URP core example

Discover and connect to a reader over any transport.

Future<void> main() async {
  // Scan USB and Bluetooth at once; connect over whichever finds the reader.
  final strategy = CompositeConnectionStrategy([
    UrpUsbStrategy(),
    UrpBleStrategy(),
  ]);

  await for (final device in strategy.findDevices({UrpDeviceType.urpImz})) {

  }

  final connected = await strategy.findAndConnectDevice(
    readerTypes: {UrpDeviceType.urpImz},
  );

    // isWired distinguishes a cabled reader, which is unambiguously the one
    // the user plugged in, from a wireless one that could be any nearby unit.
    print('connected over ${strategy.activeTransportName}, wired=${strategy.isWired}');
    await strategy.disconnectDevice();
