Usage

First you'll want to check whether the device is a Honeywell scanner:

import HoneywellBarcodeReader from "honeywell-todoboletos-qr";

HoneywellBarcodeReader.isCompatible; // true or false

The barcode reader needs to be "claimed" by your application; meanwhile no other application can use it. You can do that like this:

HoneywellBarcodeReader.startReader().then((claimed) => {
  console.log(claimed ? "Barcode reader is claimed" : "Barcode reader is busy");
});

To get events from the barcode scanner:

HoneywellBarcodeReader.onBarcodeReadSuccess((event) => {
  console.log("Received data", event);
});

HoneywellBarcodeReader.onBarcodeReadFail(() => {
  console.log("Barcode read failed");
});

To free the claim and stop the reader, also freeing up resources:

HoneywellBarcodeReader.stopReader().then(() => {
  console.log("Freedom!");
});

To stop receiving events:

HoneywellBarcodeReader.offBarcodeReadSuccess();
HoneywellBarcodeReader.offBarcodeReadFail();
