022 We build a Global LoRa Mesh Network (MeshCom, Meshtastic)
ฝัง
- เผยแพร่เมื่อ 16 ก.ย. 2022
- LoRa devices have a long range and are small and cheap. Ideal for experimenting and maybe even more. Today we will build devices that create mesh networks on 70cm and, through a gateway and the internet or Hamnet, can transfer messages to meshes far away. Or to APRS. Or to e-mail. Ideal for clubs or emergencies!

Thks & I can't wait for LoRa satellite relays
Great video! Every time I watch 1 of your videos my backlog of projects increases. 😃
Thank you!
Andreas, many thanks for the interesting video! Perfect project for Winter 🥶, before running up the hills again 😉
And in spring you can place one on the highest hill ;-)
Great video as always!! Congratulations👏👏👏
Thank you!
Excellent video. Just what I was looking for.
Glad it was helpful!
I plan to also have my own gateway. Seems like a great project!
Indeed!
Great video. Happy Christmas and new year.
I am just getting started with meshtastic going to buy one maybe two heltec v3 boards and see what i can come up with.
Thank you for the info.
73😊
I hope you are QRV already...
This is a VERY interesting project! Also very interesting it uses MQTT. With that I could connect it to many other projects.
Indeed, this is simple and standardized.
I'm slowly makeing up a mesh network for off grid communication for my friends and family , and just for fun .
You are probably not the only person doing that in these tough times ;-)
@@HB9BLA ya gotta buy the devices up before we cant get cheap stuff from china anymore
Awesome and informative !
Thank you!
Wow I am more than happy. Thank you so much indeed. I am so eager to test the platform but unfortunately I low on budget maybe sometimes.
As said: The project is in its initial stage. So no hurry...
Very interesting video, combining Amateur Radio and Meshtastic.
Glad you enjoyed it!
Maybe you should sell "Strange Swiss Distortion" t-shirts! So cool. I think I already have some of the hardware. It might be a winter project for me.
Good idea! Maybe I will find a designer for the creation
Of course it will need to come in neutral colors ;-)
@@HB9BLA I will also buy one, it needs a Swiss flag somehow of course 😉
@@HB9BLAStrange Swiss Signal Modulation
That invokes a certain image in my head. I picture a grey shirt with a waterfall.
love that second channel, keep it up!
Thanks! Will do!
Hi. Does the second channel show up in the phone app if you activate it from CLI commands? Currently I cannot send messages to anyone else than the primary channel or the users directly. Thanks.
@@mihaioprea700 it should. Be sure all nodes are on the same firmware version and your config is valid. Come ask questions in the discord #help if you don't get it working.
Still haven't put in the effort for a license, but projects like these might finally do it for me.
Go for it! And report back your call sign...
You r just amazing !! I wish i had your skills in programming, but I'm in progress. I have 5 tbeam to play with on this isla, so I guess I will watch this video many times to get things to work. Best 73 SM6LNJ Peter
Have fun! This project fortunately does not need a lot of programming. Most is configuration and uploading.
Nice project. We run a Meshtastic network locally with a mqtt broker. This is more or less the same but with a further 'range', so let's try!
Cool. I think you are on the right way.
Thank you.
You're welcome!
Welcome back!
:-)
Thanks!
Thank you for your support of the channel!
Love this
:-)
I have had a solar power mesh up for 9.5 months now. Solar powered. Would love to get this connected to a world wide mesh.
Should be possible now...
Danke!
Gern geschehen!
Awesome video, I'm working to start a network in Montclair NJ - USA with my ham club and I'm getting an error message when I try to communicate with the module to send the communication lines, it's similar to the error when the ESPHome... ends in:
Exception: Timed out waiting for connection completion
BUT the ESP is closed. Not sure what else can be "blocking" the serial. meshtastic -h works but any other command related to the port such as meshtastic --port PORT returns an error.
Do you know what should I do?
Solved... I downgraded the meshtastic to match my firmware and it works perfectly fine. KD2WWU first node in America to participate! 73
I have a case where I’d like to make between 2 to 10 Nodes used as Repeaters that talk to each other, but call also be used to allow Meshtastic as well.
I’m trying to understand if one Node can do more than one thing?
As an example, I need all Nodes to have a display clock/timer and 2 push buttons like a Chess clock timer that switches between the 2 push buttons, Red and Blue. Each timer is is reset at the start from a master control, but each of the push buttons and their calculated time would be independant
A repeater is a node with a good location. It has the same function as all others. This network is a "mesh" where everybody is connected with everybody in range.
Keep in mind that this is far from a "real time" system, because its speed is slow.
Everyone get one in every town and city and lets make some mesh we can send 'hi' on
Good idea!
how do you load the drivers for the Heltec v2 board ? My pc wont recognize the boards.
Why did the mqtt fail ?
Great knowledge all around , much thanks cool guy
I do not know. But this service still is experimental and not well documented.
You know this is actually really cool if you could solar power about 50 of these. Real question? How do these fair in the field? Do they often go dead while in use like the average router, thus needing to be reset manually every other week after some time in operation?
