Bluetooth LE
Bluetooth LE is like a secret language that two devices use to talk to each other when they are really close by, like when you hold your toy phone up to your ear and pretend to call your friend who is sitting right next to you.
But instead of talking with words, Bluetooth LE talks using radio waves. That's why you don't need any wires to connect two devices that use Bluetooth LE.
But why do we need Bluetooth LE? Well, it's great for making things like smartwatches, fitness trackers, and other devices that we can wear on our bodies. These devices need to be small and lightweight, so they can't use a lot of power from a battery. Bluetooth LE uses very little power, so these devices can talk to your phone all day without draining the battery.
And that's it! Bluetooth LE is just a some radio waves that help different devices talk to each other when they're close by, and it's very helpful for things we wear on our bodies.
