Sending data through L2CAP over bluetooth

[k.mohan]

Hi all,

I am trying to send data using L2CAP layer. For that i have
written the following program:

int hcisend(size_t datlen)
{
int ctl,nb,i;
unsigned char *tem;
unsigned short psm;


struct sockaddr_l2 addr;

bdaddr_t bdaddr;

str2ba("00:0B:0D:33A:F9",&bdaddr);



if ((ctl = socket(PF_BLUETOOTH, SOCK_SEQPACKET, BTPROTO_L2CAP)) < 0)
{
printf("\nCan't open L2CAP socket.\n");
exit(1);
}
else
printf("\nL2CAP socket opened successfully.%d\n",ctl);


memset(&addr, 0, sizeof(addr));
psm=0x1;
addr.l2_family=PF_BLUETOOTH;
addr.l2_psm=htobs(psm);
bacpy(&addr.l2_bdaddr,&bdaddr);

printf("\nPacket:\n");


for(i=0;i<datlen+4;i++)
printf(" %x ",packet[i]);
printf("\n");

while (0 > connect(ctl, (struct sockaddr *)&addr, sizeof(addr)))

if (errno != EAGAIN)
{
perror("connect");
return -1;
}

if ((nb=send(ctl,&packet[0],(datlen+4),MSG_DONTWAIT))< 0)
perror("\nCan't send data.\n");
else
{
printf("\nNo. of bytes sent=%d\n",nb);
return 0;
}

close(ctl);

}

On the other side i am just dumping the data using hcidump. I am
getting the following result:

HCIDump - HCI packet analyzer ver 1.16

On the sending side, I am getting "connection refused". Anybody
please give me the solution to overcome this problem. I am in ver urgent.
