多个BLE设备连接未收到已连接/已断开连接的事件

Question

在从本机获取连接/断开连接事件后，我需要连接/断开多个蓝牙LE设备。

i.e.BluetoothAdapter.STATE_CONNECTED/BluetoothAdapter.STATE_DISCONNECTED。

我能够收到所有的活动 BluetoothAdapter.STATE_CONNECTING,BluetoothAdapter.STATE_CONNECTED，BluetoothAdapter.STATE_DISCONNECTING,BluetoothAdapter.STATE_DISCONNECTED。

如果我正在尝试连接第一台设备。但是当第二个设备尝试连接它时，我只给出了绑定状态而不是连接/断开连接状态。

我已注册下面提到的意图以接收状态更改

<action android:name="android.bluetooth.device.action.BOND_STATE_CHANGED" />
<action android:name="android.bluetooth.device.action.ACL_CONNECTED" />
<action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
<action android:name="android.bluetooth.device.action.CLASS_CHANGED" />
<action   
 android:name="android.bluetooth.adapter.action.CONNECTION_STATE_CHANGED" />
<action android:name="android.bluetooth.adapter.action.STATE_CHANGED" />
<action android:name="android.bluetooth.device.action.ACL_DISCONNECTED" />

请找到我收到的课程
