/*
 首次连接流程：app搜索到外设 连接发送指令kGetMNdevVersion获取终端版本。判断是否需要升级。
 升级完成/不需要升级 app发送请求kGetDevNumAndStuCardOrder获取终端序列号，
 ---看UI吧。那就是整个流程
 然后 过程人脸验证会根据 登录返回的 mnqFacePorcess 判断是否开启，

             最后还有一个重要的补充，当我们已经找到了我们感兴趣的characteristic后，他的value并不一定通过1方法或者2方法就可以接收的，就算可以接收，有时候只能用1，有时候只能用2。
             这牵扯到characteristic的一个property
             当为read(0x02)的时候，我们用1方法可以查看，用2就会出错。当为notify(0x10)的时候我们就得用2方法。其他就不说明了，比如write就只能写value······
             
             typedef enum {
             CBCharacteristicPropertyBroadcast = 0x01,
             CBCharacteristicPropertyRead = 0x02,
             CBCharacteristicPropertyWriteWithoutResponse = 0x04,
             CBCharacteristicPropertyWrite = 0x08,
             CBCharacteristicPropertyNotify = 0x10,
             CBCharacteristicPropertyIndicate = 0x20,
             CBCharacteristicPropertyAuthenticatedSignedWrites = 0x40,

             } CBCharacteristicProperties;
             
             所以当我们想查看value的时候，先了解一下这个characteristic的property，看是不是能让我们读的。怎么查看？找BLE外设的设备厂商或者查看外设的说明书。
