In this tutorial, we build a simple but practical web application that demonstrates how BleuIO can be integrated with a modern web framework to interact with Bluetooth Low Energy (BLE) devices in real time. The goal of this project is not to create a full-featured product, but to provide a clear example that developers can learn from and extend for their own use cases.

The application connects to a BleuIO USB dongle via a serial port, enables verbose mode, performs a BLE scan, and detects whether a specific nearby BLE device is present. If the target device is found, the application displays its MAC address. This approach is particularly useful for scenarios such as proximity detection, presence monitoring, or gateway-style BLE integrations.

The complete source code for this project is provided separately so developers can easily clone, modify, and build upon it.
