Screenshot from SDRAngel of a #Meshtastic #LoRa packet on LongFast.
so... when do we get a cheap #LoRa smartwatch which 99.9% reliably gets notifications within a couple city blocks of your phone?

Over the weekend @meph added some mind blowing new features to lorapipe.
- APRS over LoRa
- Ethernet over LoRa

All of @meph 's work on #lorapipe is under MIT license.
Features like APRS over LoRa and Ethernet over LoRa serve some interesting niches we're not likely to monetize.
More than anything we want lorapipe to be a rapid prototyping tool for LoRa solutions. It's key for this to be as free and open as we can make it and I hope these features demonstrate our direction.
We'd appreciate donations towards the effort so we can knockout lorapipe v1.
Finally setup the github builder and now there's pre-release lorapipe firmware available for download!
We're building 79 different variants so testing on your favorite LoRa devices is highly encouraged!
Now that lorapipe has KISS-TNC protocol support for sending and recieving LoRa packets, it means that basically all sorts of ham radio and Linux tooling designed to talk to KISS modems suddenly work over LoRa.
For HAM radio nerds, this means things like APRS -just- work. Follow the instructions in the documentation to get started.
I suspect HAMs can bridge APRS across spectrums to ISM 433/868/915Mhz LoRa now using lorapipe. 😎

Because this KISS-TNC stuff is pretty old, it has really good support on modern Linux.
So we're actually able to setup lorapipe on two different linux boxes and form an ethernet network over LoRa!
The current rev has some MTU limits we can fix, we can also eak out probably another 2x more bandwidth too.
But as is I was able to ping, mosh and ssh over my ethernet-LoRa network between Linux computers!

PSA/rant for fellow makers: my recent order from Heltec (ordered directly) arrived with some #LoRa boards missing. I've provided shipping evidence, but so far they refuse to resolve the issue 🙄
Lesson learned: always record your unboxing! It really helps if something goes wrong.
#meshtastic / #meshcore / #LoRa people near #boston: assemble. Get me connected to your non-corporate non-ham networking. I have nothing. What is the simple beginner portable setup I could buy in the US today, either pre-made or as a kit, that ships from the US? https://youtu.be/oAo2sb8LpFc?t=12 https://cambridgemesh.net

Friend gave me a #Meshtastic node (off grid mesh network over #LoRa radio).
Feeling #solarpunk af
It's quite active in my region, I've connected with approx 86 nodes!
The chatter on main is pretty standard. A bit of a prepper vibe and some gentle trolling of said prepper.
Would be cool to link up some of the radical houses here with Meshtastic nodes. The nodes are ridiculously cheap and portable (e.g. ESP32 and an antenna) afaik.
Meshtastic also requires encryption by default for non-default channels (aka main) which isn't allowed on amateur radio in the UK.
Would easily run off a power bank solar setup. I was running it off my phone for a while whilst connecting via serial over USB-C. Super low power requirements.

We walked 2km in the forest, uphill with a ladder and some tools in order to install this Seeed Solar Node on a dead tree.
I have a good signal from home - 12km throu forest and the coverage seems to be good too.
I'll let it be here over the winter month :)

This is what the Meshcore map looks like now in the Pacific Northwest. My little node can see over a hundred repeaters on the mesh.
We now regularly have chat conversations that span several cities and we have frequent posters from Canada. A typical day sees HUNDREDS of posts in the public channel. Whole sentences and thoughts, not just "ping".
Meshcore is really taking off!
A few weeks after the Mt Rainer feat, some friends went camping and hiking all around the Orcas islands and we never lost contact at all.
At times they had better connection to the mesh while camping than they do in the city.
They hiked up Mt Constitution and were able to get direct line of sight connections to repeaters in Seattle using a typical handheld LoRa radio with an external antenna.
Over this weekend I was sadly asleep for one of my favorite effects in radio, tropospheric ducting!
I'd read a paper years ago from a team who detected ducting events in 868MHz LoRaWAN networks. These events allow end devices to reach concentrator nodes hundreds of miles away, possibly even beyond the curve of the earth.
I was wondering if we'd see this in lora meshes and turns out YES!
There have been so many really cool developments in the last month just from adoption.
Recently someone hiked up Mt Rainer and had a conversation with us on the public meshcore chat. When I went through the cougar mountain repeater's logs I noticed my repeater in Seattle's U District was actually the first hop that was connecting them to the mesh.
If that wasn't wild enough, the hiker was using a TINY radio, the Seeed Studio t1000e 🤯

The scale of meshtastics avoidance of building security into the design is pretty epic.
It allows for the formation of an entire mesh just for MITMing it.
This ONE liner here in the PKI attack means that once a node gets poisoned the key we created is based on the MAC so -anyone- who knows your MAC can read your MITM'd traffic.
When attackers run mesh marauder against the DEFCON 33 firmware they are all working together. Anyone in range can read the MITM'd DMs.
https://github.com/datapartyjs/meshmarauder/blob/channel-chat/src/lorapipe-raw-packet.mjs#L191-L193
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.
