Question

我正在尝试使用C编程语言实现蓝牙微微网。我已经阅读了一些论文，并且还经历了一些例子。但我没有得到适当的输出。我使用以下示例设计了服务器和客户端，请检查此link。请查看我正在处理的代码：

任何人都可以建议一个适当的方法来实现它。谢谢。

slave.c

#include <stdio.h>
#include <stdlib.h>

#include <pthread.h>

void receive_ack();
int main()

{
int i;

pthread_t thread1, thread2;

    char dest1[18] = "00:1B:10:00:2A:EC";
    send_message_function(dest1);


}

void send_message_function(char ptr[18])
{
 //printf("MAC::%s",ptr);
struct sockaddr_l2 addr = { 0 };
int s, stat, status, i;

char dest[18], buf[1024];
int bytes_read;

strncpy(dest, ptr, 18);

// allocate a socket
s = socket(AF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_L2CAP);

// set the connection parameters (who to connect to)
addr.l2_family = AF_BLUETOOTH;
addr.l2_psm = htobs(0x1001);
str2ba(dest, &addr.l2_bdaddr);

status = connect(s, (struct sockaddr *) &addr, sizeof(addr));
if (status == 0) {
    stat = write(s, "hello!", 6);

    bytes_read = read(s, buf, sizeof(buf));
    if (bytes_read > 0) {
        printf("received %s\n", buf);
        bzero(buf, 16);
    }

}

if (status < 0)
    perror("uh oh");
close(s);
