[Bluez-users] not able to create socket using any of the protocols ?

[Bluez-users] not able to create socket using any of the protocols ?

[Swathi Mathur80]

Hello,
I tried creating sockets using all the three protocols
but i get the error saying "no such file or directory"

My code is as below 
------------------------------------------------
#include <stdio.h>
#include <errno.h>
#include <fcntl.h>
#include <unistd.h>
#include <stdlib.h>
#include <signal.h>
#include <termios.h>
#include <sys/wait.h>
#include <sys/time.h>
#include <sys/ioctl.h>
#include <sys/socket.h>

#include <bluetooth/bluetooth.h>
#include <bluetooth/hci.h>
#include <bluetooth/hci_lib.h>
#include <bluetooth/sco.h>
#include <bluetooth/rfcomm.h>

#include <unistd.h>
#include <stdarg.h>     /* we need va_list */
#include <errno.h>

int main(int argc, char **argv)
{

	int s;

	if ((s = socket(PF_BLUETOOTH, SOCK_STREAM,
BTPROTO_RFCOMM)) < 0) {
		perror("What is wrong: \n");
	}
return 0;
}

------------------------------------------------------

even if i replace the above with the below 
	if ((s = socket(PF_BLUETOOTH, SOCK_SEQPACKET,
BTPROTO_SCO)) < 0) {
		perror("What is wrong: \n");
	}

------------------------------------------------

Struck with the socket creation. Can somebody identify
the pblm ?

Thanks & Warm Regards,
Swathi.

make sure the correct kernel modules are loaded.
