I watched a video earlier today of someone setting a world record for longest LoRa connection at roughly 150 miles. He was on setting 12 which I belive is long slow, and it was done with a small antenna. It's all about LoS.
The great performance of LoRa in all these 3 features (good sensitivity, low path loss, good obstacle penetration) makes LoRa a disruptive technology enabling really long range links. This is specially important in urban scenarios, with very difficult transmission conditions. To sum up, LoRa can get long ranges in Smart Cities deployments, so it reduces dramatically the size of the backbone network (repeaters, gateways or concentrators).

This is pretty cool! I've been wanting to set up a basic mesh network for my property to monitor the charge of solar batteries that charge electric fences. There seems to be a lot of value to these kind of long range blue tooth systems.
I’m glad you present ham radio as very inclusive. Hams are a perfect audience for this even if it isn’t ham band. Hams excel at patching things together. The more tools the better. Also, this tells me there are ICs that are available. So this little video highlights the technology for anything from application to hacking. Great to show these technologies! Love it!
Interesting! Two years ago I didn't really understand Mesh Networks. Today, I have a couple of mesh networks in my home, and it appears I will be experimenting with this as well. Thank you for making this video.
Just letting you know that these modules have GPS on them. Meaning that you don't even need your phone for others to see your location. The feature for your location to be pulled from your phone is there because other supported module don't have the GPS. Furthermore there is a new version of ttgo tbeam with better lora and GPS chips on them but is 7$ more expensive. Cheers
How would I get the upgraded ttgo tbeam? How do these relate to the new (to southern Nevada) WeLink laser plus radio receiver using mesh router internet access being slowing tested in America?
If these modules incorporate a GPS receiver vs using the one in your smart phone, won’t that significantly decrease the battery life since gps will always be on?
I'm an outdoorsy person along with a bunch of friends, I can see this being in our backpacks to set up a network when we're out and about. Cool vid, thanks for sharing 😁
Would like to see real world use. How it handles obstructions (trees, buildings, etc). Also interested in viewing map screen tracking multiple devices. This could be great for hiking, hunting, and more. Awesome video. More of this please. 👍
If you do any searching about LoRa you'll quickly find a very determined swiss fellow that really gets in depth and has done some very impressive long range test.
As it is far above 70cm and below 2.4 it should do far better than standard WIFI, and but not as well as like DMR on 70cm but permitting much wider bandwidth than 70cm could offer!
In the suburb aroundy house I've tested a little over a mile with one sitting in the window of my single storey house and the other holding in my hand walking. This could be easily increased by addingore nodes or placing one on high ground.
@@MishaDaBear At the same power levels (100mW for a T-Beam), text messages over LoRa at 915 MHz have much greater range than DMR on 430-450 MHz. Ham operators in the US can use the 433 MHz LoRa modules and a power amplifier if you really wanted to, but the point is that it's reliable, even at very low power.

Very interesting and informative. The way the world is going, you could imagine how such devices could be implemented and expanded to bring back a truly free internet of sorts.
“funded by the rich and eventually set up as a controlled and owned frequency” - kind of like HAM is now, requiring licensing and is heavily regulated with violators paying hefty fine, loss of equipment, and prison time?
Thanks for making this video, I’ve been looking into this, your perspective is a good data point. As you play around more, I’d love to learn along with you!
I often work in the medium height mountaous area on the Laos/VietNam border. We have a solar powered string of LoRa units that stretch from our work camp (laser range) to BO-Y (KonTum Province) where we have a cell carrier Interface. We have also constructed 3 ethnic village interconnected LoRa communications systems. Not all residents can spell so they get their friends to type for them. Since a couple of the villages straddle the border line, communicators can also save on cell toll rates.
This is actually very promising. I would like to see a node server software that could encrypt/decrypt incoming/outgoing signals and boost them to customers for use in even wider area scenarios, perhaps even a freeware signal booster that individuals could then utilize to create a free open space signal network through participant networks. This could enable the general public to become empowered enough to finally get rid of the annoying cell carrier networks that overcharge for such a simple service.
