BLE Peripheral macOS App

Project Summary

• A macOS app built with Swift, Cocoa (AppKit), and CoreBluetooth.
• Acts as a BLE Peripheral that advertises a custom GATT service.
• Defines two characteristics:
  • rxCharacteristic (notify) to send data to a connected central.
  • txCharacteristic (writeWithoutResponse) to receive data from a central.
• Advertising is manually triggered via a user interface button.
• Stops advertising once a central subscribes to the notify characteristic.
• Allows users to input and send messages through the GUI.
• Displays a real-time debug log in the interface using NSTextField.
• Handles Bluetooth state updates, subscriptions, and data exchange.
