移植代码从机智云“stm32f103c8x”平台生成的代码中复制Gizwits、Hal、Utils文件夹到当前目录：

https://www.stmcu.com.cn/upload/20200103/42.png
在工程中添加如下的目录结构：

https://www.stmcu.com.cn/upload/20200103/43.png
修改代码首先在gizwits_product.h / hal_key.h 中将原来F103C8平台的头文件 #include <stm32f1xx.h>替换为G071RB平台的 #include <stm32g0xx.h>然后修改如下代码：修改gizwits_product.c代码：

通过配网进行绑定

请问有详细点的操作步骤吗，之前没有接触过WiFi模块是不是需要像蓝牙一样进行一些配置然后才可以进行连接谢谢
