience seamless and secure access control with the Smart Lock application, developed by CionLabs. Designed for modern IoT locker systems, this app provides a robust interface to interact with your hardware using industry-standard protocols. Whether you are troubleshooting a connection or accessing your personal locker, Smart Lock offers the flexibility of dual-mode connectivity through Bluetooth Low Energy (BLE) and USB OTG Serial.

Key Features:

⚡ Dual Connectivity Modes Smart Lock ensures you can always connect to your device, regardless of the environment:

1. Bluetooth LE (Wireless):

> Smart Scanning: Automatically filters and finds nearby "SMART_LOCKER" devices.
> Low Latency: Uses optimized GATT connections for fast data exchange.
> Real-time Feedback: View connection status, signal strength, and service discovery instantly.

2. USB Serial (Wired):

> Broad Compatibility: Supports major USB-to-Serial chips including FTDI, Silabs, Prolific, and CH34x.
> Custom Driver Support: Includes a custom Prober for proprietary hardware.
> Direct Link: Perfect for high-interference environments where wireless is not an option.

🔑 OTP-Based Access Control Forget physical keys. Smart Lock uses a dynamic One-Time Password (OTP) challenge-response system to ensure only authorized users can unlock the door.

> Receive Challenge: The locker generates a random 6-digit code displayed directly in the app.
> Verify & Unlock: Enter your OTP to instantly trigger the unlocking mechanism.
> Visual Confirmation: Receive immediate visual and haptic feedback upon a successful unlock with our "Access Granted" animations.

📱 Modern & Intuitive UI Built with Jetpack Compose, the app features a sleek, futuristic interface:

> Glassmorphism Design: A premium aesthetic with frosted glass elements and neon accents.
> Dark & Light Modes: Optimized for visibility in any lighting condition.
> Smooth Animations: Fluid transitions between scanning, connecting, and success screens.

How It Works:

1. Log In: Authenticate securely to access the main dashboard.
2. Select Mode: Choose between Bluetooth or USB Serial based on your proximity and hardware setup.
3. Connect: Tap to pair with your specific locker unit.
4. Unlock: View the device code, enter your OTP, and wait for the "Access Granted" confirmation.

Technical Requirements:

> Android 8.0 (Oreo) or higher.
> Bluetooth 4.0+ (for BLE mode).
> USB OTG support (for USB mode).
> Internet connection (for initial Login/Registration).
