复制代码

wifi_connect_demo.h

1. #ifndef WIFI_CONNECT_DEMO_H
   
2. #define WIFI_CONNECT_DEMO_H
   
3. 
   
4. extern int WIFI_STATE;
   
5. 
   
6. 
   
7. void WifiConnectDemo(void);
   
8. 
   
9. 
   
10. #endif

复制代码

然后在项目中使用
在BUILD.gn的features数组添加"//domains/iot/link/wifi:wifi_demo"
然后在hello_word.c中使用
#include "wifi_connect_demo.h"
void HelloWorld(void){
WifiConnectDemo();
}
