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

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

Android

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

Add import com.solinor.bluetoothstatus.RNBluetoothManagerPackage; to the imports at the top of the file
Add new RNBluetoothManagerPackage() to the list returned by the getPackages() method

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')

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.
openBluetoothSettings	iOS only Open OS Settings directly to bluetooth settings, recommended to use from Alert dialog, where user decides to change bluetooth state.

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.
