react-native-bluetooth-status

React Native library to query and manage bluetooth state. Querying the bluetooth state works cross-plaform (iOS & Android). In addition, Android can directly enable / disable bluetooth.

Getting started

$ npm install react-native-bluetooth-status --save

Mostly automatic installation

$ react-native link react-native-bluetooth-status

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-bluetooth-status and add RNBluetoothManager.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNBluetoothManager.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainApplication.java

1.1 Add import com.solinor.bluetoothstatus.RNBluetoothManagerPackage; to the imports at the top of the file

1.2 Add new RNBluetoothManagerPackage() to the list returned by the getPackages() method in that file
Note: If you add it to the end of the list it should look something like this:

 @Override
 protected List<ReactPackage> getPackages() {
   return Arrays.<ReactPackage>asList(
       new MainReactPackage(),         // Note the addtional comma needed for the original last item in the list
       new RNBluetoothManagerPackage() // For https://github.com/solinor/react-native-bluetooth-status
   );
 }

2. Append the following lines to android/settings.gradle:

   include ':react-native-bluetooth-status'
   project(':react-native-bluetooth-status').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-bluetooth-status/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-bluetooth-status')
   

Usage

import { BluetoothStatus } from 'react-native-bluetooth-status';

...

  async getBluetoothState() {
    try {
      const isEnabled = await BluetoothStatus.state();
    } catch (error) { console.error(error); }
  }

For further usage examples, see the example project using this library.

API

Method	Description
state	Returns a promise, which will return a boolean value, true if bluetooth is enabled, false if disabled.
enable	Android only Changes bluetooth state. Takes boolean parameter (defaults to true), true to enable, false to disable. Returns a promise, which returns whether the change was successful or not.
disable	Android only Disables bluetooth, same end result as calling enable(false). Returns a promise, which returns whether the change was successful or not.

Thanks

Thanks go to react-native-bluetooth-state library, which was used as the foundation of the iOS implementation. That library hasn't been maintained though, and didn't support Android, or anything other than getting the state.