@@davidjones8942 I was speaking about possible software for computers and routers, like a ddwrt for this type of service. Something that might allow sharing of routing equipment/home servers that user nodes could be connected to to boost range and make it easier to use the equipment at even longer ranges with a peer controlled network that was secured from privacy invasion.
Found your channel through TechAirSpace Meshtastic T-Deck video. How did I not know about Meshtastic before? Our local HAM circles are out of date! Nice to see "new" HAM stuff pop up.
Nice that you cover it on a HAM channel. I had it on mine a couple of month ago. My video even made it into a security report because the technology could be used by terrorists. 73 de HB9BLA
Thanks Andreas to introducing me on these technologies, your video it’s really well detailed and all other videos regarding LoRa are full of interesting information 👏👏
Really good basic review. These devises are quite interesting. I've seen reviews that have these communicate at up to 10 miles in more rural areas, less in cities (height should get more range) and of course topography will play a part. Being a 915 MHz, there shouldn't be many other radio devises to interfere with their use. More than one group can be in the same area and separate from what I hear. Lots of potential uses. Grid/cell phone down, these will keep you connected with others in your area as long as you have a way to keep the battery charged...think solar. Being spread spectrum, others will not be able to easily copy your texts. Very few people other than your UNCLE. Great op sec. I'm looking forward to more info on these and will have to pick up a few. Thanks for the review Josh !
I've worked with LoRa before in a master to multiple slave type scenario. The amazing thing is you're only transmitting about 20mW. This is a variation of DSSS and due to the orthogonal signal spreading, the receiver can pick the signal up below the noise floor. I have been able to get up to 2 miles with the Multitech module. With a 1 watt FHSS module on the same band, with the same antenna, I get about half that range. Not all modules get the same range with the same settings. The Atmel version I tried didn't go nearly as far with the same settings. Atmel didn't know why. A node up on the roof or a pole with a better antenna should go really far.
You connected to 954c on both your tablet & phone, doesn't really demonstrate the capabilities but you explain how it oughta work! Good stuff, Thanks bud!
What an AMAZING way to get elementary kids into simple networking concepts especially LAN type. At first it will seem like a toy to them. But you can add concepts and they will be into a network of people who can expand their interests into more concepts LIKE HAM radio or other aspects of computers!

Hello. I'm just stumbled upon your channel, and find this to be very interesting. I am a tinker type guy, and my mind just explored with ideas for this. I'm not even halfway thru your video. Could you multi purpose these to relay a parameter motion sensor mesh? Maybe a wifi or Bluetooth enabled outdoor motion sensor?
That's what Dugan says he does. Uses it for perimeter security. Boogereater archive has his old streams. Check the "in order" playlist, should start with the Yankee Boogle video. He has like 5 channels with his old content up on here. Occasionally in flux. Comments on the Boogereater videos should lead you to them if you're interested. Mostly large scale global "political" discussions and self sufficiency stuff. Occasional drunk spiritual ideology streams. It's long form discussion and chat distracts him pretty often but there's lots of good info. I learned a lot anyway. He's the one who I learned about LoRa from.
Thanks for explaining I always wondered what these things were for. They look so cool just didn't no what they were for. Nice to see a video that shows how to use it and what they do.
stumbled across this, I know it is a few years old and you've done some others on this since then, but had a good chuckle when I saw the esp32/lora32 device. I have 3 of those from 2018 that have been collecting dust for 5 years, guess I found something to use them for now. Thanks!
Thought the same!! If hikers all grabbed one it would create a usable mesh on busy trails. Save a fortune on subscriptions to emergency GPS systems that are never used and provide hiker to hiker warning system for trail issues... ie. blocked trails or bear sightings 🐻
What I like about this old tech design is that you only need one node on the hub to translate to a internet connection and if its open.. all users on it can technically operate with a internet connection also through the hub system... but then we would run into bandwidth an energy concerns... hmm.. but operating with texts should always be pretty fast, especially if the text system is completely encoded and stripped down so its software decomplier on the phone meaning the bit data size can be reduced significantly.
