Since its invention by Ericsson in 1994, Bluetooth has transformed the way devices communicate wirelessly. Early versions like Bluetooth 1.0 y 1.1 introduced basic wireless connectivity, mientras Bluetooth 2.0 + EDR enabled faster data rates and better audio transmission. Con Bluetooth 3.0 + HS, high-speed data became possible, y Bluetooth 4.0 marked the arrival of Bluetooth baja energía (Bolle) for power-sensitive IoT devices.

The milestone came with Bluetooth 5.0, which doubled the speed, extended the range up to 300 medidores, and increased broadcast capacity eightfold. Later versions such as Bluetooth 5.1 y 5.2 added precise location features and enhanced audio support through LE Audio.

Modern Bluetooth radio modules are built on these advancements, supporting both Classic Bluetooth (for audio streaming and voice) and BLE (for low-energy IoT applications). Their evolution ensures broader compatibility, stronger performance, and more diverse use cases across industries.
