[Bluez-users] Definition of hci_conn_info_req

Hi

Another basic question.The statement below is a request to establish
connection with a remote device,right?

struct hci_conn_info_req *cr;
cr = malloc(sizeof(*cr) + sizeof(struct hci_conn_info));

Now,is &cr->bdaddr supposed to be the remote device bluetooth address?

When I convert this value to string and output it, it doesn't give me the
correct value for the remote bluetooth device. It returns 08:04:9A:AC:00:00.
Doesn't make sense to me.

Regards
 Arpit

no, it is not.

Depends on how you convert the address. Use ba2str().

Hi Marcel

What does hci_conn_info_req do then?Any documentation anywhere?I'm kinda
lost with all the Bluez code.

> Depends on how you convert the address. Use ba2str().

Yes I'm using ba2str to convert.My question is, should &cr->bdaddr contain
the address of the remote bluetooth device?

    char add[18];
    struct hci_conn_info_req *cr;
    cr = malloc(sizeof(*cr) + sizeof(struct hci_conn_info));
    bacpy( &cr->bdaddr, &bdaddr );
    ba2str( &bdaddr, add);
    printf("Bluetooth address-remote device: %s \n", add);
    cr->type = ACL_LINK;

Everytime I run the executable C, I get a different value for &cr->bdaddr.

Arpit

you can get information about the current established connections.

Where does bdaddr come from?
