Beacons

A mini-project that explores Bluetooth beacon technology to detect nearby devices and enable proximity-based interactions.

🧠 Project Overview

This project was developed as a Master's mini-assignment but is worth highlighting due to the growing relevance of beacon technology in real-world applications. Beacons are especially useful in indoor environments where GPS is less effective—such as museums, shopping malls, or hospitals—providing contextual information or triggering events based on user proximity.

📍 How It Works

The app was designed to:

• Detect BLE (Bluetooth Low Energy) beacons in the surrounding area.
• Identify the proximity and signal strength of each beacon.
• Trigger simple actions or notifications based on closeness (e.g., entering or leaving a defined radius).

Although the logic and interaction were kept simple, the core functionality demonstrated the potential of beacon-driven user experiences.

🛠️ Technologies Used

• Core Location (iOS): For ranging and monitoring iBeacons.
• Bluetooth LE (BLE): For communication with nearby devices.
• Swift: For the entire iOS development process.
• Xcode Simulators + Beacon Emulators: Used for testing signal strength and behavior without physical hardware.

🚀 What Did I Learn?

• How to detect and interact with BLE devices using native iOS tools.
• The differences between ranging and monitoring in beacon tracking.
• Basic concepts of indoor positioning systems (IPS).
• How to handle background updates and power efficiency when scanning for beacons.

🎯 Final Thoughts

Even though this was a small-scale project, it opened the door to countless possibilities with location-aware mobile experiences. From interactive museum guides to indoor navigation and retail engagement systems, this project forms a solid foundation for future developments involving beacons and proximity technology.
