Android 读取BleGattCharacteristicException特征时异常状态0x06

我正在使用RxAndroidBle库与蓝牙设备通信， 然而最近我遇到了一个奇怪的问题。 当读取一个设备特征时，我收到这样的错误：

BleGattCharacteristicException{macAddress=60:CE:32:BA:9E:70, 
 status=6 (0x06 -> https://android.googlesource.com/platform/external/bluetooth/bluedroid/+/android-5.1.0_r1/stack/include/gatt_api.h), 
 bleGattOperationType=BleGattOperation{description='CHARACTERISTIC_READ'}}

我看到描述中说读取的特征有问题，但我能够在同一台设备上使用一些商业扫描仪或谷歌样本中的普通蓝牙代码读取它。 我检查了特征属性-它已读取属性

我在使用RxAndroidBle的Polidea样本时遇到了相同的错误

在互联网上找不到类似的案例，可能是有人碰到了这样的错误。 其他信息可能是，我连接的设备是一个运行在iPhone上的可编程设备模拟器。 我没有提供任何代码片段，因为我使用的代码与核心示例中的代码相同

谷歌蓝牙示例应用程序中的详细日志，我可以在其中读取该属性

确实存在差异，因为此应用程序在读取值之前设置了通知。应用程序中负责此操作的代码如下所示：

// If a given GATT characteristic is selected, check for supported features.  This sample
    // demonstrates 'Read' and 'Notify' features.  See
    // http://d.android.com/reference/android/bluetooth/BluetoothGatt.html for the complete
    // list of supported characteristic features.
    private final ExpandableListView.OnChildClickListener servicesListClickListner =
            new ExpandableListView.OnChildClickListener() {
                @Override
                public boolean onChildClick(ExpandableListView parent, View v, int groupPosition,
                                            int childPosition, long id) {
                    if (mGattCharacteristics != null) {
                        final BluetoothGattCharacteristic characteristic =
                                mGattCharacteristics.get(groupPosition).get(childPosition);
                        final int charaProp = characteristic.getProperties();
                        if ((charaProp | BluetoothGattCharacteristic.PROPERTY_READ) > 0) {
                            // If there is an active notification on a characteristic, clear
                            // it first so it doesn't update the data field on the user interface.
                            if (mNotifyCharacteristic != null) {
                                mBluetoothLeService.setCharacteristicNotification(
                                        mNotifyCharacteristic, false);
                                mNotifyCharacteristic = null;
                            }
                            mBluetoothLeService.readCharacteristic(characteristic);
                        }
                        if ((charaProp | BluetoothGattCharacteristic.PROPERTY_NOTIFY) > 0) {
                            mNotifyCharacteristic = characteristic;
                            mBluetoothLeService.setCharacteristicNotification(
                                    characteristic, true);
                        }
                        return true;
                    }
                    return false;
                }
    };

至于RxAndroidBle版本，我在1.2.0、1.2.4和1.3.0上进行了测试。 Android版本7.1、6.0.1和5.1

在阅读特性之前，我将尝试实现此通知，因为这是我能看到的唯一区别

哇，我读到这个标题的时候，心里想的是“BattleStarGalaxicaException到底是什么”你用的是什么Android操作系统版本？图书馆的版本是什么？您还可以粘贴用于比较的vanilla Android实现的日志吗？在执行读取之前，我已经用请求的信息注册通知编辑了这个问题。我仍然收到相同的错误。我还从这个正常工作的香草应用程序中删除了整个通知部分，但它没有破坏它，所以我认为这是一个死胡同。
