TCP Server模式
TCP Server模式配置流程：
一样的借用WiFi扫描连接的基础代码，并在WiFi连接的功能函数里面添加TCP连接功能，WiFi连接在主入口函数中的业务代码
void ICACHE_FLASH_ATTR Wifi_conned(void *arg){ static uint8 count=0; struct ip_info info; //用于获取IP地址的信息 uint8 status; os_timer_disarm(&connect_timer); count++; status=wifi_station_get_connect_status(); if(status==STATION_GOT_IP){ os_printf("Wifi connect success!"); const char remote_ip[4]={192,168,1,103};//用于存放本地IP地址,一定要是自己的电脑真实的本地IP地址 wifi_get_ip_info(STATON_IF,&info); //my_station_init((struct ip_addr *)remote_ip,&info.ip,1025);//Client端初始化主函数 my_server_init(&info.ip,1213);//Server端初始化主函数 return; }else{ if(count>=7){ os_printf("Wifi connect fail！"); return; } } os_timer_arm(&connect_timer,2000,NULL);}user_main.c的所有代码：

找到了一份ESP8266关于TCP通信的源码感觉还不错，怕忘记了就把它放在这里：
