One important thing to note if you're in Europe and trying to decide which frequency to use between 433MHz and 868MHz. 433MHz is lower power and is likely to have more interference from other types of devices. 868MHz is going to be the better choice unless you have a specific need for 433MHz.
@@ClacKeyTech There is a 1watt power limit in the US for the 915MHz band. If you have a ham radio license and have the ham radio mode enabled, the power limit is lifted. There are no high-powered devices though, so an amplifier would need to be connected to the device for more power.
I found these videos at the best time possible . I am very new to Meshtastic and the "getting Started" series is perfect. Very straightforward. For now I have received two RAK 4631's on baseboards and have them talking to each other. I am in rural Ohio just starting a network.

If you get 3 nodes (2 to match up with phones and 1 to be a repeater) that is a good place to start. They have complete nodes you can buy as well which may help you start a little quicker for like $55 to $60. Worth looking into. Etsy is a good place too to look.
Great job explains all this. We are rural and a couple of us want to try and develop a mesh network and cannot quite grasp the , how to communicate far using a mesh repeater. Looking forward to more presentations
I think that a meshtastic device with both input (keyboard) and output (display) is preferrable to me. I can then ditch the "smart" phone. One less device to maintain, keep track of and keep charged. Also, in a SHTF scenario I would not llke to lug around a device (phone) that can continue to track me even if no SIM card is inserted and WIFI is turned off. Yes, the smart phone still communicates with cell towers (think 911 calls) even if no SIM card is present. I hope more and more self-contained meshtastic devices come on the market with the energy saving characteristcs you described in your video. Also for a reasonable price. Still, LoRa seems to be "line of sight", given the freqeuncies used. That means there would need to be a repeater or repeaters set up to overcome obstacles like buildings, hills and woodland (trees suck up UHF signals).
All good points. I think stand-alone devices are the way to go as well and hope more come out soon. Looks like an e-ink version of the T-Deck is being worked on. Will be interested to see how that comes along.
Not into the whole shtf prepping, but if it ever comes up and the devices you have don't do what you need, consider a meshtastic device that you could plug in via usb cable to your phone and maybe blocking your phone from sending or receiving any type of wireless communication should you need to go to such extremes.

