详细问题描述
ios的蓝牙写入自从1.9.9更新之后一直报以下错误，我之前在github中提了issue，编号#397
提示写入成功，但是会报错，以及收到的notify有问题，麻烦验证下问题哦，感谢~！
以下日志出自真机调试，ios所有机型，安卓和微信小程序使用正常

求蓝牙打印demo

碰到类似的问题，以前是写入的时候监听事件没响应，1.9.7说事改好了，结果是虽然有响应了，但返回的结果根本不对，大部分时间返回是空值，偶尔返回莫名其妙的字符串

还一个问题，真机调试和越狱包本机运行都能正常写入，虽然返回结果不对，到写入是成功的，但ios上架后安装写入就不成功了，所有步骤都和真机调试一样，返回也一样，但蓝牙设备就是没有接收到数据。一下是log