For a Prepper neighborhood for SHTF, this technology might be very important when the grid goes dark. With God's help maybe we will not see the need but just in case a family of the close neighborhood, possibly coming together in a rural location this could be a key? Of course, Ham and CB could be there to use but still simple text messages to the community might be well served. Being Solar is also a great benefit.
indeed. just tested similar system, had no problems reaching all five receiver stations and all were at least 10 miles apart from central node. will upped the range and test again in a week or so. love the concept.
Not very far. I've been messing with these for a few years. True line of sight it can go pretty far. My record is around 13km. In town, I've been at about a mile and not been able to get a message through reliably.
We used a tbeam as a balloon tracker. Saw connections over 30 miles w/o signal loss. On ground line of sight, I have connected over 20 miles. Then I went behind a hill. There are settings you can play with to trade off between distance and bandwidth.
@@jamesfinkbeiner7262 You could send up a tethered balloon, or even stick one on a drone for intermittent long range communication. I have two of these devices on order. I'm going to try to set up a network b/t me and my friend who lives a few miles away. There definitely isn't a direct line of sight so I may have to come up with some creative solutions. It would be nice if you could stick one of these and a solar panel on a cell tower.
@@davidjones8942 I live in the deep south so its all flat land and giant pine trees. From my house, I could probably get 1/2 mile line of sight, if that much. Its maybe 5 miles as the crow flies b/t the points I want to communicate with. Around here the only hills you'll find is a dirt pile brought in by dump trucks. I may have to find a way to put them up in a tall pine tree.
How do we use this for extending range on security devices? Such a those window/door open/close modules, motion detectors, etc? It is a pain to add 10 simplisafe or ring range extenders, and what if I want one connected to a gate 1/4 mile away or 5 gates miles away? This could possibly be game changing.
I saw some that are Pi Hats. I would love to get to know more about this. I think that there is a lot of different things that can be done with this. It can be used to send thing around town. Not sure what the limit would be with the Pi Hat. With the power of the Pi and this to send between them there is a lot of things that can be done. I hope to hear more about this soon. Thank you for helping keeping up informed!
What kind of range do you expect? Is it only LOS? The RC hobby is using this in ExpressLRS. LOS is more than 20 miles. We see link quality that represents the number of packets that are getting through versus the number expected. Does it have parity checking?

Time to buy some. I don't know how you've survived without basic tool like that (I use it more than a hammer, most people own hammers). Even a cheap 40-60w rated one for $5 will be plenty for this and lots of projects, just practice on some dead electronics first and this will be easy. You could spend more (like mine is a nice one, I've went through a few cheap $3 to $5 ones through my lifetime but since I use it often I spent the cash and got a really nice $70 one that has both the soldering as well as a hot air rework on it with diaphragm pumps so I can do more advanced things like GPU core repairs and tiny SMD parts 1/5 the size of a grain of rice if needed (which in that example was bypassing the stupid timer on a heated blanket that would shut it off every 3 hours so you'd wake up at least twice freezing cold every night and never get a good night's sleep, but disable it's timing circuit by removing one part and perfect! Saved about $40 compared to their "pro model" which is the exact same thing as what I did). Also helpful for other improvements, like a simple solder mod almost doubled the power on my ebike (shunt mod, I noticed the transistors we're rated for 70 amps so I bumped it from 20 amps up to 35 amps so I still have a huge safety factor but lots more performance). Or for computer parts I add voltage bypass controls or you can do shunt mods or other stuff if you're into performance gains. But even mundane stuff like soldering a battery pack or adding external devices or anything else (like my drill now uses my quadcopter and airplane batteries so one less battery to charge, or my shaver now uses higher power LiPo for faster shaving, or my calculator now uses cell phone batteries). Also may need to solder the solar panel to the LoRa (I've also made my own solar panels from raw cells). I also use soldering a lot for fixing vehicle wiring, and really I don't know how you've survived this long without one, lol!
Great review of LoRa WAN devices and the use case you presented between two Android devices with the Meshtastic app for messaging between them. Love the shirt "Run SSB"!
I think both your tablet and phone were both associated with the same device (node 954c), no? So the test message was sent just by bouncing through 954c, and not over LoRa. The fact that the T-Beam's both showed the message indicates they were paired though, so it did have a mesh, you just weren't passing your message over it.
