Meshtastic Messenger -The best solution for License-free off-grid Communications
Meshtastic is an increasingly popular open source project designed to be installed on compact and inexpensive off-the-shelf devices to create a mesh network capable of long range and low power networking without any dependency on the power or communications grid.
Nodes can use the Meshtastic Mesh Network to send text based communication, and telemetry data such as GPS coordinates, temperature, air pressure and humidity readings. Other features include the ability to remotely control other devices and equipment, as well as monitor sensors remotely
Meshtastic uses a communication protocol called LoRa, which uses radio waves similar to wifi but at a lower frequency, this means the signal can travel many further distances and at lower power levels, however, there is a major trade off, a significantly lower data transmission rate.
Meshtastic leverages this LoRa technology to create a mesh network of nodes that can relay messages on towards its intended recipient, allowing for a completely off grid long range communications solution
To get a node up and running and contribute to your local mesh it's relatively straight forward and inexpensive.
First, you will need to acquire the main component the node device itself, Meshtastic can run on a number of compatible devices, a full list with a complete comparison and breakdown can be found at Mesh About.com, but some of the most popular devices are the Heltec V3, LilyGo T-Beam and the Rack Wireless Wis Block
Now you simply need to flash the device with the easy to use web based Meshtastic online flasher, before powering up and setting some simple configuration settings
The primary intended use case for Meshtastic is text based communication, a simple iteration of instant messaging and SMS text messages, but without any reliance on additional infrastructure.
Text messages can be sent from one Node directly to another Node via the Nodes that make up the mesh network between them, text can also be sent to channels or group chats, and these messages will be received by other nodes which also have that channel configured.
Encrypted communication can be achieved if both nodes set a private PSK protected channel
In addition to text communication, Meshtastic also has the ability to send telemetry data over the network, the most common use for this feature is to broadcast a node's GPS location coordinates to the Mesh, this can be done privately or publicly if the latter the nodes location will also be displayed on the mesh map within the client applications. Some Meshtastic compatible devices have built-in GPS capability however on the vast majority a GPS module can be added inexpensively
Another popular typer telemetry data broadcast on the Mesh is environmental data such as Temperature, Humidity, and Barometric Pressure, to enable this function on your node you simply need to install a module such as a BME280
Other notable features of Meshtastic, referred to as modules, include Canned Messages, Sensor Detection, Remote Hardware Control, External Notifications, Store and Forward Messaging, Remote Node Administration, Bluetooth and WiFi Packet Counter, Built-in Range Testing and Much more
While Meshtastic has been around for a few years now, recently it's been growing into something really special, with the number of nodes and the size of the many mesh networks growing exponentially
As news spreads and more and more nodes come online, the power of the Meshtastic mesh network increases, along with the chances of Meshtastic remaining popular well into the future, perhaps one day even becoming mainstream

MeshAbout Discord Community: discord.gg/q2FEU8zeza Related Article: meshabout.com/converting-a-144-430-vhf-uhf-antenna-to-868mhz-for-use-with-meshtastic/ Let's convert a 144/430 VHF UHF antenna to 868MHz to use with Meshtastic To do this you will need a few simple tools, such as a pair of cutters and a craft knife, as well as a Nano VNA or comparable analyser and a SMA male to SMA male coupler ...
It gets overwhelmed when things get bad. I heard.
is there instructions somewhere to show how to set something like this up? wiring diagrams etc?
I have the gps modules and the weather modules. I am looking forward to building an outdoor unit and having it provide weather data.
WiFi is easier, more reliable, and higher bandwidth
Excellent Addition
1 hour and empty. Only will work with extra battery or adapter.
it doesnt tell you how to do it
Horn alert lol
I finally got it on Amazon!
Why would anyone want a gps tracker??
Telemetry was added for gov surveillance
Protip: strap your meshtastic to drone with long range antenna go up and transmit far away
Fine for testing, not good for stable infrastructure buildout.
How about as a VM?
Its about low spec pc man
I tried to install Bliss os 14 in my tablet laptop but the rotation is reversed, what i can do?
