That was a good morning's work ... getting #meshcore set up and installed on laptop and mobile with a repeater on the roof terrace powered by rechargeable battery/solar

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.
Tomorrow I will be working on porting meshcore to the t deck pro some more. I've currently got it working as a companion radio but need to add deep sleep, battery voltage reading and then the display.
After that it's on to a stand alone device which will take a while as there is no real UI available yet.
Speaking of kicking the tires on emergency preparedness, this should be a fun little diversion to setup and leave in my emergency kit
Meshcore-cli console tools for #meshcore v0.7 is available via pipx ! with lots of improvements on the interactive mode.
Works great on my #postmarketos phones and perfectly integrated into #sxmo ! Should probably do some wiki pages for it ...

Got 500 meters on the LoRa, through 2 walls and a hill. I need to move the antenna higher and outside.

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.

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)
@seeedstudio opened preorders for their upcoming #loramesh solar node.

This seems to be a good affordable kit for people wanting to expand their mesh without the need of power plugs ;)
It is advertised as a #meshtastic equipment and it will work great on this network.
It will also be quickly supported in #meshcore as the xiao-nrf52 core that it embeds is already supported.
www.seeedstudio.comSenseCAP Solar Node P1-Pro for MeshtasticIt is a solar-powered communication node that integrates the XIAO nRF52840 Plus main controller, the Wio-SX1262 LoRa module, and the XIAO L76K GPS module. It is specifically designed for areas without network coverage. With a built-in battery, it supports long-distance communication, precise positioning, and low-power operation. It's suitable for expanding network coverage in outdoor areas.

Working on a meshcore testbed.
I want to have several radios on the roof so I can develop in production
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.

There are several types of people who enjoy meshtastic (and the new #MeshCore):
1. Tinkerers with soldering irons
2. Preppers
3. People in desperate need of a new hobby
