Serial port UART通信校验和

我试图解码/理解空调和wifi模块之间的串行（UART）通信协议。我使用Docklight嗅探通信，我有一些关于如何打开交流装置和关闭、改变模式等的结果，但我不知道如何计算CRC。以下是一个例子：

谢谢，

最后两个字节不是消息的CRC。它们不符合CRC的线性特性。

您认为哪里有CRC？你认为为什么会有CRC？我看到在最后两个字节中有很多重复，所以这些可能不是CRC。嗨，马克，我一直在看最后三个字节，它们随着从WIFI到AC单元（CIAT）的每一条发送消息而变化。从末尾算起的第三个数字增加了，但最后两个数字似乎一直不同，你能告诉我在哪里可以重复很多次吗？谢谢好的，我现在知道是整个消息在重复，而不仅仅是最后的两个或三个字节。看起来有三条消息缺少结尾的两个可能的检查字节。它们以

AA 1E AC B2 00 00 64

，

AA 1E AC B2 00 00 65

和

AA 1E AC B2 00 00 66

开头。嗨，马克，如果不是CRC，你能给我解释一下最后三个字节是什么吗。我真的很难理解它。
