React Native Honeywell Scanner SDK With Soft Trigger

**This package is using honeywell react native module built from Source

This package works with Honeywell devices that have an integrated barcode scanner, like the Honeywell Dolphin CT40. This package was fully tested with a CT40, since the SDK is not specific to the CT40 other devices will likely work as well but this is not guaranteed.

Prerequisites

To install the dependencies:

npm install

Ensure that the sdk.dir path is set up in the system environment variable or add local.properties inside android directory and add the below

sdk.dir=<Path>/Android/sdk

Usage

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

import HoneywellScanner from 'react-native-honeywell-scanner-trigger';

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:

useEffect(() => {
    if (isCompatible) {
      HoneywellScanner.startReader().then(claimed => {
        console.log(
          deviceClaimed
            ? 'Barcode reader is claimed'
            : 'Barcode reader is busy',
        );
        HoneywellScanner.onBarcodeReadSuccess(event => {
          console.log('Received data', event.propogated);
        });

        HoneywellScanner.onBarcodeReadFail(event => {
          console.log('Barcode read failed');
        });
      });

      return () => {
        HoneywellScanner.stopReader().then(() => {
          console.log('Stop Reader!!');
          HoneywellScanner.offBarcodeReadSuccess();
          HoneywellScanner.offBarcodeReadFail();
        });
      };
    }
  }, [isCompatible]);

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.onBarcodeReadSuccess(event => {
    console.log('Barcode Scan data', event.data);
    console.log('Barcode Scan Timestamp', event.timeStamp);
    console.log('Barcode Scan Type', event.symbology);
});

HoneywellScanner.onBarcodeReadFail(event => {
    console.log('Barcode read failed');
});

To stop receiving events:

HoneywellScanner.offBarcodeReadSuccess();
HoneywellScanner.offBarcodeReadFail();

Soft Trigger handling via Scan button

HoneywellScanner.softwareTriggerStart((error, name) => {
      setApiErrorMessage(error != null ? error : name);
    });
setTimeout(() => {
      HoneywellScanner.softwareTriggerStop((error, name) => {
        setApiErrorMessage(error != null ? error : name);
      });
}, 2000);