I put the heltec on my roof about 40 feet up with an expensive antenna and solar to charge the battery and the device loses power about an hour after sunset and then does not come back in in the morning unless I reset it. I have a fully charged 3000mah battery with a 5 volt 6 watt panel and a charger in line with the battery. My next attempt will be to use 2 batteries in parallel.
Awesome tips! Which mounted antenna is that?
What about 2cm lengh of brass connector ?
It's not free. If you consider all the parts you have to buy, it's far from being free.
Nothing is free in life except for STDs but $23 on Amazon for bare bone setup isn’t bad.
You’re comparing a one time purchase to a monthly payment to service providers. Obviously the one time purchase it going to be better. How is that bad in any way?
It’s not free, but it’s certainly not 20 a month for a phone plan. Or even more for an Internet plan
And how to connect it to Heltec v2? The pin numbers are different there
Can anyone tell me how to get the messages to alert loud on my device ? The iPhone never makes a noise.
Meshtastic seems like a pointless exercise. Maybe 50 years ago, but now !!
As someone who lives in a very hurricane prone area where cell service goes down with the power lines, (towers only have power for a few hours after the grid goes down) Meshtastic is absolutely useful when that power stays down for days, sometimes weeks.
@@BillBard fair point. Although having grown up in a cyclone area (Australias equivelent of hurricanes), I know that antennas don't generally fair well either in such conditions.
@brin57 truth. You can quickly deploy a small local network though. Certainly cover a few square miles just with units you can deploy after an even pretty quickly. I have one in a pelican style box with magnets I slap on the roof of my truck with a small solar panel, runs nonstop for weeks that way and I can stash it in the truck to prevent theft/storms from taking it away as needed.
If your LoRa settings are the same for your private channel, the public mesh will forward your messages no matter if they can decrypt them and not limited by the size of your private mesh. You can set LongFast as your Secondary channel.
Technically, you should save the csv file on the stationary mode. But I guess both ways would work
Short format and pc voice makes this very interesting topic unusable for me. Maybe it is my age.
Thanks for the feedback, hope the format grows on you 🙏
Wow, this is major!
It's Meshtastic!
So I ordered one of these and it came in but it came with zero instructions and I don’t see anyone else on the entire web with it. I’m trying to figure out how to get it meshing and working ….. anyone know anyone that knows anything about this device????
FBI and CIA are using planes to fly over mesh networks. They are doing "things" to the networks. Don't think for a moment your comms are secure.
I have no doubt they are 👍
Whatever comment I made here was a glitch of youtube and was meant to be on an entirely different video. seen it before, pretty sure its replicable if I put in the effort.. was totally off topic. This comment is just props for the algor as I did pass through and browsed and small channels can always do with the boosts. I follow James Hansen and the latest climate science, so I do not expect many people around to enjoy these widgets fairly near, but awesome idea in principle. lol
Thanks
Noticed this youtube bug too, from my observations it seems to happen (sometimes) when I navigate quickly to another video and back; the comment section for the other video will be present.
may you show any real results
I plan on redoing all my Meshtastic Shorts as longer, standard videos
what is the distance in city limits?
Mine is about a mile. From a window. Not high up and with buildings all around, so not bad.
what is data transmission rate?
Around 40 kbps I believe, hence text chat only and no voice
It’s getting more popular now 😅 Afew more in my area as gateways and we might get a few more hops
Certainly is. Thanks for watching
I thought that was what’s so great about this tech is that you can send data without gps triangulation and off grid….
Lots of options for how you can utilize this technology
I’m going to need to set up Two Repeater Nodes around town to get more people to join in the fun If I make my node public on the mqtt How do I know if it’s working for them to rebroadcast?
I'm haven't tested MQTT much, but plan to explore it in the near future. Good luck starting your local mesh
does it come with meshtastic firmware pre-loaded ? Is it officially supported by meshtastic ?
