Bluetooth Low Energy: Dissecting the Controller Layer—Part 5 of 7

The Bluetooth® Low Energy stack consists of two parts: the host, which is home to the higher layer protocols and profiles, and the controller, where the radio and associated PDU control logic is located. In the fifth part of this series, we dissect the controller into its constituent components and show how the individual blocks work together to ensure a reliable transfer of information.

In Part 6, “Bluetooth Low Energy: All About BLE Security,” we’ll learn how BLE keeps information private.
