这东西真烦人…… 不知道是不是我哪里理解错了？你这个报文转义后是13个字节？正常的808心跳报文应该是没有消息体的，也没有消息包封装项的。
原报文: 7e00020000978290002147029E7D017e
分隔符: 00020000978290002147029E7D01
转义后: 00020000978290002147029E7D (7D01 --> 7D) 长度为 13bytes ??????
0002 消息Id
0000 消息体属性
---> 消息体长度 --> 0
---> 无分包
---> 消息头共12字节
978290002147 terminalId
029E 流水号
7D ??????

@hjki456789 不过默认的消息转义处理在极端情况下好像真是有bug的……改了下，但是我真的不确定……。因为我见过有比较另类的实现厂商。
你可以自己实现 io.github.hylexus.jt808.codec.BytesEncoder 来覆盖默认的逻辑。