I have yet to see a consumer or hobby grade router or a Modem from and ISP not have random issues that require a physical power cycle to be able to log into it. How are these for long term use?
If these are really good for Mesh networks? Then with placement being in places hard to get to if using solar or wind power or a combination of each? They would have to at least have a good amount of Uptime before they wig out. Do they?
AFAIK they are used as solar powered repeaters on hill-tops. But I have no experience with stability.
Valeu!
Thank you for your support!
To be honest, the 825 MHz and the 925 MHz frequencies are LICENSED to mobile providers here in my country. This the reality here in the Philippines, until Mikrotik unveiled their products based on 2.4 GHz LoRA (the same ISM frequency Wi-Fi uses).
In your country, 433 should be ISM. Meshtastic also works on 433.
Would a mail gateway open the doors for spammers? Sorry for instantly seeing the bad things, it's ofcourse an awesome undertaking
I am not sure how they do it. On Winlink there is a whitelist. Only mails from addresses which got mails from Winlink are forwarded. So you have to send a mail from MeschCom to receive mails from a particular address. But I do not know if this is implemented.
Do you have the device name, model number or more details regarding the 1 watt Lora board?
I can't seem to find a plug and flash board like the T-Beam in the market and most of them are selling only the bare module. I'm a HAM operator and would like to setup a higher power repeater node.
E22-400M30S should be one.
Its an overdub! If you look at the screen you can see he is not speaking. 3:18
It is a robot speaking ;-)
Are you going to produce a video showing how to set up a gateway? I'm in the US, and with a HAM license I can transmit up to 10 watts.
The Meshcom project changed considerably and they use APRS now. I did not check the new one out yet.
10W is most probably not helping a lot compared with the hassle to produce it because LoRa has a very high Link Budget and therefore does not need a lot of power like FSK.
How do you remove the cap from the black antenna? I want to use the same case as you...
With a heat gun.
Hello guy with the swiss accent, do you have by change knowledge of somebody using a lorawan gateway´s 9th channel (backhaul) for meshtastic...?
Could it be possible?
73
I never heard about that.
I want to build a local network of Arduino devices that control some lights. Almost like Philips Hue but over longer distances. Could a local LoRa mesh work for this? What is the easiest way to code this? I don’t think I need LoRaWAN or TTN. But I’m still looking for a well supported mesh library. The range doesn’t need to be more that 5km wide across the whole mesh. I do think I would want the messages to be encrypted so nobody can mess with it. I’m not sure what my approach should be. Radiohead maybe?
I once showed "Farm Data Relay System" on my main channel. It is no mesh, but maybe fits your needs.
At 7:50 in the video you say: "Do not install Meshtastic firmware because MeshCom binary has some presets". I have a Lilygo board with Meshtastic already installed. Do you have any tips for installing MeshCom in this particular situation? Thanks.
There's an option with ESPTool to "erase memory before flashing" or similar, that should do the trick!
I just saw the comment and hope, you were successful. I suggest the same as John.
@@HB9BLA I’ve since learned there’s also a firmware erase flash file that I was sent by someone on the Discord group, maybe also worth using.
Can this LoRa mesh network connect to a Farm Data Relay System at the Gateway?
No. They are different
Since Lora is in the ism band and not in ham frequency are crypted transmissions legal?
You can choose if you use ISM or 70cm. If you use 70cm you should not encrypt. But you have no limitations on duty cycles and are legal with your build.
I am starting up to Meshtastic with my Liligo board, i want to set up an gateway, could someone help me a bit to get this realised?
Best is to find someone with Arduino knowledge.
Morning Andreas, to wet here for detecting.
Here it is sunny again. Lots of energy from the roof...
whats that mqtt server? is this something official?
It is operated by an Austrian HAM operator
soo just like ttn?
Not at all. TTN is a hub and spoke network.
Drop these cheap modules everywhere using drones. Power them using small wind turbines and solar panels.
:-)
Are you really sure you want to do that?
We already did it ;-)
Please don't add your personal "photo" to the thumbnail - nobody want's to watch when they see that.
Andreas can you directionally hiy my Lora Helium HotSpot. Aim at 3053 center of time - Amature Iris Cricket - I went to the Arden presntation given buy the guy from Solotorn. I said a nice long range homemade wifi "gun" spacing copper discs cut from copper sheet. It was a yagi for all purpose but was a very cheap.
I do not like tha Helium network :-(
I think your right. Feels like a pyramid scheme.
I admire youre energy and so spotless easy to understad videos 👍👍👍 vy best 73s de Sm4xrt ( and for sure I Will buy a t-shirt of The swiss distortion 🤣)
Awesome, thank you! We will see...
Realized, that my gateway is on your video on the dashboard :-) Actually, I try to get some none-licensed friends up and running with Meshtastic. 73 de Daniel, OE2DHH
Cool! I hope the V2.0 will be stable.
@@HB9BLA We are Testing V2.0 with Meshtastic at the moment to support the not licensed community of friends and family. In Salzburg are no others using Meshtastic, so we have to make it more public. This version gives a big improvement of useability. After that, we are looking forward to the next meshcom firmware. 73
