I thought i'd experiment with this Nostr blogging thing and write a short article on the state of Meshtastic and its alternatives.
For years Meshtastic was the only game in town, there wasn't a lot of users but the authors kept plugging away and it has become a thriving ecosystem of open source hardware, software, tools and social scene.
Meshtastic has always been focused on node to node messaging, in particular one of the use cases specifically mentioned was hiking in the wilderness or skiing in the mountains and being able to use these devices off-grid, perhaps even without a phone to communicate with one and other. The project does have a few other features like telemetry, remote admin, packet data etc but the messaging was the focus. Because of this focus, the core functionality needs to be built into the firmware of these low powered devices like ESP32 for example. This restricts what can be done in terms of CPU power and storage, but also makes synchronization between device and phone cumbersome.
Unfortunately, as a messaging platform, Meshtastic still struggles even after all these years. Message delivery and routing are fairly unreliable, 95% of conversations go along the lines of "hello, test, anyone there?". Now I should mention, if you have a very good signal to your peers the reliability can be good, but even then its not a guarantee.
Early on in the Meshtastic journey I stumbled upon a similar project named Reticulum which can utilize the same LoRa based hardware but aims to be a more comprehensive platform for decentralized communications and currently requires a computer or raspberry pi to run the Python backend alongside the LoRa hardware as a radio. Reticulum has historically been a less polished UI experience and a little idiosyncratic in its design which has probably hindered its adoption a little. But the main difference to Meshtastic is Reticulum requires bigger hardware and is less suitable for remote installations, solar powered setups etc. My understanding is once v1.0 has been released (soon) there may be efforts to port the code to native C which may allow hardware nodes to run as repeaters on their own.
More recently a new project has been announced called Meshcore, which is more closely aligned with Meshtastic than Reticulum, Meshcore makes several important improvements to message delivery and routing in an attempt to improve the reliability of the core feature, messaging. Popular Youtube channel Andy Kirby has been central in helping Meshcore gain popularity and I think he may be involved in the commercial aspects of the project. The smartphone apps and website mapping and flasher tools are a bit more polished with Meshcore.
One of the biggest contributors in the space is Liam Cottle who has created mapping websites for Meshtastic & Meshcore, he also built the Meshcore smartphone app and built the fantastic Reticulum MeshChat UI.
With all this new competition Meshtastic appears to be pushing out more frequent updates and whilst they have been introducing more bugs into the software it is nice to see some faster progress.
In my opinion Reticulum is probably the most interesting project with the most potential, but they do need to get the core routing engine running standalone on low powered hardware for the project to expand to more hardware/radio focused users.
That is all. Mesh on!
