GATT Server

A GATT Server is a device or software that offers information or services over Bluetooth using the Generic Attribute Profile (GATT). Think of it as a data provider that stores and shares specific data, like heart rate or battery level, to other devices called GATT Clients. When a client requests, the server responds with the relevant data. This setup is common in wearable devices, sensors, or smart gadgets, enabling seamless short-range communication and data exchange in applications like fitness trackers, health monitors, and smart home devices.
