If the dbs don't really match bt_gatt_client instance will attempt to rediscover the ranges that don't match. --- src/device.c | 21 +++++++++++++++++++++ src/device.h | 1 + src/set.c | 22 ++++++++++++++++++++-- 3 files changed, 42 insertions(+), 2 deletions(-) diff --git a/src/device.c b/src/device.c index 620bbd55ebad..5dc1cd0cdbf2 100644 --- a/src/device.c +++ b/src/device.c @@ -6994,6 +6994,27 @@ struct gatt_db *btd_device_get_gatt_db(struct btd_device *device) return device->db; } +bool btd_device_set_gatt_db(struct btd_device *device, struct gatt_db *db) +{ + struct gatt_db *clone; + + if (!device) + return false; + + clone = gatt_db_clone(db); + if (clone) + return false; + + gatt_db_unregister(device->db, device->db_id); + gatt_db_unref(device->db); + + device->db = clone; + device->db_id = gatt_db_register(device->db, gatt_service_added, + gatt_service_removed, device, NULL); + + return true; +} + struct bt_gatt_client *btd_device_get_gatt_client(struct btd_device *device) { if (!device) diff --git a/src/device.h b/src/device.h index a2b7bb15d200..0794f92d0178 100644 --- a/src/device.h +++ b/src/device.h @@ -66,6 +66,7 @@ struct gatt_primary *btd_device_get_primary(struct btd_device *device, const char *uuid); GSList *btd_device_get_primaries(struct btd_device *device); struct gatt_db *btd_device_get_gatt_db(struct btd_device *device); +bool btd_device_set_gatt_db(struct btd_device *device, struct gatt_db *db); struct bt_gatt_client *btd_device_get_gatt_client(struct btd_device *device); struct bt_gatt_server *btd_device_get_gatt_server(struct btd_device *device); bool btd_device_is_initiator(struct btd_device *device); diff --git a/src/set.c b/src/set.c index bf35ee403b39..4ca2f78c3702 100644 --- a/src/set.c +++ b/src/set.c @@ -28,6 +28,8 @@ #include "src/shared/queue.h" #include "src/shared/ad.h" #include "src/shared/crypto.h" +#include "src/shared/att.h" +#include "src/shared/gatt-db.h" #include "log.h" #include "error.h" @@ -277,8 +279,24 @@ static void foreach_rsi(void *data, void *user_data) bt_crypto_unref(crypto); - if (!memcmp(ad->data, res, sizeof(res))) - device_connect_le(set->device); + if (memcmp(ad->data, res, sizeof(res))) + return; + + /* Attempt to use existing gatt_db from set if device has never been + * connected before. + * + * If dbs don't really match bt_gatt_client will attempt to rediscover + * the ranges that don't match. + */ + if (gatt_db_isempty(btd_device_get_gatt_db(set->device))) { + struct btd_device *device; + + device = queue_get_entries(set->devices)->data; + btd_device_set_gatt_db(set->device, + btd_device_get_gatt_db(device)); + } + + device_connect_le(set->device); } static void foreach_device(struct btd_device *device, void *data)
