多个 BLE 连接并显示单个 BLE 连接状态

如何解决多个 BLE 连接并显示单个 BLE 连接状态

通过学习 official Android BLE demo App，我成功实现了多个 BLE 连接和接收数据（多个 BLE 设备使用相同的 BluetoothLeService）。但是，在 DeviceControlActivity 类中，所有设备的连接状态都是“全部连接”或“全部未连接”（见下面的代码）。

如何更改代码以便了解设备的各个连接状态？

例如，设备 1 = 已连接，设备 2 = 未连接。

private final broadcastReceiver mGattUpdateReceiver = new broadcastReceiver() {
    @Override
    public void onReceive(Context context,Intent intent) {
        final String action = intent.getAction();
        if (BluetoothLeService.ACTION_GATT_CONNECTED.equals(action)) {
            mConnected = true;
            updateConnectionState0(R.string.connected);
            updateConnectionState1(R.string.connected);
            invalidateOptionsMenu();
            Log.e(TAG,"ACTION_GATT_CONNECTED ");
        } else if (BluetoothLeService.ACTION_GATT_disCONNECTED.equals(action)) {
            Log.e(TAG,"WHEN IS ACTION GATT disCONNECTED");
            mConnected = false;
            updateConnectionState0(R.string.disconnected);
            updateConnectionState1(R.string.disconnected);
            invalidateOptionsMenu();
            Log.e(TAG,"ACTION_GATT_disCONNECTED ");
            clearUI();
        } else if (BluetoothLeService.ACTION_GATT_SERVICES_disCOVERED.equals(action)) {
            updateGattServices(mBluetoothLeService.getSupportedGattServices(0),0);
            Log.e(TAG,"getSupportedGattServices() is done for device #0");
            try {
                Thread.sleep(700);
            } catch (InterruptedException e) {
                e.printstacktrace();
            }
            updateGattServices(mBluetoothLeService.getSupportedGattServices(1),1);
            Log.e(TAG,"getSupportedGattServices() is done for device #1");
            try {
                Thread.sleep(700);
            } catch (InterruptedException e) {
                e.printstacktrace();
            }
            updateDATA();
        } else if (BluetoothLeService.ACTION_DATA_AVAILABLE.equals(action)) {
            mBluetoothLeService.readCharacteristic(mNotifyCharacteristic,0);
            displayData(intent.getStringExtra(BluetoothLeService.EXTRA_DATA),"=====Get device #0 data ");

            mBluetoothLeService.readCharacteristic(mNotifyCharacteristic1,1);
            displayData(intent.getStringExtra(BluetoothLeService.EXTRA_DATA1),"=====Get device #1 data");
        }
    }
};
