Since its invention by Ericsson in 1994, Bluetooth has transformed the way devices communicate wirelessly. Early versions like ব্লুটুথ 1.0 এবং 1.1 introduced basic wireless connectivity, while ব্লুটুথ 2.0 + ইডিআর enabled faster data rates and better audio transmission. সঙ্গে ব্লুটুথ 3.0 + HS, high-speed data became possible, এবং ব্লুটুথ 4.0 marked the arrival of ব্লুটুথ কম শক্তি (ব্লা) for power-sensitive IoT devices.

The milestone came with ব্লুটুথ 5.0, which doubled the speed, extended the range up to 300 মিটার, and increased broadcast capacity eightfold. Later versions such as ব্লুটুথ 5.1 এবং 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.
