Bluetooth Low Energy
Short-range low-power wireless protocol.
How it works
BLE devices advertise and connect via GATT services and characteristics, using short bursts to run for months on a coin cell.
Where it is used
Wearables, beacons.
Common pitfall
Connection intervals trade latency for power; mobile OS permissions vary.
