Rutgers University Confirmed: Meshtastic and LoRa are dangerous

In 2020, I was the first KZbinr to make a video about “Meshtastic,” created by Kevin Hester. The project name was a merge between Mesh and Fantastic. Already then, I loved the project. But why is it the “most dangerous LoRa project”? Here is the proof: My video was included in a study titled “NETWORK-ENABLED ANARCHY” by an organization featured by the US government under the topic “instructions for encrypted messaging”. So stay tuned when I show you what you can do with it even if you have a normal profession.

@@jordan3636 The government, with the help of big tech, is attempting to silence every dissenting voice. It is this censorship that idiots like you are defending. It is only by removing the ability of governments and big tech to censor people that we have a chance to remain free. Furthermore, a decentralized and private system cannot be taken over by any faction. Such a system will allow people of every persuasion to communicate, and there will be no way to stop them. One of the major factors in the destruction of Soviet control over Eastern Europe was the ability of those opposed to Soviet tyranny to communicate using fax machines. It was this decentralized (and largely secure) method of communication that allowed these people to coordinate anti-Soviet activities. Only a tyrant (or the tool of a tyrant) wants to prevent people from communicating with each other without interference.

People very often forget that privacy and security are very hard to balance; but I digress. So, when they ask WhatsApp for data and WhatsApp doesn't comply, they block WhatsApp in the entire country (I'm not sure how they're able to do that, but they do). That's a big thing for WhatsApp, for they are VERY strong here. They're the main communication channel in the country, by far. There are maps showing this in the web, you can look for it. So, this goes on for 1-2 days, and then the block is lifted. How? We may ask. Well, WhatsApp, somehow, complies. Let's say that, for WhatsApp, end-to-end encryption is very easy to break if you can clone a phone.

I guess a lot of it boils down to I was already looking at stuff like this simply because there was absolutely nothing they could do to stop it, so I already factored them out of my thinking. Generally, I was looking at a sort of hybrid protocol where a lora mesh could be used to distribute keys and routing information for higher bandwidth services. Use the lora mesh to build the VPN and then route the big data through that.

Fortunately, such low power devices cannot harm the human body at all. You usually need at least a microwave oven to do so ;-)

It's not so much fear of a "free public" but fear of being unable to detect "naughty" communications (avoiding using the word in case YT blocks my comment). It's a valid fear, although I don't get how lora/meshtastic makes this any easier. I would have thought it was vastly quicker and easier to just slap together a custom encrypted messaging platform and take advantage the existing internet infrustructure than to equip every "naughty" person with a custom lora communicator.

Hey, I've been doing some deep dives into LoRa and ESP32 recently, and remembered that, in one of your videos, you talked about the ESP32 losing connectivity/memory when it goes into deep sleep/wakes from deep sleep, and therefore, you were using an Atmel solution that didn't have that "feature". I was just watching some videos on ESP32 deep sleep, and found that there is a way to declare variables and preserve memory between deep sleep/wake cycles, and it made me wonder if that just hadn't been implemented yet in the firmware - the ability to remember the connection details between startups.

[@bloginoobs]

Any article related to this?

[@tarakivu8861]

I'd imagine that feature being used now. afaik it uses the RTC-Memory right? Thats how i preserve data when sleeping. Alternatively you can use flash to persist data on power-loss, but the flash has limited write-cycles (i think a few thousands)

@@bloginoobs Look for the RTC_NOINIT_ATTR attribute to remember variables between deep sleeps. Connection states are preserved in more shallow sleep states on the ESP32.

That was mentioned on the vídeo were he installed a sensor o the mailbox. But that problem only exists if you want to use a network like thethingsnetwork because there is a join procedure. If you build your own lora network that is not a issue.

attaching a repeater or router node to a kite 400 feet up in the air, can create a mesh range that is hundreds of square miles. The fact that sensor data and GPIO control can be a payload, it is certainly possible to remote trigger a dirty bomb quite far away from a target. I have flown a router node on a kite and driven MILES away and had excellent signal on a range test. A lightweight gain antenna made out of 300 ohm twin lead, or other wire for 915MHz is quite small and can fly on the kite payload quite easily.

[@AndreasSpiess]

As said in the video, the range is huge if you can create a line of sight, also with the stock antennas supplied with the boards.

