Answer 1

尝试这个:

安装:npm install react-native-bluetooth-status --save
链接此插件:react-native link react-native-bluetooth-status
进口:import { BluetoothStatus } from 'react-native-bluetooth-status';
检查蓝牙开启或关闭代码:

BluetoothStatus.state() 是 return boolean 。如果返回 true 蓝牙是 开启 如果返回 false 蓝牙是 关闭

componentDidMount() 
{
   this.checkInitialBluetoothState();
}

async checkInitialBluetoothState() 
{
const isEnabled = await BluetoothStatus.state();
console.log("check bluetooth on or off", isEnabled);
if(isEnabled == true){
  Alert.alert(
      'Bluethooth',
      'Bluetooth is turn on'
    );
 } else{
    Alert.alert(
      'Bluethooth',
      'Bluetooth is turn off'
    );
  }
}
