Bluetooth 5.0 – Yes, Version 5 – Primer | #IoT #IoTuesday
Bluetooth 5 has been with us in commercial products for about a year now, so a lot of users are still realizing it’s a thing – either in their device or conceptually something to take advantage of in their IoT design. Mindtribe breaks it down:
Picture yourself going to the store to buy a new phone, speaker, headphones, or a mood ring and you notice it supports Bluetooth 4.2. “Hey!” you think to yourself, “this device only supports old, crummy Bluetooth! Where is that new hot Bluetooth I’ve heard so much about? Isn’t it way better or something?”
After wondering what the difference really is, you end up buying AirPods instead because they say they support Bluetooth 5. This isn’t necessarily the wrong choice – AirPods are pretty fantastic! – but Bluetooth 5 is neither as magical nor as mysterious as you might think. In fact, it’s quite familiar.
First, a quick primer on Bluetooth until now. Major Bluetooth versions can be stratified into 3 categories:
1.X and 2.X are Bluetooth Classic
Bluetooth 3 seems to be its own thing
Bluetooth 4.X and 5.X are the “Low Energy” family – now known as just Bluetooth or Bluetooth 5.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
