To me, one of the most interesting parts of Meshtastic is the Websphere MQ roots of MQTT and all the goodness of observability and data analysis that comes from an open message broker.

Light up MQTT-explorer and explore the default topics for a good laugh

I had never heard of this before, then last week I watched a video about it and was hooked. Now I'm seeing it everywhere! Meshtastic and Meshcore are both cool LoRa-based mesh text messaging that operate in an no-license-required band. While this limits your transmit power, it doesn't prohibit encryption - the inverse of most ham radio rules! Some cities have thriving communities of Meshtastic and/or Meshcore. You ca…

So you have the mesh and then what? Do people communicate to distribute prohibited anti-government propaganda or is it a network of people who otherwise be too shy to talk to each other by other means? What is the use case?

I built one and found absolutely no use for it. No one ever, and I mean ever, answers you. It's sort of like ham radio, where you get your technician license and get on a net and discover people are just talking about their antennas. Except it's worse, because all the antenna discussions are happening on Reddit and Discord and not on the network itself.

People are very enamored with what you could theoretically do with it, but they never actually do any of it. It's a hardware fetish, it's all about building boxes with solar panels and seeing how many nodes you can light up on the map. Reminds me of another ham radio thing I never got into, "contesting".

I find it weird that the hop limit is 3 bits, wouldn't that limit the effective range a lot? Unless an intermediate node lies and doesn't decrement and retransmits anyway.

It's flood routed. 3 bits is probably far past what is practical, except in very linear low-node-count networks.

Yeah, I was expecting something fancier than flood routing.

Perhaps a per node hash of known recent routes to avoid flooding every single time and using flooding as a backup.

I would try to select based on the merits of the project and its adoption instead of drama. For me the team behind meshtastic needs some help behind their approach to APIs, the app releases frequently break that contract and they probably just need a little help in that area to improve it. Meshcore sounds compelling to me because it has that fixed vs dynamic target approach which I suspect is more true to the real wo…

the merits of one are largely vibe-coded by one overly enthusiastic guy.

This is the first I've heard of it so I guess its not a real project then.

The use case is off grid communications for whatever you might need.

95% of it is people just doing ping? Pong! In chat.

The cheapest devices are like $10. Order one and have a go.

Is russia densely populated enough to be able to make it work? Around me I'm having trouble getting a connection to any other nodes because there isn't a critical mass of other people running mesh nodes and there's a hill between me and the next city

https://meshmap.net https://www.meshcoretel.ru/en/MOW/map Maybe other maps too... I thing Russia's main problem (not only with mesh) is that you have millions of people living in or near few cities and very few inbetween. And those living "inbetween" typically have no money or time for things like mesh, they are struggling with simplier things.

> And those living "inbetween" typically have no money or time for things like mesh, they are struggling with simplier things.

It's just a personal opinion, but I really think this is not the case in reality.

Those guys in the middle of nowhere are the biggest geeks in LoRa networks. They have more practical scenarios, more to gain and better conditions for great distances.

A friend of mine lives far away from me, barely populated area, a big city in between of us. He struggled to get any network traffic, but now he uses narrow antennas to point to particular repeaters and suddenly the whole metropolis is open to him. We talk with acceptable delivery rates (I'm guessing 70%, which is actually very decent in dense area like mine). He is currently trying to expand his local network. His neighbors are less technical, but they have frequent power failures and need alternative way to reach each other.

On the other hand there is A LOT of client nodes and repeaters in my city. Many struggle to reach even a single repeater - hard to access roofs, high buildings, crowded network with plenty of conflicts. This kills motivation for many.

I recently received my ham (Technician) license. This was mostly a result of the state of conflict between various nations, but something I've long perceived as vital for community and individual resilience and stability in difficult times. Many are using GMRS, as it provides easy access to the entire family for $10 over ten years and requires no test. But as does most UHF/VHF or line-of-sight comms, it relies heavil…

Hats off to you on the ham license! My friend just got hers too!

Re: markdown and hugo, that's an excellent combo. You could easily setup a raspberry pi or $5/mo vps to serve it behind caddy/traefik/nginx and have a working multipage app (mpa) in a weekend.

Or a few minutes with AI haha

Its one of the few places you can be fairly sure you're chatting to people, not bots, who have no agenda to sell you anything.

Of course if it ever becomes popular, that will quickly change. But for now it is like early IRC.

There is no real use case, IMO. I setup a few nodes a couple of months ago. It's mostly no activity, punctuated by some random "can you read me" type messages, and for some unknown reason people who think there is something impressive about them having a node on a commercial flight.

The entire thing would fall over in any kind of scenario where you needed to rely on this janky mesh network as a primary means of communications.

It can be fun/useful for very out of the way things where you have a handful of people out camping, or other off-grid situations. But frankly even in those cases there are far better/established ways to keep in sync if you need to (eg: FRS).

This stuff is mostly a solution looking for a problem.
