Try to behave more realistically in the emulator and send the page timeout after 5.12 seconds, which is the default page timeout. --- emulator/btdev.c | 32 +++++++++++++++++++++++++++++++- 1 file changed, 31 insertions(+), 1 deletion(-) diff --git a/emulator/btdev.c b/emulator/btdev.c index 7b67e9430..6bf0f442b 100644 --- a/emulator/btdev.c +++ b/emulator/btdev.c @@ -1281,6 +1281,27 @@ static void conn_complete(struct btdev *btdev, send_event(btdev, BT_HCI_EVT_CONN_COMPLETE, &cc, sizeof(cc)); } +struct page_timeout_data { + struct btdev *btdev; + uint8_t bdaddr[6]; + unsigned int timeout_id; +}; + +static bool page_timeout(void *user_data) +{ + struct page_timeout_data *pt_data = user_data; + struct btdev *btdev = pt_data->btdev; + const uint8_t *bdaddr = pt_data->bdaddr; + + timeout_remove(pt_data->timeout_id); + pt_data->timeout_id = 0; + + conn_complete(btdev, bdaddr, BT_HCI_ERR_PAGE_TIMEOUT); + + free(pt_data); + return false; +} + static int cmd_create_conn_complete(struct btdev *dev, const void *data, uint8_t len) { @@ -1298,7 +1319,16 @@ static int cmd_create_conn_complete(struct btdev *dev, const void *data, send_event(remote, BT_HCI_EVT_CONN_REQUEST, &cr, sizeof(cr)); } else { - conn_complete(dev, cmd->bdaddr, BT_HCI_ERR_PAGE_TIMEOUT); + struct page_timeout_data *pt_data = + new0(struct page_timeout_data, 1); + + pt_data->btdev = dev; + memcpy(pt_data->bdaddr, cmd->bdaddr, 6); + + /* Send page timeout after 5.12 seconds to emulate real paging */ + pt_data->timeout_id = timeout_add(5120, + page_timeout, + pt_data, NULL); } return 0;
