When and Why to Use Bluetooth Low Energy in DIY Projects
Bluetooth used to be something of a battery killer, but with the advent of Bluetooth Low Energy, that has changed. At Adafruit, Colleen explains how to use Bluetooth in DIY projects.
We all know that Bluetooth is a way for two devices to communicate with each other, but it is not the only communication protocol on the unit. Bluetooth Low Energy isn’t just about reducing energy consumption. BLE only connects as needed, so it’s great for periodic updates like reading from a sensor, but not good for streaming anything. More importantly, BLE support is extensive, which means you can easily access it from almost any device.
This is Adafruit’s video of course, so it demonstrates how to use Adafruit’s free Bluefruit app to manage DIY Bluetooth projects. The video talks about several different DIY projects that you would like to use Bluetooth Low Energy for, including a temperature sensor, a car remote, an RGB color controller, and using BLE as a beacon. Even if you don’t want to use the Adafruit app, the video will still be helpful when you use Bluetooth Low Energy instead of regular Bluetooth or Wi-Fi.
