10/12/26 - present
My friend and I had set out to create a P2P decentralized messaging service using cheap ESP32 LoRA boards, so that we could create a messaging service that would utilize WiFi and allow for an interface and a network that would make it easy to view the messages being transmitted across the network.
We were able to successfully create said messaging service, and were able to send messages between both LoRA boards, and were able to build a GNURadio flowgraph to intercept the messages and decode them.