As far as i'm aware none of the supported devices come with Meshtastic pre flashed direct from the manufacturer, you could possibly find a third party reselling them as pre -flashed, and I have just checked the Meshtastic docs and it does not list this device as officially supported, however this could be due to the page not being updated recently, i'm sure others users would know in one of the Meshtastic online communities
Question, I have one of these sensors installed on my Heltec v3. When on USBC power the sensor functions perfectly, but when using a 3.7V 5000 maH battery the sensor shows false readings. Are you aware of what would cause this behavior?
Unfortunately i'm not quite sure, however if you join one of the community Discord's i'm sure someone else may have come across it if its a known issue
Honestly, given how cheap these antennas are I'd rather buy one than take an existing one and hack it. 🤷 Plus, an SWR of "3" is atrocious. Ideally aim for 1; commercial aerials seem to be around the 1.3-1.5, and (as I understand it) even a value of 2 is pretty bad.
Have to agree with you but I had a few lying around and wanted to see what I could do with it ❤️
For other frequencies and applications I would agree. However with Meshtastic/LoRa, while below 1.5 is ideal, 2 and even slightly above is quite reasonable, especially for shorter/lower gain antennas.
Liked and subscribed! Canned messages gets love too. Cool!
Thanks a bunch ❤️
Variables would be fine ... $rssi $snr $lat $long
👍 thanks for watching
Good video keep up the good work
Thank you ❤️
I'm loving Meshtastic.
Same, it's quickly becoming something special 👍
@@MeshAbout Indeed.
Iv updated to v2.3.2 on 3x Heltec V3's & 1x T-Beam, But can't find the number of hops anywhere. Do I need to enable some feature?
Thanks for the video! One question: when you show the pin-out of the rotary encoder, is that showing the encoder from the top, or from the bottom? Thanks!
Thanks for watching, it's shown with the 2 leg side to the Left and the 3 leg side to the Right
sir can you give me brief expalin how to intergrate sensor and motors
While i'm sure this module could be set up for simple motor control (upon receiving a message), for sensors you may find the 'Detection Sensor' module can do what you're looking for
Is it possible to control nodes using this feature in the iOS version or just Android?
Unfortunately I can't confirm as I don't have access to a Apple device, however I'm sure if you ask in the official Discord you will get an answer within minutes 👍
I don't have the LongFast channel as my primary and I can still talk to anyone who does, even though my LongFast is a secondary channel.
As I understand it, using this method you will still be able to communicate with others using LongFast, however data such as GPS, telemetry and other data will be sent over your Primary (private) Channel
Yep @@MeshAbout
Loving these videos
Thank you, means a lot to hear that ❤️
Owww. That AI generated voice, as good as it usually sounds, was having a bit of trouble with the word "canned". #cuned
Thanks for the feedback, I can tell you're paying attention 👍 thanks for watching my video's
I'd forgotten how ludicrously expensive those sensors are on Amazon. On AliExpress, *exactly* the same thing, same price but for 3-5pcs typically.
Always better to order from AliExpress if you can afford to wait 👍
I manufacture some even the ones on aliexpress cost 1000x cost
thanks for the upload, encoders and keyboards make meshtastic great for people without phones/computers near
No problems at all and yeah ideal for standalone devices, or even simply to get a time sensitive message out ASAP
Simple and accurate! Just to add: Higher quality antenna means well tuned, and doesn't mean more powerful. You will run into issues with terrain and curvature of the earth before exceeding hardware capabilities.
Thanks for the feedback 👍
Just use your phone for gps
Thanks for commenting 👍
sadly, the impedence mismatch will eventually kill the transmitter on your device.
Thanks for the heads up 👍
I thought most antennas had 50 ohm impedance no matter their frequency, could you explain why there would be a mismatch? My knowledge about antennas is very limited and I would really appreciate it
@@ThinkingPear410 look at the "smith graph". Resistance varies with different freqs
I'm not sure. It's transmitting at 868 MHz into the correct antenna. I think it's more likely that this is simply above the frequency of the low pass filter used for 433 MHz, so it's highly attenuated. Harmless enough I would have thought?
