What Is?
Bluetooth is a short-range wireless communication technology that allows electronic devices to exchange data without the
need for cables.
It operates on the 2.4 GHz radio frequency band and is widely used in devices such as smartphones, laptops, headphones, speakers,
keyboards, and smartwatches.
Originally developed in 1994 by Ericsson, Bluetooth has evolved through multiple versions, each offering improvements in speed, range,
and energy efficiency.
Modern versions like Bluetooth Low Energy (BLE) are designed for devices that need to operate with minimal power consumption, making it
ideal for IoT and wearable technology.
