两个esp8266之间进行wifi通讯，一个做主站另一个从站，传递int型数据，分别输出主站和从站代码

以下是两个esp8266之间进行wifi通讯，一个做主站另一个从站，传递int型数据的代码。

主站代码：

#include <ESP8266WiFi.h>
#include <WiFiClient.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* host = "192.168.1.2"; // 从站的IP地址
WiFiClient client;

void setup(){
  Serial.begin(115200);
  delay(10);

  //连接WiFi
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

int counter = 0;

void loop(){
  delay(1000);

  //连接从站
  if (!client.connect(host, 80)) {
    Serial.println("connection failed");
    return;
  }

  //发送数据
  counter++;
  String message = String(counter);
  Serial.print("Sending message: ");
  Serial.println(message);
  client.print(message);
  
  //等待数据回复
  while(client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  //断开连接
  client.stop();
}

从站代码：

#include <ESP8266WiFi.h>
#include <WiFiClient.h>
 
const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
WiFiServer server(80);

void setup() {
  Serial.begin(115200);
  delay(10);

  //连接WiFi
  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
  WiFi.begin(ssid, password);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());

  //启动服务器
  server.begin();
}

void loop() {
  WiFiClient client = server.available();
  
  if (client) {
    Serial.println("New client");
    while (client.connected()) {
      if (client.available()) {
        int data = client.parseInt(); //读取数据
        Serial.println(data); //输出数据
        client.print("Data received successfully"); //回复数据
      }
    }
    client.stop();
    Serial.println("Client disconnected");
  }
}