Quick update - I have a car node with a meshtastic radio that also has environmental sensors and voltage/current sensors wired in. This means I can monitor and data-log my car battery voltage and cabin temperature/humidity remotely. I have a t-beam at home connected to wifi, forwarding packets to MQTT, and I pull that info into HomeAssistant, allowing for really pretty graphs. I also have some solar-powered nodes that are capable of continuous operation off-grid, and they have current/voltage sensors capable of tracking battery and solar power usage/production. The project has come a long way.
Thank you, very informative. This would be a great device for a small community of friends or peepers, to join together in blackout. Will this device work with no internet or basic one to or search features? How does one protect the actual open solenoid and parts? Does it come with a protective case, or do we have to get our own like the 3D made version you mentioned.
I would love to see this combined with the emergency button project that 'Great Scott!' came up with. A handheld emergency system that can send a distress message and co-ordinates that doesn't rely on a cell network.
learned about this a couple years ago and wanted to get into it but didn't have enough understanding. much thanks and praise for this video!! these devices and mhe nesh network are a prepper's wetdream.
With the existing Meshtastic software, only one phone or tablet at a time can connect to the LoRa radio over Bluetooth. Remember, it's a mesh network. With such inexpensive radios, get one for each phone or tablet, and your network will reach even farther.
I built a couple of the meshtastic radios but found the user interface clunky. What I'm waiting for someone to do is to just provide the basic LoRa radio in a USB dongle and move all of the smarts into a laptop. In a past job, I used a USB based eval module for an 802.15 radio to provide basic tx/rx functions. It looked like a serial port to the PC and I controlled it with a python program. Having something you could plug into your laptop that would enable off-grid comm in a mesh would be pretty cool.
It’s new to me but fascinating. Have you tried a higher gain antenna? I’m an old tech retired from doing the communications that connects the world. We have a remote place that it would be fun to try it at.
First heard of meshtastic only a few days ago from S2 Underground. I like your explanation better... Very intriguing idea for a offgrid communication LAN. I'm half inclined to biy 10 of them and distribute them to neighbors! Though the setup may be more complicated, no license and use of phone or computer offers advantages over HAM or GMRS for the purpose.
Hmm, this might be interesting as a in car quick long range communication device on big tracks that have shit cell coverage (and not everyone has a license to operate more powerful radios). Hook it up to something that you can program to do colored lights in the car to let drivers know when to pit.

I’m glad you present ham radio as very inclusive. Hams are a perfect audience for this even if it isn’t ham band. Hams excel at patching things together. The more tools the better. Also, this tells me there are ICs that are available. So this little video highlights the technology for anything from application to hacking. Great to show these technologies! Love it!
Interesting! Two years ago I didn't really understand Mesh Networks. Today, I have a couple of mesh networks in my home, and it appears I will be experimenting with this as well. Thank you for making this video.
Just letting you know that these modules have GPS on them. Meaning that you don't even need your phone for others to see your location. The feature for your location to be pulled from your phone is there because other supported module don't have the GPS. Furthermore there is a new version of ttgo tbeam with better lora and GPS chips on them but is 7$ more expensive. Cheers
How would I get the upgraded ttgo tbeam? How do these relate to the new (to southern Nevada) WeLink laser plus radio receiver using mesh router internet access being slowing tested in America?
If these modules incorporate a GPS receiver vs using the one in your smart phone, won’t that significantly decrease the battery life since gps will always be on?
I'm an outdoorsy person along with a bunch of friends, I can see this being in our backpacks to set up a network when we're out and about. Cool vid, thanks for sharing 😁
That was gonna be my question so with this I just bring my phone in the words or what not and be able
To use internet and all that?
No, think of it as local mesh network of LoRa devices connected for text messaging. @@thebotfather6713
Would like to see real world use. How it handles obstructions (trees, buildings, etc). Also interested in viewing map screen tracking multiple devices. This could be great for hiking, hunting, and more. Awesome video. More of this please. 👍
If you do any searching about LoRa you'll quickly find a very determined swiss fellow that really gets in depth and has done some very impressive long range test.
As it is far above 70cm and below 2.4 it should do far better than standard WIFI, and but not as well as like DMR on 70cm but permitting much wider bandwidth than 70cm could offer!
