Zurzeit gibt es, nach meinem heutigen Kenntnisstand, drei wichtige #Meshnetzwerke. Zunächst das allseits bekannte #Meshtastic, dann #Reticulum und auch #MeshCore.

Während sich Reticulum hauptsächlich als #Cryptography basierten Netzwerk-Stack sieht, das auch (!) LoRa kann, so tritt MeshCore eher in die Fußstapfen von Meshtastic, vermeidet dabei aber die Konzeptfehler, die gleich zu Anfang bei Meshtastic entstanden sind. Damals konnte ja noch kein Entwickler ahnen, welchen Zulauf und welche Größe MT erreichen wird.

Bei MC wird deshalb von vornherein auf viele Dinge verzichtet, die zwar "nett" sind, aber das Netz belasten und nicht wirklich nötig sind.

Dazu zählt, dass nicht jeder Node auch gleich ein "Repeater" ist, ständig Telemetriedaten über das Mesh geschickt werden und vieles mehr.

Es werden also wesentlich (!) weniger Daten durch das Netz "gequetscht". MeshCore ist jetzt seit rund vier Monaten online, aber ein absoluter "Senkrechtstarter". In London sind bereits mehr als 100 Nodes online und insgesamt schon mehr als 1.100 Nodes.

Aktuelle Infos und die Möglichkeit zum Austausch zu allen dreien findest du hier:

Spain power cuts - fortunately we are somewhat prepared with solar electricity, cash supplies, 15000 litres of water storage, fuel in car & about a months worth of dehydrated meals 😆. In case of a zombie apocalypse 🧟‍♂️or natural disaster we also have walkie talkies, LoRa radios & I have been developing off-grid networks (experimenting with #Meshtastic, #Meshcore & #Reticulum) 🤣.

Bit of a wake up call though - prepare for these events no matter how far fetched they seem. They can and do happen.

Cleaning up the wiring and checking antenna SWR with a NanoVNA.

Was curious if these cheap antennas were similar to their name brand look alikes. And no, no they are not comparable lol. Stick to the name brand I guess for this style of antennas, the cheaper ones are not worth it this time.

Continued thread

Talking about Seeed and #meshcore solar nodes, here is mine.

It uses a simple 6W solar panel designed for cameras, a xiao-esp32-S3, a 820mAh bat. The antenna and the mcu both come from Seeed ;)

The battery was initially a 2000mAh and I had to use a smaller one because of the small enclosure ... the node is still up after 21 days !

I've been using a custom repeater firmware where the mcu spends most of its time in light sleep (without solar panel the chip can stay up 4 days)

meshcore-cli, command line interface for #meshcore is taking shape after a major refactoring of the associated python library.

It now features an IM prompt (Interactive Mode/Instant Message) made with prompt-toolkit and has a cleaner json output for better integration in shell scripts.

Are there any projects to run a single radio to serve as a repeater/router for both #meshtastic and #meshcore ? (Courtesy tag to #reticulum )

Cool to see healthy competition between projects and all but it's a shame to have to run two radios to support both projects.

Alternatively, meshtastic is a more mature project so it might be better for them to add a routing layer.

@lmorchard Sadly you will realize most of them are trash and nobody uses it in actual communication because messages are unreliable and gets lost over hops. For a few weeks our local community are flashing our devices with #meshcore and it has much better message delivery rate because of smart routing algorithm and we see future there instead of #meshtastic.
