Hello I have this code that sends some L2CAP packet to bluetooth device. I want to do the same for BLE device. Could someone please tell what I have to change on that code in order to make it possible for BLE Device?
int main(int argc, char **argv)
{
char *buffer;
l2cap_cmd_hdr *cmd;
struct sockaddr_l2 addr;
int sock, sent, i;
if(argc < 2)
{
fprintf(stderr, "%s <btaddr>\n", argv[0]);
exit(EXIT_FAILURE);
}
if ((sock = socket(PF_BLUETOOTH, SOCK_RAW, BTPROTO_L2CAP)) < 0)
{
perror("socket");
exit(EXIT_FAILURE);
}
memset(&addr, 0, sizeof(addr));
//bind to local address
addr.l2_family = AF_BLUETOOTH;
if (bind(sock, (struct sockaddr *) &addr, sizeof(addr)) < 0)
{
perror("bind");
exit(EXIT_FAILURE);
}
str2ba(argv[1], &addr.l2_bdaddr);
//connect to remote
if (connect(sock, (struct sockaddr *) &addr, sizeof(addr)) < 0)
{
perror("connect");
exit(EXIT_FAILURE);
}
if(!(buffer = (char *) malloc ((int) SIZE + 1)))
{
perror("malloc");
exit(EXIT_FAILURE);
}
memset(buffer, 'A', SIZE);
cmd = (l2cap_cmd_hdr *) buffer;
cmd->code = L2CAP_ECHO_REQ;
cmd->ident = 1;
cmd->len = FAKE_SIZE;
if( (sent=send(sock, buffer, SIZE, 0)) >= 0)
{
printf("L2CAP packet sent (%d)\n", sent);
}
printf("Buffer:\t");
for(i=0; i<sent; i++)
printf("%.2X ", (unsigned char) buffer[i]);
printf("\n");
free(buffer);
close(sock);
return EXIT_SUCCESS;
}
Thank you
