Inside Bluetooth: Low Energy

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.

Handles the "raw bits" and frequency hopping across 40 channels to avoid interference. Bluetooth Low Energy (BLE) is essentially the "minimalist"

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") low energy BLE in combination with the ESP32

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).
