bluetoothManager.state.listen((state) {
switch (state) {
case BluetoothManager.CONNECTED:
// ...
break;
case BluetoothManager.DISCONNECTED:
// ...
break;
default:
break;
}
});
// bluetoothManager.scanResults is a Stream<List<BluetoothDevice>> sending the found devices.
// _device = <from bluetoothManager.scanResults>
await bluetoothManager.connect(_device);
List<int> bytes = latin1.encode('Hello world!\n').toList();
