ESP8266 TCP傳輸AT指令順序

 1 　　　　 ret = ESP8266_Cmd ( "AT+RST", "OK", "ready", 2500 ); //復位
        ret = ESP8266_Cmd ( "AT", "OK", NULL, 500 );//測試AT啟動
        ret = ESP8266_Cmd ( "AT+CWMODE=3", "OK", NULL, 1500 );//選擇WIFI應用模式softAP+station
        //ret = ESP8266_Cmd ( "AT+CWLAP", "OK", NULL, 2000 );//列出當前可用的接入點
        ret = ESP8266_Cmd ( "AT+CWJAP=\"macUser_ESP8266_ApSsid\",\"macUser_ESP8266_ApPwd\"", "OK", NULL, 5000 );
        //ret = ESP8266_Cmd ( "AT+CWJAP=\"BEILIN\",\"BEILIN12345\"", "OK", NULL, 5000 );//連接路由
        //ret = ESP8266_Cmd ( "AT+CIFSR", "OK", NULL, 2000 );
            
        ret = ESP8266_Cmd ( "AT+CIPSTART=\"TCP\",\"192.168.1.126\",8081", "OK", NULL, 3000 );//protocol IP port
        ret = ESP8266_Cmd ("AT+CIPMODE=1","OK",NULL,500);//使能透傳模式
        ESP8266_Cmd ( "AT+CIPSEND", "OK",">", 500 );//進入透傳

進如透傳之后，接下來就可以發送數據了，發送+++退出透傳模式。
