ESP8266 TCP传输AT指令顺序


 1 　　　　 ret = ESP8266_Cmd ( "AT+RST", "OK", "ready", 2500 ); //复位
 2         ret = ESP8266_Cmd ( "AT", "OK", NULL, 500 );//测试AT启动
 3         ret = ESP8266_Cmd ( "AT+CWMODE=3", "OK", NULL, 1500 );//选择WIFI应用模式softAP+station
 4         //ret = ESP8266_Cmd ( "AT+CWLAP", "OK", NULL, 2000 );//列出当前可用的接入点
 5         ret = ESP8266_Cmd ( "AT+CWJAP="macUser_ESP8266_ApSsid","macUser_ESP8266_ApPwd"", "OK", NULL, 5000 );
 6         //ret = ESP8266_Cmd ( "AT+CWJAP="BEILIN","BEILIN12345"", "OK", NULL, 5000 );//连接路由
 7         //ret = ESP8266_Cmd ( "AT+CIFSR", "OK", NULL, 2000 );
 8             
 9         ret = ESP8266_Cmd ( "AT+CIPSTART="TCP","192.168.1.126",8081", "OK", NULL, 3000 );//protocol IP port
10         ret = ESP8266_Cmd ("AT+CIPMODE=1","OK",NULL,500);//使能透传模式
11         ESP8266_Cmd ( "AT+CIPSEND", "OK",">", 500 );//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。
