Bluetooth vs Bluetooth Low Energy
Bluetooth is a standard protocol for sending information wirelessly between nearby electronic devices. It isn’t the electronics themselves, but rather the rules that are followed by the little gadgets. Bluetooth Low Energy (BLE), is like a subset of rules that allows for very different types of wireless traffic. BLE made it possible for tiny sensors and circuits distributed all over a local area to report in information wirelessly over long periods of time without needing to new batteries or recharging.
