React Native Honeywell Scanner

This package is not maintained! This fork might work better.

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.
