Broadcast-Event-Listener

You can enable Output Via Broadcast option in your SUNMI Device Scanner's Settings and then listen the onScanSuccess Event with the result. You have to use physical special key buttons on your SUNMI device or soft floating button on your device (if you enabled that) to trigger infrared scanning for the barcodes . And then afterwards , you can get the result in the onScanSuccess event.

useEffect(() => {
  DeviceEventEmitter.addListener('onScanSuccess', (msg) => {
    console.log('result', msg);
  });
  return () => DeviceEventEmitter.removeAllListeners('onScanSuccess');
}, []);
