Frequently Asked Questions
Bluetooth Low Energy (BLE) is a wireless technology designed for short-range communication with minimal power consumption. Introduced in Bluetooth 4.0, it enables IoT devices, wearables, and sensors to communicate for years on a single battery.
BLE is optimized for low power consumption and periodic small data transfers, while Bluetooth Classic is designed for continuous streaming like audio. BLE uses less energy, has lower data rates, and supports many more concurrent connections.
