This is the hardware layer responsible for actually sending and receiving signals over the 2.4 GHz band.

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

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") This is the hardware layer responsible for actually

Bluetooth Low Energy (BLE) is essentially the "minimalist" sibling of classic Bluetooth, designed to stay in a near-zero power state and wake up only for tiny bursts of communication. This architecture allows devices like heart rate monitors and smart tags to run for years on a single coin-cell battery. and the Application .
