From e73439d8c0e4c522c843b8bb98c0eb5700da6b05 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 26 Jul 2010 10:06:00 -0400 Subject: Bluetooth: Defer SCO setup if mode change is pending Certain headsets such as the Motorola H350 will reject SCO and eSCO connection requests while the ACL is transitioning from sniff mode to active mode. Add synchronization so that SCO and eSCO connection requests will wait until the ACL has fully transitioned to active mode. < HCI Command: Exit Sniff Mode (0x02|0x0004) plen 2 handle 12 > HCI Event: Command Status (0x0f) plen 4 Exit Sniff Mode (0x02|0x0004) status 0x00 ncmd 1 < HCI Command: Setup Synchronous Connection (0x01|0x0028) plen 17 handle 12 voice setting 0x0040 > HCI Event: Command Status (0x0f) plen 4 Setup Synchronous Connection (0x01|0x0028) status 0x00 ncmd 1 > HCI Event: Number of Completed Packets (0x13) plen 5 handle 12 packets 1 > HCI Event: Mode Change (0x14) plen 6 status 0x00 handle 12 mode 0x00 interval 0 Mode: Active > HCI Event: Synchronous Connect Complete (0x2c) plen 17 status 0x10 handle 14 bdaddr 00:1A:0E:50:28:A4 type SCO Error: Connection Accept Timeout Exceeded Signed-off-by: Ron Shaffer Signed-off-by: Marcel Holtmann --- include/net/bluetooth/hci_core.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/net') diff --git a/include/net/bluetooth/hci_core.h b/include/net/bluetooth/hci_core.h index 350b3e6964bd..8b28962e737e 100644 --- a/include/net/bluetooth/hci_core.h +++ b/include/net/bluetooth/hci_core.h @@ -256,6 +256,7 @@ enum { HCI_CONN_ENCRYPT_PEND, HCI_CONN_RSWITCH_PEND, HCI_CONN_MODE_CHANGE_PEND, + HCI_CONN_SCO_SETUP_PEND, }; static inline void hci_conn_hash_init(struct hci_dev *hdev) @@ -336,6 +337,7 @@ void hci_acl_connect(struct hci_conn *conn); void hci_acl_disconn(struct hci_conn *conn, __u8 reason); void hci_add_sco(struct hci_conn *conn, __u16 handle); void hci_setup_sync(struct hci_conn *conn, __u16 handle); +void hci_sco_setup(struct hci_conn *conn, __u8 status); struct hci_conn *hci_conn_add(struct hci_dev *hdev, int type, bdaddr_t *dst); int hci_conn_del(struct hci_conn *conn); -- cgit v1.2.3
