 1 　　　　 ret = ESP8266_Cmd ( "AT+RST", "OK", "ready",  ); //复位

         ret = ESP8266_Cmd ( "AT", "OK", NULL,  );//测试AT启动

         ret = ESP8266_Cmd ( "AT+CWMODE=3", "OK", NULL,  );//选择WIFI应用模式softAP+station

         //ret = ESP8266_Cmd ( "AT+CWLAP", "OK", NULL, 2000 );//列出当前可用的接入点

         ret = ESP8266_Cmd ( "AT+CWJAP=\"macUser_ESP8266_ApSsid\",\"macUser_ESP8266_ApPwd\"", "OK", NULL,  );

         //ret = ESP8266_Cmd ( "AT+CWJAP=\"BEILIN\",\"BEILIN12345\"", "OK", NULL, 5000 );//连接路由

         //ret = ESP8266_Cmd ( "AT+CIFSR", "OK", NULL, 2000 );

         ret = ESP8266_Cmd ( "AT+CIPSTART=\"TCP\",\"192.168.1.126\",8081", "OK", NULL,  );//protocol IP port

         ret = ESP8266_Cmd ("AT+CIPMODE=1","OK",NULL,);//使能透传模式

         ESP8266_Cmd ( "AT+CIPSEND", "OK",">",  );//进入透传

进如透传之后，接下来就可以发送数据了，发送+++退出透传模式。
