What is Bluetooth Low Energy?
Bluetooth Low Energy (BLE) technology, as the name suggests, enables data exchange between devices while consuming very little energy. BLE is an optimized version of classic Bluetooth technology, specifically designed for IoT (Internet of Things) devices.
How does BLE work?
BLE devices primarily operate in two modes: Advertising and Connection. Each BLE device advertises itself to notify nearby devices of its presence. These advertisement messages include basic information about the device and its available services.
Advertising Mode
In advertising mode, a BLE device broadcasts information in short packets. These packets contain the device's identifier and the services it supports. The advertisement messages are kept short and simple to conserve energy.
