Msc-Summer-Project

My Msc Summer Project

Hardware Used

RFM95 w/ breakout (alternatively this)
GPS (or this)
microSD breakout
DC in + USB-a power regulator (or maybe this)
microSD Card - any card that's 1GiB+ will do.
Arduino Uno
Breadboard
Jumper cables (e.g. a, b, and c)
Battery - Size currently unknown - I'll need to run some tests to see how much power it uses to figure out the right battery size.
Project box - if we can't 3D print one
TPL-5111 - also available from Pimoroni

Run bash ./build setup from the command line at the root of this repository.

Copy settings.custom.cpp.example to settings.custom.cpp and fill in the fields there
- This Bash one-liner can be used to generate a new encryption key in the right formats: head -c16 /dev/urandom | od -tx1 | awk '{ gsub(/^0+\s+/, "", $0); toml=$0; gsub(/\s+/, "", toml); print("settings.toml format: " toml); arduino=toupper($0); gsub(/\s+/, ", 0x", arduino); print("settings.custom.cpp format: 0x" arduino); exit }'
Review settings.h to make sure it matches your setup
Copy the folders in iot/libraries to your Arduino IDE libraries folder

The bash ./build setup should have already installed the necessary dependencies.
Create settings.toml in the root of the repository if it doesn't exist already.
Review server/settings.default.toml and adjust settings.toml to fill in the values for the required fields, not forgetting the encryption key generated when setting up the IoT device.
