MeshCore development team splits over trademark dispute and AI-generated code

What is it with mesh projects and having these super draconian trademark enforcers? Meshtastic is the same. One of the main reasons I got interested in MeshCore was reading the Meshtastic trademark rules and just finding them... really really over the top.

I don't know any of the players but I'd bet they're licensed amateur radio operators.

IYKYK. Hams are known for a distinctive personality type that can be at strong odds from other tech people and other comms people. Usually in ways that clash with consequences.

I know a few hams that are chill and they are precious doves. I know quite a few more who I won't even engage with for fear of crossing them and them dedicating their lives to making mine hell. Because I've seen them do it to others.

That's not _just_ the hams, mind you. This behavior is overrepresented in hackerspaces in general. But there's a lot of overlap between those groups. Hasn't changed much in the 40-some-odd years I've been involved there either.

What is IYKYK ? If you know you know?
sweetheart•39m ago
yeah
amatecha•22m ago
Actually the opposite, tons of ppl in the meshtastic community (Discord) berate amateur radio operators. I stopped even discussing the subject because of how much derision I observed or was subjected to. Lots of insults and nasty jokes in passing as soon as the topic even comes up whatsoever. Kinda like your post, actually - offhanded derogatory remarks about an entire group of people solely because of the hobby they're involved in.

All meshtastic code is GPL, the name "meshtastic" is owned by the company that developed it. You can use any of the code, you can't use their name outside their rules. This is absolutely no different than, say, Firefox. The trademark policy is very permissable and you don't even need their permission to use the name on a commercial product.

I think it's totally sensible for the organization to want to have some level of control over what gets their label on it -- the Wi-Fi people wouldn't be very happy about someone slapping their logo all over a bunch of completely incompatible hardware.

Is this client app still closed source? Non-starter for me, also a strong indicator that anything like this was bound to happen, and this will not be the end of it.
queenkjuul•1h ago
Wow, very surprised to learn that it is closed source, and that's probably not changing.

My local mesh was testing out meshcore last week, this definitely kills my interest too

drpfenderson•46m ago
Thankfully there is an open-source client, which has pretty much all the features of the main client as well as some extras.

This reduced my interest to zero in this as well, when I learned it was closed source
marssaxman•16m ago
Shame to hear that: the protocol works well, scaling up to thousands of nodes across hundreds of miles. This is the local mesh where I live: https://cascadiamesh.org/map/

You don't have to use the closed source app; there's an open-source client too, there are Blackberry-style client devices which don't require an app at all, and all the actual firmware is open source (MIT).

amatecha•12m ago
Wow, the coverage is nuts. I should hop on, looks like I've got solid coverage in my area. Been too lazy to properly give it a try but obviously I really should! Thanks for the link!
desireco42•1h ago
I love using AI to develop and I think it is important in modern development, but you definitely have to disclose it because there is a difference between AI and human written code is key.

It is essential to disclose it.

I've played with MeshCore and Meshtastic a bit, and while they are fun, the general hype seems overblown. The "SHTF" types that get involved with this tend to just taint the whole concept for me. I was/am interested in the use cases for building sensor networks, but most of the chatter seems to be around people who just want to send Hello World type texts back and forth, without realizing how poorly a network like this would perform in a real SHTF scenario.

I feel the same way, and both mobile apps are pretty janky, with Meshtastic being extra obnoxious because the UI teams between Android and Apple apparently don't talk to each other- very hard to onboard/answer questions from someone new if you're on a different platform than them.

It was fun and cheap to set up, but I look forward to something with better messaging persistence so you can at least reliably not miss stuff.

I would absolutely encourage everyone reading this to check out Reticulum [1] if you haven't already. I believe the base project might be in need of new maintainers(?) at the moment and the main dev has some very strong takes, but it is a very well-thought out approach to distributed networking at the protocol layer. The existing implementations out there include a desktop app which can function over the internet (IP) or a USB connection to some existing LoRA boards. I recently purchased a LilyGo T-Echo [2] and have had a great experience flashing the open-source firmware and using it connected to a desktop over USB or connected over Bluetooth to the fantastic new companion app Columba [3]. This app seriously makes Reticulum feel like a first class citizen when it comes to parity support for messaging. You can even send files/images (with limitations of course)! And since it works at the network level, you can make your own apps to run over Reticulum as well.

>Would you trust AI generated mesh firmware?

It's ridiculous to me that they're concerned about the trustworthiness of AI-generated code when their code quality is so low. They don't even have automated tests and ignore attempts to add them.[0, 1, 2, 3]

Last I checked, there's little validity checking in the code, so it's possible to broadcast nonsense values (like GPS coordinates outside of Earth's bounds) and the code happily accepts it.

And that's fine if they're just like a scrappy upstart doing their best, but it annoys me to be so high and mighty about their code quality when they don't invest in it.

I really want to like MeshCore but I feel like it's stewardship makes it hard. The main two people I know running it are Scott Powell and Liam Cottle, both of whom are trying to build businesses on closed-source layers on top of the firmware. I don't think there's anything wrong with an open-core business model (I ran such a business myself), but it creates perverse incentives where the core maintainers try to suppress information about the open-source alternatives and push their own closed-source paid products.
