For dense areas, mesh applications like BitChat (Jack Dorsey) could bypass the need for a network with p2p bluetooth mesh networks. And works with existing devices, vs something like meshtastic which needs an installed base (afaik).

Does it actually work though? My experience with Meshtastic is it’s so difficult to get a message delivered beyond the nearest hop that it’s almost useless. And Bluetooth has a significantly shorter range than LoRa.

  • The LoRa enthusiasts in my area seem to all have moved to Meshcore, largely because of a quirk in Meshtastic's routing algorithm that doesn't handle nodes with widely varying visibility/power/noisefloor well. They report regularly getting traffic hundreds of miles. There might be a couple mountaintop repeaters in the mesh though.

    For OP's situation I think runners and a store and forward system like Scuttlebutt/Briar/etc might work better. But I'd love to see a couple of thorough case studies on that kind of system, they've been around for many years targeting related scenarios.

    • I’ve tried MeshCore as well and discovered zero nodes. At least what I’ve seen it looks like Meshtastic implemented the same routing fixes MeshCore has.

      I think the issue is more that getting a message many kilometres out using a couple of nodes sitting in non prime locations is just unreliable. The noise is too high. There’s also a limit on how many messages can be sent while using flood routing.
