React Native Honeywell Scanner
This package works with Honeywell devices that have an integrated barcode scanner, like the Honeywell Dolphin CT50. This package was fully tested with a CT50, since the SDK is not specific to the CT50 other devices will likely work as well but this is not guaranteed.
Tip: Use react-native-camera as fallback for devices that don't have an integrated scanner; it has an integrated barcode scanner by using the camera.
Installation
yarn add react-native-honeywell-scanner
To install the native dependencies:
react-native link react-native-honeywell-scanner
Usage
First you'll want to check whether the device is a Honeywell scanner:
import HoneywellScanner from 'react-native-honeywell-scanner';
HoneywellScanner.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:
HoneywellScanner.startReader().then((claimed) => {
console.log(claimed ? 'Barcode reader is claimed' : 'Barcode reader is busy');
});
To free the claim and stop the reader, also freeing up resources:
HoneywellScanner.stopReader().then(() => {
console.log('Freedom!');
});
To get events from the barcode scanner:
HoneywellScanner.on('barcodeReadSuccess', event => {
console.log('Received data', event);
});
HoneywellScanner.on('barcodeReadFail', () => {
console.log('Barcode read failed');
});
To stop receiving events:
function barcodeReadFail = () => console.log('Barcode read failed');
HoneywellScanner.off('barcodeReadFail', handler);
Inspiration
The react-native-bluetooth-serial project was used as inspiration. cordova-honeywell also served as some inspiration.
