BluetoothManager class

Manages Bluetooth operations such as device discovery, connection, disconnection, and streaming data for BLE devices.

This class is responsible for handling all the Bluetooth-related operations and can be injected as a lazy singleton using a dependency injection system.

It is recommended that you access this class via the OptiConnect class and avoid direct initialization.
