How the peripheral data is structured in Bluetooth connection?

The peripheral data is represented in the form of services and characteristics. Each peripheral device may offer more than one service. Each service is distinguished from the other by the use of UUID(Unique Numeric ID). Services is a collection of data and associated information for accomplishing a function or feature of a device. Characteristics provide further information about peripheral device and may contain properties, values and descriptors. Like service, characteristics also contain UUID which helps differentiate one from the other.
