一个esp8266开发板向两个esp8266开发板发送数据的代码怎么写

要实现一个ESP8266开发板向两个ESP8266开发板发送数据，你可以使用ESP8266的WiFi功能和网络通信库来实现。以下是一个示例代码，演示了如何发送数据给两个ESP8266开发板：

#include <ESP8266WiFi.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

const IPAddress receiver1IP(192, 168, 1, 100); // 第一个接收器的IP地址
const IPAddress receiver2IP(192, 168, 1, 101); // 第二个接收器的IP地址
const int receiverPort = 1234; // 接收器的端口号

WiFiClient client;

void setup() {
  Serial.begin(115200);
  
  WiFi.begin(ssid, password);
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  
  Serial.println("Connected to WiFi");
}

void loop() {
  if (!client.connected()) {
    if (client.connect(receiver1IP, receiverPort)) {
      client.println("Hello from sender to receiver 1");
      client.stop();
    }
    else {
      Serial.println("Connection to receiver 1 failed");
    }
    
    if (client.connect(receiver2IP, receiverPort)) {
      client.println("Hello from sender to receiver 2");
      client.stop();
    }
    else {
      Serial.println("Connection to receiver 2 failed");
    }
    
    delay(5000); // 每隔5秒发送一次数据
  }
}

请确保将代码中的`your_SSID`和`your_PASSWORD`替换为你的WiFi网络的名称和密码。此外，还需要将`receiver1IP`和`receiver2IP`替换为两个接收器的实际IP地址。