Check out the UA-camr with the Swiss accent 😂
In the suburb aroundy house I've tested a little over a mile with one sitting in the window of my single storey house and the other holding in my hand walking. This could be easily increased by addingore nodes or placing one on high ground.
@@MishaDaBear At the same power levels (100mW for a T-Beam), text messages over LoRa at 915 MHz have much greater range than DMR on 430-450 MHz. Ham operators in the US can use the 433 MHz LoRa modules and a power amplifier if you really wanted to, but the point is that it's reliable, even at very low power.
It took me a minute to realize how I could use this but now that I get it the ideas are flowing.
Nice.
Nice to know, I was just thinking about getting my group of friends to set up a lora net
This is awesome, I hope to have a Lora mesh between my cars, and the house so that way I can remain connected even in a grid down situation

Very interesting and informative. The way the world is going, you could imagine how such devices could be implemented and expanded to bring back a truly free internet of sorts.
A sponsored internet, that will be funded by the rich and eventually set up as a controlled and owned frequency.
“funded by the rich and eventually set up as a controlled and owned frequency” - kind of like HAM is now, requiring licensing and is heavily regulated with violators paying hefty fine, loss of equipment, and prison time?
the public needed you to start this channel...thank you!
Thanks Barbara!
Thanks for making this video, I’ve been looking into this, your perspective is a good data point. As you play around more, I’d love to learn along with you!
I often work in the medium height mountaous area on the Laos/VietNam border. We have a solar powered string of LoRa units that stretch from our work camp (laser range) to BO-Y (KonTum Province) where we have a cell carrier Interface.
We have also constructed 3 ethnic village interconnected LoRa communications systems. Not all residents can spell so they get their friends to type for them.
Since a couple of the villages straddle the border line, communicators can also save on cell toll rates.
Wow that is amazing.
Good job!
This is actually very promising. I would like to see a node server software that could encrypt/decrypt incoming/outgoing signals and boost them to customers for use in even wider area scenarios, perhaps even a freeware signal booster that individuals could then utilize to create a free open space signal network through participant networks. This could enable the general public to become empowered enough to finally get rid of the annoying cell carrier networks that overcharge for such a simple service.
Isn't there already good encryption apps available for smart devices?
@@davidjones8942 I was speaking about possible software for computers and routers, like a ddwrt for this type of service. Something that might allow sharing of routing equipment/home servers that user nodes could be connected to to boost range and make it easier to use the equipment at even longer ranges with a peer controlled network that was secured from privacy invasion.

Found your channel through TechAirSpace Meshtastic T-Deck video. How did I not know about Meshtastic before? Our local HAM circles are out of date! Nice to see "new" HAM stuff pop up.
Another interesting piece of technology.
Nice that you cover it on a HAM channel. I had it on mine a couple of month ago. My video even made it into a security report because the technology could be used by terrorists. 73 de HB9BLA

Thanks Andreas to introducing me on these technologies, your video it’s really well detailed and all other videos regarding LoRa are full of interesting information 👏👏
Lora phone case with a battery included would be amazing for the prepping world.
Really good basic review. These devises are quite interesting. I've seen reviews that have these communicate at up to 10 miles in more rural areas, less in cities (height should get more range) and of course topography will play a part. Being a 915 MHz, there shouldn't be many other radio devises to interfere with their use. More than one group can be in the same area and separate from what I hear. Lots of potential uses. Grid/cell phone down, these will keep you connected with others in your area as long as you have a way to keep the battery charged...think solar. Being spread spectrum, others will not be able to easily copy your texts. Very few people other than your UNCLE. Great op sec. I'm looking forward to more info on these and will have to pick up a few. Thanks for the review Josh !
Except for the helium network 🤣
op sec? wtf? you a special agent or something? or a tool. ya thats it
Idk why I was recommended this, but I couldn’t be happier
I've worked with LoRa before in a master to multiple slave type scenario. The amazing thing is you're only transmitting about 20mW. This is a variation of DSSS and due to the orthogonal signal spreading, the receiver can pick the signal up below the noise floor. I have been able to get up to 2 miles with the Multitech module. With a 1 watt FHSS module on the same band, with the same antenna, I get about half that range. Not all modules get the same range with the same settings. The Atmel version I tried didn't go nearly as far with the same settings. Atmel didn't know why. A node up on the roof or a pole with a better antenna should go really far.
