The Awesome Meshtastic Off-Grid Communications System.

2 місяці тому

Meshtastic is a great digital off-gris communications system every prepper should have. Each node acts as a repeater, greatly increasing range. The system allows you to send text messages, position reports and telemetry. Devices are small and battery efficient. Very long ranges can be obtained with a bit of height and good antennas. Best of all, no license is required, it's cheap and private.

I've been playing around with these for a few days and am looking forward to trying to send some off-grid messages back to base via the mesh from a remote location around 450m ASL in Wales. I have found the Meshtastic app to be rather unstable on older Android devices and Traceroute seldom seems to work, but maybe future updates will fix at least the latter issue. I have added my base device (Heltec V3) to my IOT WiFi network rather than use it via Bluetooth (seems more responsive for both the app and web client). Early days with my experimentation, but looks promising - a good addition to the prepper kit and a bit of fun too - yet to look at the network's resilience to D.O.S type attacks etc. but if nothing else, a good substitute for SMS in areas where there's no mobile signal or the networks are down. All the best.

Nice seeing a video from you on Meshtastic! Last week I was looking into this, quite curious about it. Tomorrow I'm receiving my first T-Beam, same model you have, got it from Passion-Radio. Being from Reunion Island, I'm not sure there are users around here, but I'll see. If there isn't much activity, I'd be curious to try the MQTT stuff. Later I'll get a second device, probably a RAK so I can do a nice outside installation with a fixed antenna, couple 18650s and a small solar panel maybe. And then I'll test the range between the two.

@Liberty4Ever 2 місяці тому

I'd heard that the WisBlocks are the most reliable of the LoRa devices. The only complaint I've read is that a brown out power loss requires a manual reset, but a large enough solar panel and battery pack on such a low power device should avoid that problem. I'm using 6W solar panels and banks of four 18650 batteries for each node.

It can use them to relay messages to extend the range. Ironically this means it is an ON-grid system, but don't let the preppers hear that...

@Slay3rOne 2 місяці тому

@@vinny142 just my two cents, but Meshtastic does not rely on any centralised system that can go down and instantly break the whole network. It simply meshes devices together into a device-to-device network, so each of them can help extend the range of the others around. Unlike the phone, or internet, if the provider goes down, it's all gone. It just happenned a few weeks ago where I live after a cyclone. Annoying. So I don't know if using the word off grid is good or not here, but according to Wikipedia's definition, looks like it does. "off-grid is a characteristic of buildings and a lifestyle designed in an independent manner without reliance on one or more public utilities." from Wikipedia, mentioning "public utilities". Then if you want something that has an unlimited range from point to point without any relaying, well there is still ham radio, providing the best atmospheric conditions for a contact, appropriately sized antennas and everything. But that's something else entirely. Different systems for different usecases.

How good is it in relaying text messages across countries??? like for instance from Britain to Greece or Australia?

Then there would be no need for AIS, Iridium or unaffordable Starlink.

I like gadgets and all but this is some J6er crap. The useful range is bad, the infrastructure has to be supplied by the user. And its easy to jam. All these meshtastic videos are just cash grabs using monetized links. Again it's a cool gadget but real world its junk. Might work well for cartels and criminals in certain situations. But would fail in a fubar situations. Your screams have a longer range.

I couldn't disagree more. Range is excellent, and it would be a great asset in an SHTF situation.

What's J6? Anyway, it's a cool gadget anyway for those of us interested in radio, especially small data packets over radio, including hops. I could say I was interested in hops, but that's a different interest!
