GATT_Notification is a technique to send data from Server(peer device normally) to Client(Host/Master normally) without the Client requesting for updated data value by the method of polling. The server informs the client whenever the data value changes by the way of GATT_Notifications. The typical GATT server is a peripheral device, but this is not mandatory; we could have a peripheral client and a central server, or two central devices communicating with each other.

The peripheral is known as the GATT Server, which holds the ATT lookup data and service and characteristic definitions, and the GATT Client (the phone/tablet), which sends requests to this server.
