GATT (Generic Attribute Profile)
Definition
The protocol framework used by BLE for data exchange. A GATT server exposes data as Services and Characteristics; a GATT client reads or subscribes to them. Fitness trackers, heart rate monitors, and smart locks use GATT. Packet captures of BLE traffic contain GATT read/write/notify operations that reveal the data exchanged.
