CH9126网口配置协议及说明
目录
本文通过wireshark抓包分析了官方配套CH9126搜索上位机软件的底层通信，简单分析了搜索，恢复出厂，配置，获取配置这四个操作。
（1）CH9126简介
CH9126 基于 SNTP 协议的网络授时芯片。主要解决单片机等嵌入式设备时间同步问题。CH9126 具有两种工作模式：①作为 SNTP 客户端，向 SNTP 服务器索取时间，并通过串口输出时间；②作为SNTP 时间服务器，以脉冲和串口数据作为基准时间，对 SNTP 客户端进行网络授时。 芯片内部还有一个独立的数据透传通道，可以实现以太网与串口数据透传。
（2）应用
（3）特点
- 内部自带以太网介质传输层（MAC）和物理层(PHY)。
- 支持 10/100M，全双工/半双工自适应，兼容 802.3 协议。
- 与 802.3x 全双工流控和半双工背压流控完全兼容。
- 支持 MDI/MDIX 线路自动转换。
- 支持 SNTP 服务器和 SNTP 客户端模式。
- 可以通过网络和串口配置芯片参数。
- 串口支持 5、6、7 或者 8 个数据位以及 1 或者 2 个停止位。
- 支持奇、偶、无校验、空白 0、标志 1 等校验方式。
- 波特率支持 300-921600bps。
- 授时精度为 10ms。
- 支持一个独立的数据通道，提供网络转串口的数据透传功能。

（1）通讯方式
CH9126 通过 UDP 广播方式进行网络配置功能。
CH9126 广播本地接收端口：50000，软件上位机广播本地接收端口：60000。
（2）通讯过程
CH9126上位机配置功能主要包括：①搜索，②获取配置，③配置网络参数，④恢复出厂设置。
下面结合通讯过程中的数据包解析设置流程。（通过wireshark抓取到数据包来对上位机软件进行协议解析）
