That is being consumed, drinking a super strong coffee and connecting my Bluetooth joystick to my TV box and using it as a mouse so I can build beautiful things in the comfort of my couch. They made bluetooth 5 now. If I get the time I will try and find out what the difference is between Bluetooth 5 and Bluetooth 4. I think I will read through the whole Bluetooth article until I sleep. Wikipedia has an article for so many things.
Bluetooth is like WiFi but it is weaker, it is used to connect two devices together. I can send files from my phone to my android box through bluetooth and I can connect input devices like keyboards and joysticks and I can connect output devices like headphones. Blue tooth has become a very versatile connection platform.
