Adding Bluetooth to your IoT project usually means developing native applications to interact with your devices. However, the new Web Bluetooth API specification allows web browsers to communicate directly with Bluetooth Low Energy devices. While the specification is not finalized yet, we can already experiment with it using Chrome on macOS, Linux, Windows, and Android.
In this article, we will demonstrate how to use bleno – a Node.js library, to implement Bluetooth Low Energy (BLE) peripherals on a balenaOS-powered device and use a web app to communicate with it from a browser.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
