当串口数据接收分段时,需要对接收到的数据进行重组,将属于同一数据帧(或数据包)的分段数据组装起来,以恢复出完整的数据帧。

如何重组可以指导一下吗，第一次用。不是很懂原理。只是每次读取的时候偶尔会分段返回，一次不返回完全，要等下一次卡片贴上去的时候才返回，我的send间隔时间500ms

你的工程大致工作流程是通过Uart串口连接NFC模块，实现NFC设备间数据传输的对吗
你可以将NFC模块连接到电脑，打开串口调试助手，测试是否存在数据读取不全的问题

的确是模拟nfc功能，设备厂商提供了命令码。您说的意思是还是我的模块有可能有问题是吧，我下载了一些其他的测试软件，在显示16进制的时候没有出现卡号分割的问题。

你需要参考这部分实现处理一下数据读取，粘包处理
