Expo Zebra Barcode Data Intent

Access barcode data from embedded barcode scanners on Zebra devices via DataWedge intent broadcast.
✅ Works on Android Zebra devices (e.g., ET45, etc.)

⚙️ DataWedge Profile Requirement (Important)

❗ Zebra devices use DataWedge to manage barcode scanning behavior.
This module does not auto-create or configure a DataWedge profile.
You must manually create and configure a profile on the device for it to work.

📌 Required DataWedge Settings

To enable this module to receive barcode data:

1. Open DataWedge on your Zebra device.
2. Create or edit a profile (e.g., Profile0(default)) (see the explanation of Profile0(default) below)
3. Under Intent Output:
   • ✅ Enable Intent Output
   • Intent Action: com.symbol.datawedge.api.RESULT_ACTION
   • Intent Delivery: Broadcast Intent

Without these settings, your app will not receive any scan data.

📦 Installation

npm install expo-zebra-barcode-data-intent
or
yarn add expo-zebra-barcode-data-intent

Usage

import * as ExpoZebraBarcodeDataIntent from "expo-zebra-barcode-data-intent";

useEffect(() => {
  const subscription = ExpoZebraBarcodeDataIntent.listenToScans(({ barcode }) => {
    console.log(barcode);
  });
  return () => subscription.remove();
}, []);

📋 DataWedge Profile Types (Visible Profiles)

When you open DataWedge on a Zebra device, you’ll see several visible profiles:

• Profile0 – The default profile automatically used for any app not associated with a custom profile.

  ⚠️ Since it applies globally, Profile0 cannot be directly associated with specific apps. You may disable it to prevent scanning in unconfigured apps.

• Launcher – Used when the Android launcher (home screen) is active. Not typically modified.

• DWDemo – A profile pre-configured for Zebra's demo app (DWDemo). Demonstrates scan handling via StartActivity intent. Not relevant for most custom apps.

• User-defined profiles – Custom profiles created by you.

  ✅ These profiles can and should be associated with your app to control scanning behavior.
