Raspberry Pi

4/9/2016 (this stuff changes rapidly) Following instructions from https://www.raspberrypi.org/downloads/ I made a Raspbian image for the SD card using this file: 2016-03-18-raspbian-jessie-lite.zip

Once the rPi was up and running, I made sure it connected to Wifi: https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md

Following instructions similar to https://blog.wia.io/installing-node-js-on-a-raspberry-pi-3 I installed nodejs by downloading the latest node from nodejs.org:

wget https://nodejs.org/dist/latest-v5.x/node-v5.10.1-linux-armv6l.tar.gz
tar -xvf node-v5.10.1-linux-armv6l.tar.gz

and copying the extracted contents into /usr/local/

cd node-v5.10.1-linux-armv6l
sudo cp -R * /usr/local/

Install some dependencies for Noble:

https://github.com/sandeepmistry/noble/wiki/Getting-started

sudo apt-get install bluetooth bluez libbluetooth-dev libudev

With nodejs installed

OsX, Linux, Windows:

npm install -g brewometer

On Raspberry pi:

sudo npm install --unsafe-perm brewometer

On the Raspberry pi, installing brewometer as a user with sudo requires the --unsafe-perm flag, you can also install as root by creating root password:

sudo passwd

then log in as root, and you can then use

npm install -g brewometer
