bluetooth_le CLI example

A pure-Dart command-line demo of bluetooth_le — no Flutter required.

dart pub get
dart run bin/ble.dart doctor                 # adapter state / support check
dart run bin/ble.dart scan                   # scan for advertising devices
dart run bin/ble.dart scan --service 6e400001-b5a3-f393-e0a9-e50e24dcca9e
dart run bin/ble.dart connect <DEVICE-ID>    # open as a serial link (Nordic UART)

<DEVICE-ID> is what scan prints — a MAC address on Linux/Windows, or an opaque identifier on macOS. connect discovers services, treats a write+notify characteristic pair as a serial channel (Nordic UART by default; override with --service/--write/--notify), prints everything received, and sends each line you type.

On macOS, build and run as a native executable so the CoreBluetooth code asset is compiled by the build hook:

dart build cli
./build/cli/bin/ble doctor

See bin/ble.dart for the source.