I like to tinker with electronics, but this is way out of my knowledge spectrum. And I wanted to ask a couple of questions about LoRa's capabilities: - what is the typical range of a P2P connection in an urban environment, or say, in a mall? - what is the data throughput? is a voice call possible? low-res video call? - could one use triangulation to detect another LoRa device in a semi-close environments where GPS isn't available, like (again) a mall? if so, how accurately?

[@academicpachyderm5155]

I haven't tested in an urban environment, but based on Research you should be good for at least 300 m, but it depends on the space, of course. Figuring out location would probably be done based on signal strength similar to Wi-Fi location, but I haven't looked for something that does that specifically. Voice and video are absolutely out of the question. When respecting duty cycle in dense Networks, you're looking at measuring data in kilobytes per minute

[@FaridAbbasbayli]

@@academicpachyderm5155 Thanks, that's pretty informative! That kilobytes per *minute* was a little oof. Regarding the positioning, just identifying the distance to target is not what I was hoping for. Would be cool if by use of 2 antennae it was possible to triangulate the source of a signal.

[@academicpachyderm5155]

@@FaridAbbasbayli I've gotten speeds of 10 kb per second between two nodes on my workbench, but that was point to point in perfect conditions. One reason I put the speed in kilobytes per minute rather than bytes per second is the duty cycle limitations to make a dense network work. Any collisions have to be retransmitted, so dense meshes with lots of traffic can't guarantee super low latency transmissions.

You could cover Briar too. It works without an extra device, just your phone and without internet via Bluetooth or WiFi. Also does Blogs and Forums. If some intended recipient hasn't been reached yet, unreceived messages are stored on any device authorized to receive it and will be sent once the right recipient is within range. So basically I send Alice a message that is also addressed to Bob, but Bob isn't within range. Once Alice gets close to Bob, Alice's device will send the message to Bob.

I would like to then use node red to decide what happens when motion is detected. So in summary, use the infrastructure of meshtastic and the ease of if then type scenarios in node red. I’ve been on a hunt to find the right elegant system that doesn’t recreate the wheel. I know there are many ways to do what my end goal requires but simplicity is good. Thank you sir.

@AndreasSpiess Hallo Andreas, vielen herzlichen Dank für Deine lehrreichen Videos mit Erklärungen und ein bischen Grundlagen. Eine Frage habe ich nun aber doch zu LoRa bzw. 868 MHz Antennen - einfach aus einem Stückchen Draht. Für erste Gehversuche reicht sicher erst mal ein Stückchen Draht für Tests auf dem Schreibtisch. 299.792.458 m/s / 868.0 MHz = 34,57 cm. L/4 = ca. 8,64 cm. Nun fand ich aber auch einen Verkürzungsfaktor in Formeln von 0,95. Das wären dann für L/4 = ca. 8,19cm. Wie lang sollte ein gerades Stückchen Draht für ein RFM95 / SX1276 (868) LoRa Modul sein? Eine Idee eine etwas bessere Ant. zu basteln von mir ist, ein Deckel einer Konservendose, ein Loch in die Mitte bohren und ein Koax Kabel wie für TV SAT Anlagen zu nehmen, dann die Seele als Drahtstummel ca. 8 cm stehen lassen, den Koaxschirm an den Deckel? Ist das Sinnvoll? Macht L/2 Sinn = ca. 17,2 cm anstelle von L/4 ? Ich würde mich über eine Antwort sehr freuen. Viele Grüße in die Schweiz

Grüezi von Genf Andreas ! Silly question, In Europe is it better to use 433 or 868 Mhz ? I am thinking of buying 2 units for testing purposes. Thanks for your time and reply.

[@AndreasSpiess]

868 is used by LoRaWAN. So, if you want to try this one, too, 868 is better. Otherwise it is not too important.

[@dariuszmular1051]

I switched to 433MHz because the ranges are longer and it is possible to use an antenna cable of up to several meters with an antenna on the roof with acceptable losses. It's not possible with 868 because you will lose all the power in the cable. It didn't work in my tests. In addition, on 868MHz there is a strong direct visibility effect, and on 433 it is much less so, therefore the range is greater. The argument about interference at 433MHz no longer has any value, basically all gate remote controls and similar are already sold at 868MHz. In my city of 70,000 inhabitants, there are not many 433MHz remote controls and the meshtastic module works very well.
