So when it's this easy to get a MITM going things like making posts in public chats as anyone you want feels kinda low key.

But I do hope that extended warranty works out, everyone seems pretty concerned about them.

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.

I've been busy as hell this past week.

A lot of people have been asking hard questions about the security of LoRa systems when they hear about mesh radios.

I'm not one to trust the marketing so I and several friends put together two new LoRa tools to help us audit the security claims of LoRa mesh systems!

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 ｣

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!

The @atpfm folks have been singing the praises of these fairly cheap #LoRa sensors from YoLink. They don't seem to be sold in AU, is anyone aware of anything sold and supported locally (I'd prefer to avoid importing via Amazon if possible)? https://shop.yosmart.com/products/ys1603-4ys7903

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!

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.

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.

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.

Joined the Wellington mesh tonight!

Communicated with a friend ~60km away, over the Remutaka Range, using Meshtastic (LoRa @ 915Mhz) instead of the internet.

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.

Annnd my lora dev box is deployed on the roof 📡

#devhack #meshcore #lora #radio

Anyone on the fediverse tracking the #Iran internet blackout? Are there ways people there are taking to get reconnected through other routes? What about #LoRA? Are there any maps that show nodes that are connected to the general internet in the region though @meshtastic or similar?
