matthewwarnes/react-native-ble-manager-plugin

Based on @config-plugins/react-native-ble-plx

Config plugin to auto-configure react-native-ble-manager when the native code is generated (expo prebuild).

Expo installation

Version for Expo 49

This package cannot be used in the "Expo Go" app because it requires custom native code. First install the package with yarn, npm, or expo install.

expo install react-native-ble-manager @matthewwarnes/react-native-ble-manager-plugin

After installing this npm package, add the config plugin to the plugins array of your app.json or app.config.js:

{
  "expo": {
    "plugins": ["@matthewwarnes/react-native-ble-manager-plugin"]
  }
}

Next, rebuild your app as described in the "Adding custom native code" guide.

API

The plugin provides props for extra customization. Every time you change the props or plugins, you'll need to rebuild (and prebuild) the native app. If no extra properties are added, defaults will be used.

• isBackgroundEnabled (boolean): Enable background BLE support on Android. Adds <uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/> to the AndroidManifest.xml. Default false.
• neverForLocation (boolean): Set to true only if you can strongly assert that your app never derives physical location from Bluetooth scan results. The location permission will be still required on older Android devices. Note, that some BLE beacons are filtered from the scan results. Android SDK 31+. Default false. WARNING: This parameter is experimental and BLE might not work. Make sure to test before releasing to production.
• modes (string[]): Adds iOS UIBackgroundModes to the Info.plist. Options are: peripheral, and central. Defaults to undefined.
• bluetoothAlwaysPermission (string | false): Sets the iOS NSBluetoothAlwaysUsageDescription permission message to the Info.plist. Setting false will skip adding the permission. Defaults to Allow $(PRODUCT_NAME) to connect to bluetooth devices.
• bluetoothPeripheralPermission (string | false): Sets the iOS NSBluetoothPeripheralUsageDescription permission message to the Info.plist. Setting false will skip adding the permission. Defaults to Allow $(PRODUCT_NAME) to connect to bluetooth devices.
