From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>
This reduces quite a bit the complexity of GATT discovery while
reducing the amount traffic, this is achieved by using breadth-first
like lookup.
Bellow is the traces with using Zephyr peripheral sample which
uses a somewhat small MTU (65 bytes), it probably has even better
results when using bigger MTU.
Luiz Augusto von Dentz (10):
shared/gatt-db: Add gatt_db_get_service
shared/gatt-db: Add gatt_db_service_insert_included
shared/gatt-client: Insert included attribute with handle
shared/gatt-db: Add gatt_db_insert_included
shared/gatt-client: Simplify included discovery
unit/test-gatt: Adjust the PDUs to the new behavior
shared/gatt-db: Add gatt_db_insert_characteristic
shared/gatt-db: Add gatt_db_insert_descriptor
shared/gatt-client: Simplify characteristics discovery
unit/test-gatt: Adjust the PDUs for characteristic discovery
