There was a Tv series a few years back where people were always watched and analysed by a computer linked to all cameras and phones. It sent messages to this person about saving certain people. When the competing bad computer was launched, good guys had to use this type of network to communicate. Since LOS was required nodes were set on the rooftops. Might have been this tech that fueled this idea. I thought how handy this would be in a surveillance state.

[@eternalillusion]

Japan has a Constitutional ban on military secrets - so you should be able to operate a very broad band relatively powerful HF CDM, which would be undetectable, and even if detected - it would still be legal - in Japan. From there, despite laws, people would export these units to more repressive countries - like the U.S. Once there are a few thousand of these units operating around the world, the genie would be out of the bottle and secure secret communication would be possible - which would be enough to topple repressive governments who don't clean up their act. THIS could change our world for the better. Keep up the good work.

[@leapfrog4561]

Another thing I admire about japan is that the government seems to respect their constitution. The reason they didn’t shut down businesses and lock down is because the prime minister recognized that according the their constitution the government does not have the power to tell people what to do.

I am working on a new network protocol specification that includes encrypted tunnels as a core feature. The basic idea is to use latency measurements between hosts to derive addresses in several dimensions using basic gradient descent. The first node in a network becomes the origin, and every new node calculates and self-assigns an address encoding coordinates after gaining latency attestations from neighbors; all other nodes can then verify the address very quickly using the latency attestations. One of the benefits to this coordinates-as-address system is that routing becomes a matter of forwarding to the neighbor who has the lowest distance from the target address. How to make that an efficient look up is something I have yet to formalize, but I have outlined other things, like gaining guest address leases from hosts, bridging between networks, neighborhood gossip protocol, anti-spam policies, etc.

I've been in the decentralized community for a while. AtHoc networking is unreliable for the reasons you mentioned but also because lag increases with every hop regardless of distance. GoTenna mesh sought to solve this problem by allowing certain users to act as gateways and then its a matter of connecting gateways. The privacy issue is meant to be solved with encryption, but the low throughput of radio frequency usually encourages non complicated text data only. Althea mesh is more of a WiFi router and extender linking project and the mix of these two schools of thought (pocket radio and WiFi linked gateways) may be the best solution to a decentralized trust less network for we'll say protesters as an example.

I got a couple of these for christmas and came back to rewatch some of your lora videos. They have improved the meshtastic firmware a lot. You can now connect them to your wifi and have them put messages (encrypted) into an MQTT server that is then picked up by all nodes using the mqtt server with the same channel name/key over the internet and rebroadcast. Basically, I could set up a node here in Texas connected to an MQTT server, you could set up a node in Sweden connected to the same MQTT server both with the same channel names/keys and I could send a message from my phone that you get delivered to your phone. All encrypted via the mesh network and sent over the internet. Out of the box with the stock antenna it gets good range. From a shelf in my house to the other one being on the dashboard of my car, I got 1km. Bet if I install a high gain antenna and put it on a mast I can get much further. Thanks for the great videos.

So you for sure you have to define the pins used for the LoRa module and maybe change the LCD, if M5stack uses a different one. But it should not be a huge task. All LoRa modulesw seem to be supported. For the moment I do not plan another video about tis project.

[@svenjohnson2389]

I seem to recall this concept being called village radio. This was before SMS, so now with texting, this strategy could work well.

[@AndreasSpiess]

You are right. The mesh is not new. But this implementation is interesting because of its reach and cost.

Another board option, our new Turtle LoRa Board uses an STM32L4 being able to run up to 10 years on AAA batteries. This would qualify for something like this. Now the interesting part, we at RadioShuttle.de (new business organisation applied last month) working on a LoRa messenger. It is based on the Turtle board with a buzzer and gets connected to a Smartphone via an OTG cable. This allows pretty much private peer to peer messenger chat communication. The LoRa board works stand alone and beeps when a message for you or a group broadcasts arrives. We are looking for more than month of uptime for the messenger boards, once something arrives, connect your smartphone as a user interface device for the messenger (no WLAN, LTE, BLE, can work in airplane mode). The idea is, that this allows emergency communication, when nothing else works e.g. outage, areas with no coverage, etc. Great video like always, thank you Regards from Arduino Hannover & www.radioshuttle.de Helmut PS: The legal part of this topic is some more complex, I heard that the US arrested an Canadien company owner because he build a truly private Android phone with encryption. My opinion is that we should have a right of privacy, which is given by law, however the governments like to ensure that they can spy everyone (without court orders).

[@AndreasSpiess]

Great! OTG was also discussed for this video. It saves the need for BLE but maybe is a little uncomfortable for use I also think there are two use cases: One for short events where speed is more important than battery life. And another where your focus is where long standby times are more important. BTW: I like the idea of a "buzzer".

