Backend

Install Arduino from scratch

Copy a working Arduino portable installation that you testet to compile with KniwwelinoLib. Make also sure to not only add all dependencies needed by KniwwelinoLib itself, but also to add all Libraries needed for the Blocks of KniwwelinoBlockly.

Adapt the folder name in the file builds/TEMPLATE/makefile to the path name your Arduino portable is installed.

Alternatively Install our prepacked Arduino

We provide a prepacked Arduino 1.8.5 for Linux on our Wiki. To use it for your server.

cd Backend
wget https://doku.kniwwelino.lu/_media/stuff/arduino-1.8.5_linux.tar.gz
tar -xzf arduino-1.8.5_linux.tar.gz

In case we add new dependencies to the Arduino instance, we recommend to download the tar again. There may be changes in KniwwelinoLib, you can update it by:

cd Backend/arduino-1.8.5/portable/sketchbook/libraries/KniwwelinoLib/
git pull

Configurate your MQTT server

Install mosquitto or any other MQTT broker. Create there a user for the backend to connect to. Please adapt the file config/default.json to your needs.

Init submodules

git submodule update --init --recursive

It seam that the submodule closure that is used by KniwwelinoBlockly is not compatible any more. We use this version https://github.com/google/closure-library/releases/tag/v20160125

Install NodeJS packages

We tested with NodeJS in Version 8.17.0 and 10.15.2

npm install

Run the server

node app.js
