Attribute Protocol

The Attribute Protocol (ATT) is a communication method used in Bluetooth Low Energy (BLE) devices to exchange information, specifically attributes like sensor data or device settings. It helps devices find, read, write, or subscribe to data efficiently. Think of it like a structured conversation where one device asks for specific information or updates, and the other responds accordingly. ATT ensures secure, reliable, and organized data transfer between devices, enabling functionalities like fitness trackers syncing data with smartphones or smart home sensors communicating with controllers.
