Description: Config plugin to auto configure react-native-ble-manager on prebuild
Latest version: 1.1.1

# 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](https://docs.expo.io/workflow/customizing/).
> First install the package with yarn, npm, or [`expo install`](https://docs.expo.io/workflow/expo-cli/#expo-install).

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

After installing this npm package, add the [config plugin](https://docs.expo.io/guides/config-plugins/) to the [`plugins`](https://docs.expo.io/versions/latest/config/app/#plugins) array of your `app.json` or `app.config.js`:

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

Next, rebuild your app as described in the ["Adding custom native code"](https://docs.expo.io/workflow/customizing/) 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`.

          "isBackgroundEnabled": true,
          "modes": ["peripheral", "central"],
          "bluetoothAlwaysPermission": "Allow $(PRODUCT_NAME) to connect to bluetooth devices",
          "bluetoothPeripheralPermission": "Allow $(PRODUCT_NAME) to connect to bluetooth devices"
        }
