Re: [Bluez-devel] dd - device descriptor HELP :)

[Flávio <flavio.henriques@gmail.com>]

Hi Marcel, sorry if i wasn=B4t specific!
Ok, this is the important part of my program:
i give 2 arguments in the line command (example: program hci0 bdaddr)
***************************************************************************=
*****************************
       int ptype =3D HCI_DM1 | HCI_DM3 | HCI_DM5 | HCI_DH1 | HCI_DH3 |
HCI_DH5; protocol
       uint8_t role=3D 0x01;

=09str2ba(argv[2], &bdaddr);
=09dev_id =3D atoi ( argv[1] + 3 );     // hciX (X=3Ddev_id)
=09printf("dev_id=3D%i\n",dev_id);
=09dd =3D hci_open_dev(dev_id);     // device descriptor (dd)
=09if (dd < 0) {
=09=09perror("HCI device open failed");
=09=09exit(1);
=09}
=09printf("dd=3D%i\n",dd);
=09if (hci_create_connection(dd, &bdaddr, htobs(ptype),0, role, &handle,
25000) < 0)
=09=09perror("");
***************************************************************************=
*****************************

I have 2 dongles in my computer (hci0 and hci1) when i try to connect
with the 2 at the "same time" to a third bluetooth test (isn=B4t in my
computer), give me an error of connection!
I tryied debugging and think that the problem is because the device
discriptor that hci_open_device returns is the same even the dev_id is
diferente!
In my test the dev_id was 0 and 1, and the function in cause return
the same device descriptor!
The device descriptor shouldn=B4t be different(for different dev_id)?
Note that when i connect with only one (example hci0), the program
works well,the problem is when i try the second connection(example
hci1). Both (hci0 and hci1)is in master mode!
Why isn=B4t work?

One more thing, in the hci_create_connection the "role" argument is
oX01, what is purpuse and the values that sould have?

The last argument of hci_create_connection is diferent depending of
the situations how can i know the values that sould be used, what is
purpuse?

I hope that this time i was more specific!=20
Thanks for the time!
Regards Fl=E1vio
