The first new tool is lorapipe, a firmware that runs on most consumer LoRa radios.
We've tested it a ton on ESP32-S3 based Xiao Wio boards.
This turns your lora radio into extremely minimal serial device that sends and receives packets in a dirt simple CSV format.
The radio can be tuned on the fly to switch between meshcore, meshtastic and LoRaWAN sync words and frequencies.
Printed up some cases for my little army of Heltec V3 #MeshCore and #Meshtastic nodes.

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 ｣
ok, well, flashed the Keltec v3 to #Meshcore, no problemo. But on my #grapheneos phone I can't get the meshcore app without using Aurora Store to grab it from Google Play. So did that, and then paired the device with my phone, but the app doesn't detect the device so I'm stuck with just no way to talk to it.
Well despite the lack of nodes in the area, I'm trying out #meshcore
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.
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!
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.

Some results from a week of there being a meshcore repeater on Cougar mountain.
A lot of us can now hear around 80 radios throughout the Seattle / Tacoma region.
The public chat channel is extremely busy at various times throughout the day.
I've been able to DM people in Tacoma and connect to their chat servers all the way from Seattle.
Some routes are extremely stable, meanwhile others are more flaky. It's super exciting!
I think the best thing about the home made nodes I've been using is that it's durable enough to carry almost daily. But flexible enough that I can do tons of experiments with external antennas and temporary installations in client mode or repeater.
The big one especially has crazy battery life and can run all week.
The other thing that rocks about this build is that it can be assembled with no soldering so its about as noob friendly as DIY hardware gets.
It'd be nice to be able give away a few to people who can't afford to buy the parts themselves.
$45 / $600
So feel free to throw a few bucks at me so I can scale up my LoRa expirements.

Meshcore is working well enough in Seattle that now adoption is the largest issue to having a more robust LoRa mesh network.
So if you're in the PNW area and want to build a solid handheld LoRa radio to try out meshcore I've made a bill of materials for my go to portable build LoRa plans.

#Meshcore:
https://github.com/ripplebiz/MeshCore/tree/main?tab=readme-ov-file#-hardware-compatibility
(Super simple to get started. Tries to solve flaws from #meshtastic.)
#Reticulum:
https://reticulum.network/hardware.html
(Super versatile and what I suspect to be the best tech stack. But rather complex and steep learning curve.)
In the end there should be an overlap of the most common devices.
My evaluation of resilient and disturbed means of communication started today #meshnetworks. I received my #LoRa radio board and installed #meshcore. No contact to other nodes yet, but I’m also not sure what to expect. Let’s see how it goes…
The next step will be #reticulum, but it looks too advanced to be a good starting point for me.

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.
