你好，能不能同时搜索经典和BLE的蓝牙

作者你好，请问一下我如果只使用readme中提到的"方式二：原始数据收发"的话还需要实现Protocol相关的东西吗？我现在只OnBluetoothTransmitListener的话在收到数据的时候会报错如下:
java.lang.NullPointerException: Attempt to invoke virtual method 'com.stag.bluetooth.protocol.ParseResult com.stag.bluetooth.protocol.Protocol.parse(byte[])' on a null object reference
at com.stag.bluetooth.BluetoothTransfer$2.run(BluetoothTransfer.java:158)
我只想接收原始数据的情况下应该如何处理呢，请作者帮忙谢谢。

Android10中无法扫描到蓝牙设备
Android10好像还没有做适配

连接蓝牙设备会报：E/bt_btif: bta_gattc_cache_load: can't open GATT cache file /data/misc/bluetooth/gatt_cache_ f0:c7:7f:fd:14:52 for reading, error: No such file or directory，连接不上。

我用你的demo就没连接成功过设备

有些设备直接就连接不上

有些设备报错了

搜索到蓝牙设备，点击连接，返回状态false，失败，使用MAC连接，也是连接失败。
