[Bluez-devel] Re: Periodic Inquiry

[Claudio Takahasi <cktakahasi@gmail.com>]

Hi folks,

The inquiry periodic is not working properly. The minimum=20
amount of time specified between consecutive inquiries
is not working as I expect. The device is entering on
inquiry mode every +- 5seconds.

Is there a problem in the code below?

=09inq_param.num_rsp =3D 100;
=09inq_param.length  =3D 4; /* 5.12s */

=09inq_param.max_period =3D 49; /* 62.72s */
=09inq_param.min_period =3D 27;  /* 34.56s */


=09/* General/Unlimited Inquiry Access Code */
=09inq_param.lap[0] =3D 0x33;
=09inq_param.lap[1] =3D 0x8b;
=09inq_param.lap[2] =3D 0x9e;
=09ret =3D hci_send_cmd(sock, OGF_LINK_CTL, OCF_PERIODIC_INQUIRY,=20
=09=09=09PERIODIC_INQUIRY_CP_SIZE, &inq_param);



Regards,
Claudio.
