react-native-bluetooth-status

React Native library to query and manage bluetooth state. Querying the bluetooth state works cross-plaform (iOS & Android). In addition, iOS can open the bluetooth settings and 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 LibrariesAdd Files to [your project's name]
  2. Go to node_modulesreact-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 PhasesLink 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
   );
 }
  1. 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')
    
  2. 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.

You can’t perform that action at this time.
