客户端接收WIFI发送的数据

1.首先WIFI模块烧入设置，完成模式设置。

2.在myeclipse中写入TCPServer代码

3.运行TCPServer

#include 
SoftwareSerial WIFISerial(8,9); // RX, TX    //模拟一个软串口
void setup()  {
    Serial.begin(115200);
    pinMode(13, OUTPUT);
    int i=0;
    WIFISerial.begin(115200);
    delay(1000);
    WIFISerial.println("AT");       
    delay(1000);
    WIFISerial.println("AT+RST");          //重启
    delay(2000);
    WIFISerial.println("AT+CWMODE=1");     //设置为station模式
    delay(1000);
    WIFISerial.println("AT+RST");          //重启
    delay(2000);
    WIFISerial.println("AT+CWLAP");          //寻找网络
    delay(2000);
   // WIFISerial.println("AT+CWJAP=\"aaa\",\"ghl44826\""); //连接到想要连接的网络
    WIFISerial.println("AT+CWJAP=\"aaa\",\"ghl44827\"");
    delay(2000);  
    Serial.println("connect");
    delay(2000);  
    WIFISerial.println("AT+CIFSR");        //返回模块的IP地址
    delay(1000);
    WIFISerial.println("AT+CIPMUX=1");     //打开多连接                
    delay(1000);
    //WIFISerial.println("AT+CIPMODE=1");    //透传模式
    //delay(1000);
    WIFISerial.println("AT+CIPSTART=2,\"TCP\",\"10.6.66.199\",20006");
    // 接收数据的计算机地址，连接到 TCP 服务器
    delay(3000);
   
    for(i = 10; i < 100;i++){
      WIFISerial.println("AT+CIPSEND=2,4");
      delay(1000);
      //WIFISerial.println("WLQ XK GCP LK"); 
      WIFISerial.println(i);
      delay(1000);
Serial.println("222");
}
      
    }
   
void loop(){
int i = 0;
    //Serial.println("serial output");   
if (WIFISerial.available()){
     Serial.write(WIFISerial.read());
    //Serial.println("ifwifi serial output");
}
    //Serial.println("only serial output");
    if (Serial.available()){
     WIFISerial.write(Serial.read());
    // Serial.println("if serial output");
}
    for(i = 10; i < 100;i++){
      WIFISerial.println("AT+CIPSEND=2,4");
     delay(1000);
      WIFISerial.println(i);
       delay(1000);
      digitalWrite(13, HIGH);    // turn the LED on (HIGH is the voltage level)
    delay(1000);               // wait for a second
    digitalWrite(13, LOW);     // turn the LED off by making the voltage LOW
    delay(1000);               // wait for a second
    }
}
