My idea about Meshtastic was to create a mesh network just for sending text between LoRa devices, with guaranteed delivery.
My advisor gave me the following idea: use a camera system (360° camera) that can follow a person (or object), and that can only be accessed through a DNS running on a Raspberry Pi on my home network.
But some project with LoRa or radio frequency interests me a lot.
Good project, although guaranteed delivery is not possible with radio. A good starting place in learning about radio mesh networks is RHMesh, which is built into the RadioHead library.
I have no suggestions for your term paper, but the Forum has a Portuguese Section and we´re in need of reinforcements to help answering questions in our language too
Take a look there every now and then. A bachelor's degree in Computer Science would be helpful.
