Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

The Arduino 101* Bluetooth® LE is based on the Generic Attribute Profile (GATT) architecture. GATT defines a hierarchical data structure that is exposed to connected Bluetooth® LE devices.

For making standalone devices, the Lightblue Bean is a good place to start, as it combines a Bluetooth LE radio with an Arduino for easy programming and control.

One for those interested in developing apps using Bluetooth – the Bluetooth SIG has updated its Smart Starter Kit to help speed mobile development. “The kit consists of a collection of labs that take ...

The Primo comes in the ever-familiar Arduino form factor, but it isn’t meant to be an ‘Internet of Things’ device. Instead, it’s a microcontroller for devices that need to be on the Internet.

It could also allow devices programmed with Arduino "sketches" to interact with each other over Bluetooth 4.0—potentially allowing for the development of swarms of smart devices that can talk ...

The Bluetooth SIG defines three kinds of addresses for messages sent across the mesh: unicast addresses identify a single device element; group addresses represent one or more elements, and can be ...
