wifi_connect_demo.h

#ifndef WIFI_CONNECT_DEMO_H
#define WIFI_CONNECT_DEMO_H

extern int WIFI_STATE;


void WifiConnectDemo(void);


#endif

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();

}
