Bluetooth Low Energy
Bluetooth Low Energy (BLE) is a wireless personal area network technology designed for low-power, short-range communication between devices. It enables efficient data exchange for applications requiring minimal energy consumption, such as IoT sensors, wearables, and beacons. BLE operates in the 2.4 GHz ISM band and is distinct from classic Bluetooth, focusing on intermittent data transmission rather than continuous streaming.
Developers should learn BLE for building IoT devices, fitness trackers, smart home gadgets, and location-based services where battery life is critical. It's essential for applications like health monitoring, asset tracking, and proximity marketing, as it allows devices to run for months or years on small batteries. Use BLE when you need to connect low-power peripherals to smartphones or gateways without draining power quickly.