The whole idea of variable power is to not need to transmit at full power all the time. Depending on the duty cycle (which I don't know), you could shorten its life and cause interference to other nodes for not much benefit. For instance direct connection isn't necessary if you have multiple paths to a host, but boosting transmit power will unnecessarily raise the noise floor making it more difficult for all devices to communicate just so you can have a psychological 'best' node.
@@RowanHawkins My psychology has nothing to do with it. I live in an area with zero other nodes and I need to communicate with one family member 10 miles away.
Sure thing! It's really cool technology and I'm glad you're finding the videos helpful! Stay tuned for the advanced series where we'll dig deeper into it!
This is a great video for someone like me that just started learning this and is quite confused, this helped me a lot trying to figure out what to get. My only concern is that I’ve found online that I don’t have any node within miles in the rural place I live, so having meshtastic how it can help me for coms on a SHTF situation if I won’t reach anyone anyways? Fire up my HF I think will give me more.
Well I will say was so excited I found this as I've heard of Meshtastic before but never understood and I watched and I didn't understand 90% of it. I'm very green to the comms world. And still a beginner trying in the network/programming/hardware world but I've found a real passion for learning about all this. So is there any recommendations for learning all the stuff you were talking about like the chip set stuff what all that means and how it works? Sorry for sounding dumb I. Just genuinely want to learn but I obviously need more of the bare basics of what the hardware is and not Not just Meshtastic. I have no idea where to begin so if anyone has any recommendations to learn about the basics of anything in regards to how and what boards do, anything related, etc I would be seriously grateful.
@@The_Comms_Channel sounds like a great topic. I've seen some already thanks to Samy Kamkar. This is an area of the RF spectrum I'd like to explore more. I'll look forward to seeing your video.
Thank you for this channel. You have provided a lot of great information. I'm new to Meshtastic and have taken a deep plunge into the subject. I do have one question, though. Do you have a "fix" for not charging Li Ion 18650 batteries when temperatures exceed charging limits? I want to build the repeater box, but dealing with -5 F would not be good for the batteries.
I don't unfortunately other than getting 18650 batteries that support charging in low temperature. They're a bit pricey though at $30/each www.nitecorestore.com/NITECORE-NL1835LTHP-18650-Battery-p/bat-nite-18650-nl1835lthp.htm
Great video!! Could you also do a video on extra electronics necessary for UVLO with hysteresis for the lock-in without using comparators to tackle the case in which the accumulator runs out of charge? Can you share circuits or could we start a discussion to achieve such behaviour? I think this is a very important topic to address in order to have "deploy and forget" nodes without the need for human intervention to reset them.
Thank you! I totally agree on the importance of this! It may be too deep in the weeds for this particular series, but I will look into doing a video for this topic.
You could add some sort of heating device into it. I remember working on a building (electrician) and we put heating rod into gutter so that snow would melt, otherwise it would freeze and destroy it.
I read that e-paper displays use about 40% less power than traditional screens, which seems like it would be a no-brainer to have. I'll look around and see if these screens can be bought separately and installed.
They're definitely more power efficient. One thing I will say with Meshtastic though is that it's currently designed more for use with a phone and the screen interface isn't super useful at this time. Doesn't hurt to have, but I wouldn't be too pressed about having one until the UI improves.
@@The_Comms_Channel Ah, that's a great point! A screen shouldn't be needed at all, correct? Not even for setup? I'm about to pull the trigger on a few cheap ones for learning and testing.
If wanting to use the GPS/Location feature of ATAK with Meshtastic, do you need a LoRa board with GPS functionality? I would assume yes. I'm looking at the Heltec Wireless Stick Lite v3 since you've said that it has built-in GPS, but it doesn't have a screen. Otherwise, the standard Heltec LoRa v3 ESP32 looks pretty tempting with its screen. Would anyone be able to provide insight? Thanks ~🙏🏻 💯 🔥 😎
I've used ATAK, but not tried ATAK + Meshtastic yet. From my understanding though, I believe you can use your phones GPS for ATAK with Meshtastic. I'll test this out sometime soon. Thanks for the great question!
@@The_Comms_Channel Great, looking forward to it! Having to choose between a screen or a GPS is a troubling quandary, haha tbh, I'm not sure how necessary the screen is as a module, actually, since the primary interface is the smartphone but I assume it adds some validation in showing that it's on/paired
@@x_jaydn The screen isn't super useful with the current version of Meshtastic. It will show you the last message received, other nodes, ect. It is nice if you're using the canned messages feature, but outside of that, a device with no screen works fine for most use-cases.
@@The_Comms_Channel Thanks for the clarification. Maybe, I'll opt-for the no-screen version with GPS after all and see if it's implemented correctly 🤞🏻
Dumb question... Is each setup independent from others? To clarify, think of a cell tower. It's carrier agnostic so it handles connectivity for all cell providers & the more towers around, the better coverage you have. Does this hold true for these meshtastic devices? If you have a town with 15 people (who don't know each other) with these devices, does that improve coverage for all 15 people or is each person's configuration a standalone affair?🤔
Fantastic video, id like to use several of these to track vehicles on a farm but when i look up lora that i can view on an app or online via a website i only find LoreWan which is no good as thats only for sensors such a short range door sensors and the like communicating with a gateway. Is there not a lora gateway and even if you could make one out of a raspberry pi how to get the meshtastic messages and location of each device back to say my wordpress website or view on a third party site? Thanks in advance for any help and again great video and you have a new sub :) Regards Chris in Singapore
Thank you and thanks for the sub! Meshtastic supports MQTT and that sounds like it would be a good fit for what you're trying to do! I'll be doing a video on MQTT when I start getting into the more advanced usage of Meshtastic. Stay tuned!

I guess it might also include the PN532.
Thanks for the ideas! I'll look into these. I like the Geiger counter idea, but not sure how possible it will be. For the T-Deck I'm mostly after an external antenna and maybe a holder for an 18650 due to it being a battery hog
@@The_Comms_Channel I've started messing around with the model from lilygo. Do you know onshape? I can share the model if you're interested. It's not much now. I plan to release it as open source. What do you think about batteries underneath vs to the side? I'm tempted to keep it thin, but make it wider. Putting the batteries to the sides.
I've got a rough 3D model for a case in onshape. If you're interested let me know I'll share how to find the model. I seem to be having trouble posting. Perhaps issues with posting external links or something like that. I'm not sure what's up. I've posted a similar post to this 2 times already and they keep disappearing.

