Submodules

We use two submodules, to load them if the repo has already been cloned:

git submodule update --init

Instructions:

Download Balena Image

1. Register in Balena.io
2. Download Image for Raspberry PI 4B and install it to SD Card using Balena Etcher

Flash ESP Code

1. Download ESP8266_Code.cpp and
2. Set Wifi SSID and Password
3. Flash it onto ESP8266 using Arduino IDE
4. Check with predefined weight if values are realistic

Start the backend for debugging

1. Clone the repository to local file
2. Start with Eclipse oder gradle bootRun
3. You need to have MySQL and a MQTT-Server running
4. In the final product: The backend, mqtt server and the database are installed on the raspberry pi using balena cloud
