What about topical channels if the mesh grows large, to hundreds or thousands of people? E.g. ask support questions in "Local Support" instead of "LongFast"
I do have my private channels named (with the exception of a single secondary channel called LongFast to be able to interact with the "default"/public mesh), but you can only have 7 (or is it 8?) channels per device; that's a hard limit of the firmware/protocol.
From what I've read, I think there's also an upper limit of around a hundred nodes per mesh.
Interesting. I guess it's a self-limiting problem. In effect LongFast would be limited by the number of nodes in your vicinity. Even in a large network, messages propagate to 3 hops so you won't be able to see messages from further away, even if the mesh has thousands more nodes further away.
This mesh doesn't seem to have 100-node limit. It seems to be a device limit where a device can only remember up to 100 nodes and it seems to be removing old ones as it discovers new ones.
Ah, maybe that's the 100 node limit I was thinking of. I'm still relatively new to this myself.
