I hadn’t heard of Meshtastic so I looked it up:
“An open source, off-grid, decentralized, mesh network built to run on affordable, low-power devices”
I would love yo get involved but it only supports Apple (iOS and Mac) and Android (and a web browser).
I was hoping to host a node on a raspberry pi but those run Linux.
Thanks for all the other suggestions though.
Thanks for the info!
