[PATCH v2 08/10] shared/gatt-db: Add gatt_db_insert_descriptor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luiz Augusto von Dentz <luiz.von.dentz@xxxxxxxxx>

This introduces gatt_db_insert_descriptor which is similar to
gatt_db_service_insert_descriptor but doesn't require the caller to
know the service where the attribute should be inserted.
