Fantastic news from Gordon Williams of Espruino fame. We finally have proper Web Bluetooth support coming on Chrome on Windows.
"Web Bluetooth for Windows now works with Espruino on googlechrome Canary! You can now do embedded hardware development straight from your browser on Windows, MacOS, Chromebook, Linux and Android!"
I highly recommend Gordon's Pixl.js project which was inspired by the NodeConf EU badge that he designed with us.
