NeptuneWiFi连接——STA模式

篇首语：本文由编程笔记#小编为大家整理，主要介绍了Neptune WiFi连接——STA模式相关的知识，希望对你有一定的参考价值。

WiFi连接的代码示例是 wm_sta_demo.c

1.测试步骤
手机设置热点&＃xff0c;或者将路由器的热点名称改成 hihope

mm改成12345678

在UserMain函数最后面调用w800_sta_demo函数

void UserMain(void)
printf("\\n user task \\n");
#if DEMO_CONSOLE
CreateDemoTask();
#endif
#if defined(LOSCFG_KERNEL_TEST_FULL) || defined(LOSCFG_KERNEL_TEST)
LosAppInit();
#else
if (DeviceManagerStart())
printf("[%s] No drivers need load by hdf manager!",__func__);

#endif
w800_sta_demo();


编译烧录后查看打印信息&＃xff1a;

说明WiFi连接成功
