Inside Bluetooth Low Energy 〈PRO – 2024〉

Defines the "who's who." It determines if a device is a Central (like your phone) or a Peripheral (like a heart rate sensor).

This is the most important part for developers. It defines how data is exchanged using a hierarchy of Services and Characteristics (e.g., a "Battery Service" with a "Level" characteristic). Inside bluetooth low energy

Handles the "raw bits" and frequency hopping across 40 channels to avoid interference. Defines the "who's who

To "put together" a BLE system, you need to understand three major building blocks that work in tandem: the , the Host , and the Application . 1. The Controller (The "Radio") Handles the "raw bits" and frequency hopping across

The "brain" of the radio. It uses a state machine to manage whether the device is Advertising (broadcasting its presence), Scanning (looking for others), or in a Connection state exchanging data. 2. The Host (The "Brain")
