Zigbee是一种无线通信协议,可以用于传输各种数据。下面是一个示例程序,用于在Zigbee网络中传输温度、PH值和水浊度数据:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <unistd.h>
#include <errno.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <netdb.h>
#include <netinet/in.h>
#include <fcntl.h>
#include <termios.h>
#define PORT 8080
#define BAUDRATE B115200
#define MODEMDEVICE "/dev/ttyS0"
int main()
{
int sockfd, newsockfd, opt = 1;
struct sockaddr_in servaddr, cliaddr;
char buffer[1024];
int len, n;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd == -1) {
perror("socket creation failed");
exit(EXIT_FAILURE);
}
memset(&servaddr, 0, sizeof(servaddr));
servaddr.sin_family = AF_INET;
servaddr.sin_addr.s_addr = INADDR_ANY;
servaddr.sin_port = htons(PORT);
if (bind(sockfd, (struct sockaddr*)&servaddr, sizeof(servaddr)) < 0) {
perror("bind failed");
exit(EXIT_FAILURE);
}
if (listen(sockfd, 1) < 0) {
perror("listen");
exit(EXIT_FAILURE);
}
printf("server listening on port %d\n", PORT);
len = sizeof(cliaddr);
newsockfd = accept(sockfd, (struct sockaddr*)&cliaddr, &len);
if (newsockfd < 0) {
perror("accept");
exit(EXIT_FAILURE);
}
printf("client connected from %s:%d\n", inet_ntoa(cliaddr.sin_addr), ntohs(cliaddr.sin_port));
// configure serial port
int fd = open(MODEMDEVICE, O_RDWR | O_NOCTTY | O_SYNC);
if (fd < 0) {
perror(MODEMDEVICE);
exit(EXIT_FAILURE);
}
struct termios options;
tcgetattr(fd, &options);
cfsetispeed(&options, BAUDRATE);
cfsetospeed(&options, BAUDRATE);
options.c_cflag |= (CLOCAL | CREAD);
options.c_cflag &= ~CSIZE;
options.c_cflag |= CS8;
options.c_cflag &= ~PARENB;
options.c_cflag &= ~CSTOPB;
tcsetattr(fd, TCSANOW, &options);
printf("serial port %s configured with baud rate %d\n", MODEMDEVICE, BAUDRATE);
while (1) {
// read data from serial port
n = read(fd, buffer, sizeof(buffer));
if (n < 0) {
perror("read");
exit(EXIT_FAILURE);
}
// send data to client over Zigbee
n = send(newsockfd, buffer, sizeof(buffer), 0);
if (n < 0) {
perror("send");
exit(EXIT_FAILURE);
}
printf("data sent to client: %s\n", buffer);
}
close(newsockfd);
close(sockfd);
close(fd);
return 0;
}
```
这个例子中,我们使用了一个TCP服务器来接收来自Zigbee网络的数据,并将其转发到串行端口。当串行端口上有数据时,程序会将其发送到Zigbee网络,并将其打印到控制台。请注意,这只是一个示例程序,您需要根据您的需要进行修改和调整。
