Note: This code is taken from https://github.com/Surile/react-native-sunmi-printer under MIT open-source license. We have just removed scanner module in order to avoid overriding of other camera library because of it.

Caution: this is not the official project. I share it because I am working on this device but no any official support in react-native It's welcome to ask any question about the usage,problems or feature required, I will support ASAP.

Offical Demos plz refer: https://github.com/shangmisunmi/SunmiPrinterDemo

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');
}, []);
