[Bluez-users] Cannot send messages to my bluetooth enabled Phone using RFCOMM

[Swathi Mathur80 <swathi_mathur80@yahoo.com>]

Hello,
I am trying to send some data to my bluetooth enabled
Sony Ericsson
handphone T630 from my PC which has the bluez stack
running on it, i am using the RFCOMM.

I get the error message "Cant create socket" and "bad
file descriptor" 

Can someone help me in finding the mistake and in
correcting the below code

------------------------------------------------------------------
#include <stdio.h>
#include <string.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;
   char dest[18] = "00:0A:D9:4C:EB:9A";  // BD of my
sony erricson phone
   
   //allocate a socket
   s =
socket(AF_BLUETOOTH,SOCK_SEQPACKET,BTPROTO_RFCOMM);

   if (s < 0) {
     printf("Cant create socket:\n");
   }


   //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));

  //send a message
  if(status == 0)
  {
   status = write(s,"hello!",6);
  }

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

}
