The goal with this project is to demonstrate a way to add another layer of distance between two people messaging on Signal by using LoRa radios as a transport mechanism. It's also a good demo of how to use our Feathers as 'peripherals' for a desktop computer. We also show how to send messages encrypted with AES (but without including who the sender or receiver are).
This project is intended to be a showcase of one way to do communication without the use of pre-existing infrastructure. It could in theory be easily modified to work as a mesh network, although the protocol would have to be implemented on top of LoRa and is outside the scope of this guide
Materials
You will need 2 of each of these. This project will also work with any other RFM95 board or FeatherWing provided you update the pins.
