uni-app BroadcastReceiver 广播监听无效，求解

没有开始设备搜索
var BluetoothAdapter = plus.android.importClass("android.bluetooth.BluetoothAdapter");
//获取默认适配器
var bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
bluetoothAdapter.startDiscovery(); //开启搜索设备

碰到同样的问题，不知道兄弟怎么解决的

兄弟，我也想咨询下
设备已经开始搜索了
调用蓝牙广播（以下方法）的时候，就卡在那里没反应了
plus.android.implements('io.dcloud.feature.internal.reflect.BroadcastReceiver', {onReceive: function(context, intent) { }});

最后还是弃用了，因为监听接收消息的时候，发现好像页面卡死了，也不知道有啥好办法，
搜索不到 我这边的原因是因为没有申请到动态权限，代码如下

searchDevices() {  
                let BluetoothAdapter = plus.android.importClass("android.bluetooth.BluetoothAdapter");
