A peripheral device entering any of the following GAP modes and sending either non-connectable advertising events or scannable undirected advertising events should use adv_fast_interval2 (100ms - 150ms) for adv_fast_period(30s). - Non-Discoverable Mode - Non-Connectable Mode - Limited Discoverable Mode - General Discoverable Mode Signed-off-by: Spoorthi Ravishankar Koppad --- include/net/bluetooth/hci_core.h | 2 ++ net/bluetooth/hci_request.c | 25 +++++++++++++++++-------- 2 files changed, 19 insertions(+), 8 deletions(-) diff --git a/include/net/bluetooth/hci_core.h b/include/net/bluetooth/hci_core.h index 7dfe6ff..a69534d 100644 --- a/include/net/bluetooth/hci_core.h +++ b/include/net/bluetooth/hci_core.h @@ -1512,6 +1512,8 @@ struct hci_mgmt_chan { #define DISCOV_INTERLEAVED_INQUIRY_LEN 0x04 #define DISCOV_BREDR_INQUIRY_LEN 0x08 #define DISCOV_LE_RESTART_DELAY msecs_to_jiffies(200) /* msec */ +#define DISCOV_LE_FAST_ADV_INT_MIN 100 /* msec */ +#define DISCOV_LE_FAST_ADV_INT_MAX 150 /* msec */ void mgmt_fill_version_info(void *ver); int mgmt_new_settings(struct hci_dev *hdev); diff --git a/net/bluetooth/hci_request.c b/net/bluetooth/hci_request.c index d4ecf71..6d8ffcc 100644 --- a/net/bluetooth/hci_request.c +++ b/net/bluetooth/hci_request.c @@ -1199,15 +1199,24 @@ void __hci_req_enable_advertising(struct hci_request *req) return; memset(&cp, 0, sizeof(cp)); - cp.min_interval = cpu_to_le16(hdev->le_adv_min_interval); - cp.max_interval = cpu_to_le16(hdev->le_adv_max_interval); - - if (connectable) + if (connectable) { cp.type = LE_ADV_IND; - else if (get_cur_adv_instance_scan_rsp_len(hdev)) - cp.type = LE_ADV_SCAN_IND; - else - cp.type = LE_ADV_NONCONN_IND; + cp.min_interval = cpu_to_le16(hdev->le_adv_min_interval); + cp.max_interval = cpu_to_le16(hdev->le_adv_max_interval); + } else { + if (get_cur_adv_instance_scan_rsp_len(hdev)) + cp.type = LE_ADV_SCAN_IND; + else + cp.type = LE_ADV_NONCONN_IND; + + if (!hci_dev_test_flag(hdev, HCI_DISCOVERABLE) || + hci_dev_test_flag(hdev, HCI_LIMITED_DISCOVERABLE)) { + cp.min_interval = + cpu_to_le16(DISCOV_LE_FAST_ADV_INT_MIN); + cp.max_interval = + cpu_to_le16(DISCOV_LE_FAST_ADV_INT_MAX); + } + } cp.own_address_type = own_addr_type; cp.channel_map = hdev->le_adv_channel_map; -- 1.9.1