[@sunyun4425]

In the configs you can also look into changing the hardware utilization...i mean you own the hardware, why not do some debugging and test it and let us know ;)

[@atranimecs]

The cool part about this is the encryption aspect vs. traditional radio communications that can be overheard by anyone. Would be awesome if there was a low bandwidth audio protocol with client-side decompression used by the app.

[@AndreasSpiess]

These ISM bands are for sensors and not for voice coms. There are other bands for that. And LoRa is nor fast enough for voice in most of the cases :-(

[@RaimoKrauchi]

Very nice project. I would implement public key encryption on the application layer (additional to the transport layer).

Distance is your friend if you are not connected to a network...

[@deepserket4390]

do you mean an end to end encryption in channels where multiple devices can join? that's hard

[@fitybux4664]

You are talking about asymmetric cryptography in addition to the symmetric cryptography already used (with the preshared key). That's hard and you'd have to trust a central authority or have some elaborate scheme for distributing keys. Also it's very bandwidth hungry, whereas preshared keys can technically use no extra bandwidth, all devices just have your key. If you do it, it's open source. I'm sure everyone would love you for it.

I would encourage folks to try this stuff out and the meshtastic team is pretty darn cool, but know that this not at all ready for prime time. I am a techie with some serious professional experience in related fields, but I feel like I have falling down a rabbit hole trying to get this set up and ready for my community, I do not think it is going to happen. Update: The things go to sleep and wake up randomly, I am seeing so many issues and feeling overwhelmed with just how far from complete this project is. It is all being created in folks free time, so I get it, but just don't prop these things up before they are ready, cause this is not at all ready! :( Update: 5/22 - I have come a long way and have things working pretty well now. It may not be consumer friendly, but a techie with time, money, & patience can bring this to their community with some real effort on your part - I am doing it. I have wanted this sort of thing for years and this one has even more potential than what it is offering up front right now.

[@AndreasSpiess]

I agree. It seems they are in the midst of a major revision (towards 1.3) which should be ready in June. I decided to cover the project when it is ready. Currently, I was able to make it work. But it was time-consuming.

How many phones can a mesh node support? Can I pair 2 phones to a unit? Or is it one phone per unit?

The phone is paired to the node and the nodes establish the mesh.

Sending short VOICE messages with this hardware definitely will be the gamechanger. Yes, I know that LORA speed is not sufficient to send voice in realtime - but we can record and store 5-second message, transmit it (for example) in 50 seconds, and play back on receiver device. In this case we don't need any smartphones for typing our messages.

[@lawpickinglocksmith7689]

Awesome! Reminds me a bit of Packet Radio, just a bit more modern. There we used to set up bulletin boards, burned 27 series eeproms where I had to import a writer from the US and build my own eraser. If it goes over the net it will connect the world. Locally since you are in a valley the town of Hellstone may reach Mount Lampen. Say you call Rene Lutz, you will need some repeaters or nodes they call them. About half our radio club members have DMR to Wifi boxes. The DMR voice sounds horrible. For text only my all time favourite was Amtor! I even changed to a shorter call sign so I could call from VKHB VKHB...

[@AndreasSpiess]

You are right. A lot of things come back in different forms. But: I use DMR and it sounds great for me. Even made som DX to the US and Japan out of my basement ;-)

[@lawpickinglocksmith7689]

@@AndreasSpiess If you used the internet in between it is not really dx. When I lived south of Cairns I could make most of the world in short path on 20 m. Perfect for Amtor. Then I had a much better QTH with 220 degrees view. But strange most dx worked over the long path and Amtor ARQ kept colliding. Pactor never was really the same. Our club is now way under 10 members and we not only lost our DMR repeater but all the good hill locations. Would be nice to have a network independent from the internet and mobile phone system.

[@AndreasSpiess]

The DX was a joke! First I also wondered if it still is HAM radio. But the people are the same on DMR as on the other bands. So it is different from Skype or Zoom. I would not meet those people by chance.

[@asafsirin1614]

Thanks for sharing your experience. Good concept, not free from flaws though. keeping only route to the best neighbor would make communication unreliable when "standing few meters apart and loosing rf coverage". as no retransmission is assumed, or only limited number of times, packets will be dropped since no big buffer is available at the end device. pairing can be done using audible signals so led can be dropped. public wifi's could be used as bridges when no lora coverage is available (needs ciphering if security is a concern). volunteers may host lora nodes for cost of nothing ( powered from solar energy and using more efficient antennas, like it is done in mobile network). Waiting for more news. All the best!
