node-red-contrib-microblue

An easy solution to communicate with your micro:bit by bluetooth

Note: Raspbian/linux are currently the only tested OSes. The other platforms as Windows, Mac OS X, FreeBSD should also work.

Status

This node-red library is in the early stages so things might change and break. Apologies in advance! If the version you use is not stable please try with a previous version.

Prerequisites

Open at least the uart, accelerometer, magnetometer service on your micro:bit. It is not necessary to pair your micro:bit with your bluetooth device.

Linux

• Kernel version 3.6 or above
• sh libbluetooth-dev

Ubuntu/Debian/Raspbian

sudo apt-get install bluetooth bluez libbluetooth-dev libudev-dev

Make sure node is on your path, if it's not, some options:

• symlink nodejs to node: sudo ln -s /usr/bin/nodejs /usr/bin/node
• install Node.js using the NodeSource package

Install

npm install node-red-contrib-microblue
