👉 Bluetooth computing, often referred to as Bluetooth Low Energy (BLE), is a wireless communication technology designed for short-range, low-power data exchange between devices. Unlike traditional Bluetooth, which was optimized for continuous data transfer and audio streaming, BLE focuses on energy efficiency, making it ideal for battery-powered devices like wearables, sensors, and IoT gadgets. BLE operates in the 2.4 GHz ISM band and uses a simplified protocol stack, allowing devices to connect, discover each other, and exchange small amounts of data with minimal power consumption. This makes it particularly suitable for applications requiring periodic updates or low data rates, such as health monitoring devices, smart home appliances, and beacons. BLE's architecture includes a master-slave model where one device acts as the central hub (master) and others connect as peripheral devices (slaves), facilitating efficient and reliable wireless communication in a wide range of computing applications.