You connected to 954c on both your tablet & phone, doesn't really demonstrate the capabilities but you explain how it oughta work! Good stuff, Thanks bud!
It was multiple clips, the tablet on the right was not on 954, it was on the other. You can't have two devices on one TBeam at the same time.
@@HamRadioCrashCourse Ah alright, makes sense then! Thanks for the clarification!
LoRA makes for a good remote serial port as well, tack one onto your repeater controller.
What an AMAZING way to get elementary kids into simple networking concepts especially LAN type. At first it will seem like a toy to them. But you can add concepts and they will be into a network of people who can expand their interests into more concepts LIKE HAM radio or other aspects of computers! What an entry point to the hardware of computers and networks!

Excellent content. I want to try this for our next overlanding event when we have a convoy and base camp!
Well done. These steps still work today...
Great to hear! See you soon.
I found your video interesting and informative. Thank you for the effort. Just a note that at one point you are reluctant to reveal your geo-coordinates, understandably. However, the transceiver device on display was showing them after. Of course they may have been spoofed... I hope 🤞

Been playing with LoRa devices for a couple years now. Got some 433mhz ones and running the Meshtastic HAM settings so I could test even further ranges.
These can also be used with one of the new LoRa satellites that are in orbit if you get the 433mhz.

Hello. I'm just stumbled upon your channel, and find this to be very interesting. I am a tinker type guy, and my mind just explored with ideas for this. I'm not even halfway thru your video. Could you multi purpose these to relay a parameter motion sensor mesh? Maybe a wifi or Bluetooth enabled outdoor motion sensor?
That's what Dugan says he does. Uses it for perimeter security. Boogereater archive has his old streams. Check the "in order" playlist, should start with the Yankee Boogle video. He has like 5 channels with his old content up on here. Occasionally in flux. Comments on the Boogereater videos should lead you to them if you're interested. Mostly large scale global "political" discussions and self sufficiency stuff. Occasional drunk spiritual ideology streams. It's long form discussion and chat distracts him pretty often but there's lots of good info. I learned a lot anyway. He's the one who I learned about LoRa from.
Thanks for explaining I always wondered what these things were for. They look so cool just didn't no what they were for. Nice to see a video that shows how to use it and what they do.
These are very cool, love that T Shirt :)

@@n7ekg I want to try, maybe we can test them out
stumbled across this, I know it is a few years old and you've done some others on this since then, but had a good chuckle when I saw the esp32/lora32 device. I have 3 of those from 2018 that have been collecting dust for 5 years, guess I found something to use them for now. Thanks!
This could be good on the long trails like AT. A hiker that gets lost, and has something like this, could greatly increase their chances of rescue.
Probably not better than an emergency beacon radio.
But cool for communication with a group
Thought the same!! If hikers all grabbed one it would create a usable mesh on busy trails. Save a fortune on subscriptions to emergency GPS systems that are never used and provide hiker to hiker warning system for trail issues... ie. blocked trails or bear sightings 🐻
@@Grognarthebarb Cell phone is already in the hiker's pocket. No added expense of another device.
What I like about this old tech design is that you only need one node on the hub to translate to a internet connection and if its open.. all users on it can technically operate with a internet connection also through the hub system... but then we would run into bandwidth an energy concerns... hmm.. but operating with texts should always be pretty fast, especially if the text system is completely encoded and stripped down so its software decomplier on the phone meaning the bit data size can be reduced significantly.
For a Prepper neighborhood for SHTF, this technology might be very important when the grid goes dark. With God's help maybe we will not see the need but just in case a family of the close neighborhood, possibly coming together in a rural location this could be a key? Of course, Ham and CB could be there to use but still simple text messages to the community might be well served. Being Solar is also a great benefit.
indeed. just tested similar system, had no problems reaching all five receiver stations and all were at least 10 miles apart from central node. will upped the range and test again in a week or so. love the concept.
