ESP32 WIFI配置

注意：在配置WIFI信息的时候，一定要整个的memset一下，否则会出现莫名其妙的错误

	wifi_config_t conf;
	//一定要memset
	memset(conf,0,sizeof(conf));
    memcpy(wifi_config.sta.ssid,"DQ",strlen("DQ"))    	
    memcpy(wifi_config.sta.password,"xiaohehe2015",strlen("xiaohehe2015"));

如果不memset,打印出conf内存中的数据：

00007f0010000000000000000000000000000000000000000e414134038e711400000f0b2fb3f78e600000000000000000057e91180e0b2fb3fecec403f38e7114080e7fb3f0000ffffff7f0000ecec403ff0b2fb3f

memset之后：

0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
