This result changed after I added some lines in function
hci_conn_check_pending() in net/bluetooth/hci_conn.c in kernel 2.6.39,
following change make ACL connection and it lets succeed the command:
# hcitool info 00:1A:7D:60:4A:AA

------------------- changes in hci_conn.c -----------from here
void hci_conn_check_pending(struct hci_dev *hdev)
{
struct hci_conn *conn;
BT_DBG("hdev %s", hdev->name);
hci_dev_lock(hdev);
conn = hci_conn_hash_lookup_state(hdev, ACL_LINK, BT_CONNECT2);
if (conn)
hci_acl_connect(conn);
+ else {
+ conn = hci_conn_hash_lookup_state(hdev, ACL_LINK, BT_CONFIG);
+ if (conn) {
+ BT_DBG("I couldn't find BT_CONNECT2 but
BT_CONFIG: address %s", batostr( &(hdev->bdaddr) ) );
+ hci_acl_connect(conn);
+ }
+ }
hci_dev_unlock(hdev);
}
------------------- changes in hci_conn.c -----------to here
>From enum definition in bluetooth.h:
BT_CONNECT2 = 6
and
BT_CONFIG = 7
Why the status was BT_CONFIG and was not BT_CONNECT2?
Anyway, it doesn't help to create connection to the headset device:
# hcitool cc 00:1A:7D:60:4A:AA
hcidump shows:
< HCI Command: Create Connection (0x01|0x0005) plen 13
bdaddr 00:1A:7D:60:4A:AA ptype 0xcc18 rswitch 0x01 clkoffset 0x0000
Packet type: DM1 DM3 DM5 DH1 DH3 DH5
> HCI Event: Command Status (0x0f) plen 4
Create Connection (0x01|0x0005) status 0x0b ncmd 1
Error: ACL Connection Already Exists
So I'm not sure the change is right or not.
Any suggestions?