Just got mine in the mail today, so stoked to set it up.
What kind of range would we expect to see out of this? Of course it will vary by location/terrain. But just curious. -KD2YAY
Not very far. I've been messing with these for a few years. True line of sight it can go pretty far. My record is around 13km. In town, I've been at about a mile and not been able to get a message through reliably.
We used a tbeam as a balloon tracker. Saw connections over 30 miles w/o signal loss. On ground line of sight, I have connected over 20 miles. Then I went behind a hill.
There are settings you can play with to trade off between distance and bandwidth.
@@jamesfinkbeiner7262 You could send up a tethered balloon, or even stick one on a drone for intermittent long range communication. I have two of these devices on order. I'm going to try to set up a network b/t me and my friend who lives a few miles away. There definitely isn't a direct line of sight so I may have to come up with some creative solutions.
It would be nice if you could stick one of these and a solar panel on a cell tower.
@@oldscratch3535 you can't put one on a hilltop close to each location? Or small tower on each building?
@@davidjones8942 I live in the deep south so its all flat land and giant pine trees. From my house, I could probably get 1/2 mile line of sight, if that much. Its maybe 5 miles as the crow flies b/t the points I want to communicate with.
Around here the only hills you'll find is a dirt pile brought in by dump trucks. I may have to find a way to put them up in a tall pine tree.
Our ARES group discussed these last night. Getting one myself. In fact I think four of us will.
How do we use this for extending range on security devices? Such a those window/door open/close modules, motion detectors, etc? It is a pain to add 10 simplisafe or ring range extenders, and what if I want one connected to a gate 1/4 mile away or 5 gates miles away? This could possibly be game changing.
Those devices cannot pair and control a Bluetooth device, so it’s not possible. These appear to translate Bluetooth into LORA and back again.
I can imagine people are already working on this, go to the discord server and see who is doing what 😄
I saw some that are Pi Hats. I would love to get to know more about this. I think that there is a lot of different things that can be done with this. It can be used to send thing around town. Not sure what the limit would be with the Pi Hat. With the power of the Pi and this to send between them there is a lot of things that can be done. I hope to hear more about this soon. Thank you for helping keeping up informed!
What kind of range do you expect? Is it only LOS? The RC hobby is using this in ExpressLRS. LOS is more than 20 miles. We see link quality that represents the number of packets that are getting through versus the number expected. Does it have parity checking?

This sounds like a promising project. I would need to get the LCD panel soldered, as I haven’t any soldering equipment
Time to buy some. I don't know how you've survived without basic tool like that (I use it more than a hammer, most people own hammers). Even a cheap 40-60w rated one for $5 will be plenty for this and lots of projects, just practice on some dead electronics first and this will be easy.
You could spend more (like mine is a nice one, I've went through a few cheap $3 to $5 ones through my lifetime but since I use it often I spent the cash and got a really nice $70 one that has both the soldering as well as a hot air rework on it with diaphragm pumps so I can do more advanced things like GPU core repairs and tiny SMD parts 1/5 the size of a grain of rice if needed (which in that example was bypassing the stupid timer on a heated blanket that would shut it off every 3 hours so you'd wake up at least twice freezing cold every night and never get a good night's sleep, but disable it's timing circuit by removing one part and perfect! Saved about $40 compared to their "pro model" which is the exact same thing as what I did). Also helpful for other improvements, like a simple solder mod almost doubled the power on my ebike (shunt mod, I noticed the transistors we're rated for 70 amps so I bumped it from 20 amps up to 35 amps so I still have a huge safety factor but lots more performance). Or for computer parts I add voltage bypass controls or you can do shunt mods or other stuff if you're into performance gains.
But even mundane stuff like soldering a battery pack or adding external devices or anything else (like my drill now uses my quadcopter and airplane batteries so one less battery to charge, or my shaver now uses higher power LiPo for faster shaving, or my calculator now uses cell phone batteries). Also may need to solder the solar panel to the LoRa (I've also made my own solar panels from raw cells). I also use soldering a lot for fixing vehicle wiring, and really I don't know how you've survived this long without one, lol!
Great review of LoRa WAN devices and the use case you presented between two Android devices with the Meshtastic app for messaging between them.
