Ich habe soeben meine MeshCore Devices auf die Firmware v1.7.4 aktualisiert
Die Repeater XIAO nRF52, 3 x Promicro (1262) (via nRF OTA) und den Repeater Heltec v3 sowie den Room-Server Heltec v3 (via ESP32 OTA) .
Companion Radios: Heltec T114, RAK 4630, Seeed Studio Xiao S3 WIO, Seeed Studio SenseCAP T1000-E,
und den Heltec V3 SN-S1 Sensor-Node (mit dem BME280)
ESP-NOW: USB-Companion, Repeater und Room-Server.
You can see the code and adopt it to your situation.
It assumes that you have some number of esp32-s3 meshcore devices plugged in over USB to a Linux based device which the Action's runner can access.
Shout if you have patches, improvements or questions!
Woot, just finished implementing my first GitHub / Forgejo Actions which allows me to programmatically push meshcore builds to my radios on the roof from the comfort of my browser.
It currently only supports deploying to esp32s3 based LoRa devices so far.
MeshCore is a lightweight alternative to Meshtastic LoRa-based off-grid messaging - CNX Software
｢ While Meshtastic is by far the most popular off-grid messaging solution relying on LoRa radios, MeshCore offers an alternative as a lightweight C++ library and firmware designed for multi-hop packet routing and made for developers who want to create resilient, decentralized communication networks that work without the internet ｣
really interesting to read @nullagent thread on LORA/ #meshtastic vs his preferred #meshcore. I'm also kinda surprised meshtastic uses the MAC as the identity, and if meshcore uses an encryption key that is really a huge improvement (decouples identity from radio). anyway I'll check out what's up on meshcore down here in LA.
Good news, there's an unreal amount of interest in meshcore lately.
My community came together and group purchased 20 nodes and have rapidly been onboaring tons of new LoRa curious hackers.
It looks like I might have single handedly increased the user base of the Seattle meshcore user base by 10 - 20%.
@meshtastic I think it depends on #mesh density and terrain conditions.
Here at Lake Constance we read stations from different countries, via mountain top based repeaters but a real chat might not be possible due to packet collisions.
Let’s see if we can develop better routing or maybe a merge with #meshcore …
@booyaa @kresse it's heartening to hear of some best practices being established.
In general terms I'm curious if there's a path of least resistance to design for a #solarpunk community. To avoid it just being cottage core with solar panels I'm interested in an imaginary digital village where every household has the same kinds of thing, and find metaphors that might be an off-the-shelf hardware product. Individuals with phones are a given but that's a saturated market so not as interesting to me, although giving off-grid devices to children is an interesting topic (see also Stranger Things).
One for "letterbox" which should be more available that is also a bit of neighbourhood infrastructure and includes a repeater and some value-add for the owner like a LoRa mailbox sensor.
Another device for a "porch light" which is a client that's not always available but more likely to expect a reply from a street address when it's availability is broadcast. Maybe known to likely be a private LoRaWAN gateway.
Both anonymous (albeit obviously at an address) and not individualized.
And then maybe it would be cool to have a "hearth" device where you might have an interface that's good at integrating complementary technologies like magic wormhole and peertube to make the most of geographic advantages. Or a "notice board" where at-a-glance activity summaries of public channels and emergency services advisories are made. Either could be an mqtt broker too.
And with a general expectation that these kinds of devices are available I would hope that clarifies modes of communication in the event of a disaster scenario that can be demonstrably important to community resilience.
Lots of security and real world implications I'm sure, but I'm curious if there's anything obvious that would make #meshtastic or #meshcore unsuitable?
@octarine_wiggle yes #meshtastic works perfectly for a small mesh of locals, but you rarely know which msgs came through. As soon as people try to get a stable long distance connection over various links, it often just screams into the void.
#meshcore might be more reliable (less overhead, better routing), but less available. If you want to build up a local community give it a try, it uses the same devices and you can switch any time.
I wrote a blog post about my experience installing #Meshcore on my #Heltec V3 device and the settings you need when you are in Canada.
This is not an intro blog post to mesh in general, this assume existing knowledge about #Meshtastic

I’m going to Arctangent festival later this year and there is no cell signal so I’m taking these three Heltecs and giving two of them to close friends so I can find them at the festival!
I’m going to be running Meschore on all three (my experience of Meshtastic is it sucks all of the air out of the room and good luck sending a message to any of those contacts you found).
So if anyone else is going and wants to hop on the same mesh, this is your heads up!
#Meshtastic, #Meshcore... There is a more mature system, #APRS . Could it be more valuable as an emergency messaging system? You need a permit to use it, but it shouldn't be to difficult to get one. I wonder, perhaps Meshtastic is nice to get your feet wet, before switching to the real thing.
It's all relatively new to me. There is a lot to learn.

Glances at lora mesh network chats rooms for a millisecond . . .
How do we get meshtastic devs to stfu and stop being absolute tools, oh right just stop using their insecure pile of shit. They are the radio nerd version of SCO for the xennial generation.

Die Repeater XIAO nRF52, Promicro (1262) (via nRF OTA) und den Repeater Heltec v3 sowie den Room-Server Heltec v3 (via ESP32 OTA).
Die Companion Radios: Heltec T114, RAK 4630, Seeed Studio Xiao S3 WIO, Seeed Studio SenseCAP T1000-E über den WebFlasher.
nRF OTA: https://meshcore-de.net/meshcore-handbuch/allgemeines/adafruit-nrf52-bootloader-mit-verbessertem-ota-dfu/

Ich hab den Promicro (SX1262) Neustart nach einem Tiefentladen des Akkus mit einer Solarzelle, einem Laderegler und einem kleinen LiPo-Akku im provisorischen Aufbau getestet.
Heute Morgen war es dann so weit - der Akku war leer. Nachdem ich das Solarpanel umgedreht und zur Sonne hin ausgerichtet hatte, startete er von alleine wieder neu.
Bei einem Panel von 10 Watt und einem Akku von 10.000 mAh wird das wahrscheinlich auch im Winter nicht passieren, aber gut zu wissen, dass der Node (Repeater) später “in the wild” auch ohne manuelles Eingreifen wieder neu startet.

Je suis vraiment excité par les récents développements du réseau #loramesh dans l'ouest de la France, la liaison Nantes-Brest est quasi opérationnelle (j'ai communiqué depuis Lorient avec Clisson a plus de 170km !).
Bien sûr je suis déçu qu'il n'y ait encore personne sous #meshcore, mais @Gaulix fait un super travail avec #meshtastic et je comprends l'importance de ne pas se disperser (et meshtastic commence à adopter pas mal de principes qui ont fait leur preuve avec MC) !
Was able to connect on Bluetooth from iOS once I unplugged the device from the usb on my Mac and just plugged it in a USB charger
It looks like a great app. Much simpler to use than #Meshtastic.
However right now.. I’m alone in the north of Toronto. Chicken egg problem. Nobody to talk to
First experiment with #meshcore tonight, I flashed my #heltec v3 with the firmware at this URL and chose "Companion radio Bluetooth":
https://flasher.meshcore.co.uk/
For some reason, I can't connect on bluetooth with my iOS device (the device shows up but it just says waiting for device to connect after I click) , however was able to connect on bluetooth from a Chrome browser using this URL:
https://app.meshcore.nz/
#MutualAidRequest I'd like to build a dozen of these LoRa radios to teach people and write a complete review of meshcore in Seattle.
It'd be nice to be able give away a few to people who can't afford to buy the parts themselves.
$25 / $600
So feel free to throw a few bucks at me so I can scale up my LoRa expirements.
