离子 BLE 外设无法被发现

如何解决离子 BLE 外设无法被发现

我的包括：

import { BluetoothLE } from '@ionic-native/bluetooth-le/ngx';

我在安卓设备上激活服务的代码：

this.ble.initialize({request:true,statusReceiver: true,restoreKey: 'appname'}).subscribe((res:any)=>{
  // init as peripheral
  this.ble.initializePeripheral({request:true})
  .subscribe(async (res:any)=>{
    switch(res.status){
      case 'enabled':
        console.log("enabled BLE");
        await this.ble.stopAdvertising(); // stop advertising even before this,the device cannot be seen
        await this.ble.removeAllServices(); // remove all previous services
        await this.AddService(); // add my new service
        const info = await this.ble.getAdapterInfo();
        console.log('INFO: ',JSON.stringify(info)); // get info about device (here it returns that i'm not discoverable)
        await this.StartAdvertising(info.name); // start advertising again => return 'Too many advertisers' and therefore stops
        break;
      default:
        console.log("got other status: ",res.status);
    }
  },(err:any)=>{
    this.status = "Problem";
    console.log("BLE ERROR: ",JSON.stringify(err));
  });
});

其他功能：

async AddService(){
  return this.ble.addService({
    service:'7459',characteristics:[{
      uuid:'7459',permissions: {read: true,write: true },properties : {
        read: true,writeWithoutResponse: true,write: true,notify: true,indicate: true,}
    }]
  }).then(res=>{
    // always succeds -> service is added,but cannot be adverised
    console.log("BLE service added: ",JSON.stringify(res));
  })
  .catch(err=>{
    console.log("BLE service error: ",JSON.stringify(err));
  });
}

async StartAdvertising(name:string='Badge'){
  await this.ble.startAdvertising({
    services:['7459'],service:'7459',name:name
  }).then((res:any)=>{
    console.log("Started advertising: ",JSON.stringify(res));
  }).catch(err=>{
    console.log("BLE advertising error: ",JSON.stringify(err));
    // always returns error
  });
}

如评论中所述，我在尝试将服务宣传为外围设备时遇到了问题。 我一直在遵循此处提供的示例：https://github.com/don/cordova-plugin-bluetoothle 和此处：https://github.com/don/cordova-plugin-ble-peripheral，但无法真正使任何其他设备发现该设备。

我做错了吗？
