生成一段跨设备的TCP 通信的Linux C代码，设备1为客户端，ip是：192.168.52.65，设备2为服务器端，ip是：192.168.52.66

在Linux环境下编写C语言代码来实现在两个设备间的TCP通信，通常会涉及socket编程。下面是一个简单的示例，展示了如何创建一个客户端连接到指定IP地址的服务器：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <unistd.h>

#define PORT 8080
#define SERVER_IP "192.168.52.66"
#define CLIENT_IP "192.168.52.65"

int main() {
    int client_sock;
    struct sockaddr_in server_addr, client_addr;
    socklen_t addr_len = sizeof(server_addr);
    char send_msg[] = "Hello from Client!";
    char receive_msg[1024] = "";

    // 创建客户端套接字
    if ((client_sock = socket(AF_INET, SOCK_STREAM, 0)) == -1) {
        perror("Error creating client socket");
        return 1;
    }

    // 设置客户端地址信息
    memset(&client_addr, 0, sizeof(client_addr));
    client_addr.sin_family = AF_INET;
    client_addr.sin_port = htons(PORT);
    inet_aton(CLIENT_IP, &client_addr.sin_addr);

    // 连接到服务器
    if (connect(client_sock, (struct sockaddr *)&client_addr, addr_len) < 0) {
        perror("Error connecting to server");
        close(client_sock);
        return 1;
    }

    printf("Connected to server at %s:%d\n", SERVER_IP, PORT);

    // 发送消息
    if (send(client_sock, send_msg, strlen(send_msg), 0) <= 0) {
        perror("Error sending message");
        close(client_sock);
        return 1;
    }
    printf("Message sent: %s\n", send_msg);

    // 接收服务器的消息
    ssize_t bytes_received = recv(client_sock, receive_msg, sizeof(receive_msg), 0);
    if (bytes_received > 0) {
        receive_msg[bytes_received] = '\0'; // NULL terminate the string
        printf("Received message: %s\n", receive_msg);
    } else if (bytes_received == 0) {
        printf("Server closed the connection.\n");
    } else {
        perror("Error receiving message");
    }

    // 关闭套接字
    close(client_sock);

    return 0;
}

这个示例演示了基本的客户端功能，实际应用中可能需要处理错误情况，并在服务器响应后断开连接。请确保设备1（运行此程序的计算机）和设备2都已开启了监听该端口的服务。