Love the shirt "Run SSB"!
I think both your tablet and phone were both associated with the same device (node 954c), no? So the test message was sent just by bouncing through 954c, and not over LoRa. The fact that the T-Beam's both showed the message indicates they were paired though, so it did have a mesh, you just weren't passing your message over it.
Nope. They were connected to their own tbeam.
@@HamRadioCrashCourse How? I can't get my iPhone and Android to join the same channel.
Quick update - I have a car node with a meshtastic radio that also has environmental sensors and voltage/current sensors wired in. This means I can monitor and data-log my car battery voltage and cabin temperature/humidity remotely. I have a t-beam at home connected to wifi, forwarding packets to MQTT, and I pull that info into HomeAssistant, allowing for really pretty graphs. I also have some solar-powered nodes that are capable of continuous operation off-grid, and they have current/voltage sensors capable of tracking battery and solar power usage/production. The project has come a long way.
Thank you, very informative. This would be a great device for a small community of friends or peepers, to join together in blackout. Will this device work with no internet or basic one to or search features?
How does one protect the actual open solenoid and parts? Does it come with a protective case, or do we have to get our own like the 3D made version you mentioned.
I would love to see this combined with the emergency button project that 'Great Scott!' came up with. A handheld emergency system that can send a distress message and co-ordinates that doesn't rely on a cell network.
That would be cool! I do have a bit of a project starting here that will leverage LoRA to send some sensor data that could be used in lots of ways.
I literally have no use for this but for some reason I feel like trying to find a use for it
Express LRS radio link uses LoRa and is open source, singlehandedly (or since its FOS, multihandedly) is revolutionising radio control. Great tech.
Interesting. Any idea what kind of bandwidth they'll support between nodes?
It sounds very low bandwidth, but I too was hoping to hear this info :/
Very little. Just enough to send a few messages.

Thanks you!
Hi, can u connect multiple tablets or phones to 1 LoRa device? Thanks, N2SCD
With the existing Meshtastic software, only one phone or tablet at a time can connect to the LoRa radio over Bluetooth. Remember, it's a mesh network. With such inexpensive radios, get one for each phone or tablet, and your network will reach even farther.
@@dB-SPL thanks for the reply.
I built a couple of the meshtastic radios but found the user interface clunky. What I'm waiting for someone to do is to just provide the basic LoRa radio in a USB dongle and move all of the smarts into a laptop. In a past job, I used a USB based eval module for an 802.15 radio to provide basic tx/rx functions. It looked like a serial port to the PC and I controlled it with a python program. Having something you could plug into your laptop that would enable off-grid comm in a mesh would be pretty cool.
It’s new to me but fascinating. Have you tried a higher gain antenna? I’m an old tech retired from doing the communications that connects the world. We have a remote place that it would be fun to try it at.
I just subbed to this channel because I'm already holding onto a couple of ESP32-based LoRA devices I've had telemetry and remote control plans for. 😁
This is another hobby adjacent item that might cost me money…
Curb it now. Sounds like you have recognized a problem.
First heard of meshtastic only a few days ago from S2 Underground. I like your explanation better... Very intriguing idea for a offgrid communication LAN. I'm half inclined to biy 10 of them and distribute them to neighbors! Though the setup may be more complicated, no license and use of phone or computer offers advantages over HAM or GMRS for the purpose.
As a newcomer, main questions I have:
Range?
Data rate?
Voice capability??
Also very interested in the range from one unit to another. At 10:35 - 10:45 he loosely mentions “a couple kilometers”.
Record with LoRa is 700km it’s all bout the antenna and the surroundings
This is similar to xbee devices. Thank you for bring these to my attention. I’ll have to check these out.
A non ham was just asking me about this at the gun club yesterday. Thanks for doing my research for me, lol.
This is Great for Hiking & Camping!
It Might Even be Worthwhile for Storms!
Hmm, this might be interesting as a in car quick long range communication device on big tracks that have shit cell coverage (and not everyone has a license to operate more powerful radios). Hook it up to something that you can program to do colored lights in the car to let drivers know when to pit.
Oh yeah for sure. Mesh up all the trucks.
