树莓派连接蓝牙适配器，用C语言与手机通过蓝牙进行通信

[光屁屁打酱油]

#include <stdio.h>
#include <unistd.h>
#include <sys/socket.h>
#include <bluetooth/bluetooth.h>
#include <bluetooth/rfcomm.h>
int main(int argc, char **argv)
{
struct sockaddr_rc addr = { 0 };
int s, status, len=0;
char dest[18 = "00:12:01:31:01:13";
char buf[256;
// allocate a socket
s = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
// set the connection parameters (who to connect to)
addr.rc_family = AF_BLUETOOTH;
addr.rc_channel = (uint8_t) 1;
str2ba( dest, &addr.rc_bdaddr );
// connect to server
status = connect(s, (struct sockaddr *)&addr, sizeof(addr));
if(status){
printf(" failed to connect the device!\n");
return -1;
}
do{
len = read(s, buf, sizeof buf);
if( len>0 ) {
buf[len=0;
printf("%s\n",buf);
write(s, buf, strlen(buf));
}
}while(len>0);
close(s);
return 0;
}
现在树莓派与手机已经连接，但无法读取到手机发送的信息，树莓派上的连接选的是Serial Port
