When I heard about Web Bluetooth my first thought was "ehi, what if I can make an easy to drag'n'drop library to extend the Tumult Hype functionalities?!?". So, when the API was still in alpha, I started to play with it trying to send commands to a Lego bluetooth controller (SBrick) in order to move a small test robot. The Web Bluetooth implementation status is still a work in progress but mostly you can play with it from Mac OS, Linux (Chrome) and Android (5 with Chromium or 6+ with Chrome).
I decided to created a generic library to manage the Bluetooth device discovery, write, read and cache characteristics:
Bluetooth.js (@MaxZieb Maybe we can add this to the Hype extensions?)
The second part of the project is a specific library to communicate with the SBrick, compatible with the latest version of the protocol:
Then I started to build the UI controls directly in Hype, creating Symbols to manage different kind of interactions (buttons, sliders, joysticks...) and monitors:
With those Symbols I built SBrick Web Controller: a generic Lego SBrick RC controller for a car and a tank, here you can find more infos and online demos: sbrick.360fun.net
