react-native-bluetooth-status

React Native library to monitor and manage bluetooth state. Monitoring the bluetooth state works cross-plaform (iOS & Android). In addition, Android can directly enable / disable bluetooth. V2 introduced new Hooks API!

Installation

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

On RN 0.60+ with autolinking run pod install in your ios/ folder.

RN < 0.60

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

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')

Hooks API:

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

...

const [btStatus, isPending, setBluetooth] = useBluetoothStatus();
return (
  {!isPending && <Text>{btStatus ? 'On' : 'Off'}</Text>}
  <Button title="Toggle BT" onPress={() => setBluetooth(!btStatus)} />
)

| Variable | Description | | :--------------- | :------------------------------------------------------------------------------------------------------------------------------ | | btStatus | Current Bluetooth status. Starts undefined, but updated asynchronously right away. Updated automatically if status changes. | | isPending | Starts at true and after getting first Bluetooth status, is set to false. Helps to know when btStatus is not undefined anymore. | | setBluetooth | Android Only Enables / disabled bluetooth. Takes boolean parameter (defaults to true) to select the operation. |

Imperative API

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

...

async getBluetoothState() {
  const isEnabled = await BluetoothStatus.state();
}

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

| Method | Description | | :----------------- | :-------------------------------------------------------------------------------------------------------------------------- | | state | Returns a promise, which will return a boolean value, true if bluetooth is enabled, false if disabled. | | addListener | Takes function parameter, which will be run when BT status changes, with the new BT on/off status (true / false). | | removeListener | Removes listener. | | enable | Android only Changes bluetooth state. Takes boolean parameter (defaults to true), true to enable, false to disable. | | disable | Android only Disables bluetooth, same end result as calling enable(false). |