Has anyone repurposed Helium miners as Meshtastic repeaters or devices? Most of these miners have been obsoleted and worthless as Helium miners, but the Raspberry Pi Lora hats shold be good for Meshtastic and many of us already implemented upgraded antennas.
For the device and version that uses the 70cm band, does that basically turn your Bluetooth-equipped device into a ham radio? I thought these kind of devices were text-only, but I must be confused.
Great question. Ham radio takes many forms; voice, images, video, packet/data. So, it would essentially be a ham radio, but not in the traditional voice comm sense.
On the RAK wireless wisblock what is the name of the port for the power supply, is it a 2mm 2 pin JST? I have a 3.7v power supply and want to custom make a usb-c cable and solder that male port on the other end to give this a long battery life it has 10k mAH to last a while...
Battery: JST-PH 2.0mm Solar: JST-ZH 1.5mm Be sure to check the polarity as the ports on the RAK seem to be reversed compared to the connectors not sold by RAK Wireless.
Annoyingly bought the 433 versions in the UK early on and everyone seems to have gone for the 800mhz range ones. So buying a whole new kit as having other folks device as repeaters is very useful. Is there a way to stop the screen showing messages on it? Just ends up breaking secure coms if you leave them somewhere as a repeater. All of my current ones are the t beam...theyre pretty early. Actually considering not attaching the screen just to avoid showing messages to anyone that looks at the screen. Difficulty might be pairing....as the pairing code is shown on the screen
Not sure which device you're referring to, but I believe it should detect that no screen is installed. If so, it should use the default PIN for devices with no screens (123456)
Do the onboard weather sensors help you with troubleshooting signal or something? Having trouble understanding why you'd want that (unless you're making a weather channel lol)
I ordered the S3 Core not realizing I still need the rest of the system. No one has been able to help with where I get the rest of the system. Please explain in small words.
Hi there, thanks for your channel, what's the difference between T beam at around 50 dollars wirh 18650 support, and other one around 20~25 without 18650 support ? Just the accu holder and charge controller ? Planning to put it on solar with battery already so no real need for it. LoRa32 v2.1 for example. Thanks a lot.
Sure thing! The T-Beam has extras like GPS along with the 18650 holder. For a solar setup, I HIGHLY recommend going with a WisBlock as it uses an NRF52 microcontroller. On a single 18650 battery, you can get a week and a half of battery life on a WisBlock and only a day on a T-Beam/Lora32
@@The_Comms_Channel thanks for the fast answer, planning to do a little network around hometown for friends and family, wisblock looks pretty cool especially if that energy efficient, could try to set up a repeater on solar on my roof this way. Thanks a lot again gonna plan this 😊
Sure thing! Meshtastic for Linux is in development and you're able to use devices that have an SPI connection to the radio. I'll be doing a video on this when I get time to try it out. Stay tuned!
For the RAK in a remote/permanent setup, do you use the bluetooth to get the messages, or do you have to add ethernet or wifi? I am thinking I should put it up 30 or more feet.
If you're setting one up outside your home, you should be able to connect to it via Bluetooth. The Bluetooth range on the RAK is great and I can pick it up throughout my house with one on the roof. If you're setting one up in a remote location beyond the 200-300 feet Bluetooth range, you would need another device at home to send/receive messages and the remote one would act as a repeater.
Hi I'm in Australia and I'm getting interested in meshtastic but have some questions can it be used like wifi networks sharing videos pictures or files
For offline systems, I sure I am worried about sudden support drop. When they are unsupported, does that mean they don't get software updates or are they full dead and can't talk to newer updated ones?
Valid concern! The devs are careful to not have any breaking changes except for a major version change. For example, Meshtastic is on version 2.x and they wouldn't make any updates that would potentially break devices in the wild until version 3.x comes out and that's a ways away. Thanks for the great question!
Forgive my ignorance, I'm completely new to this technology. Are the different devices able to communicate within the same network or would the same model of device be required for all units connected? Thanks
No worries! The devices are all compatible with each other. As long as one of these LoRa devices can be flashed with the Meshtastic firmware, they can communicate with other Meshtastic devices. Thanks for the question!
Id like to try and build a pocket portable comms system. If one guy has to carry a larger case for a "repeater" or something thats fine. Id like it to try and be about 300m in range. Something i can encrypt and thats difficult to direction find. I am completely inept with any of this stuff. Any ideas?
This is true. LoRa modulation is unique though and can receive signals well beneath the noise floor for more F.A.R.S compared to standard voice or even data on AM/FM/SSB. Would love to see what LoRa could do on VHF, but the only equipment that can do it is UHF
Thanks for the question! GPS coverage is not required. This operates from device to device. GPS is just an option if you want to share your position with others.
@@The_Comms_Channel Thank you for your answer. I search a system to send a few messages to about 40 miles (with a repeater on high ground) in case of major disaster. This seems a good solution.
@@petittoto7433 Sure thing! We're doing the same thing at about that distance. I'll eventually be doing a video on planning the setup that may be helpful.

@@The_Comms_Channel How does one get the fully allowed 1 watt of broadcast power from these LoRa devices?
The whole idea of variable power is to not need to transmit at full power all the time. Depending on the duty cycle (which I don't know), you could shorten its life and cause interference to other nodes for not much benefit. For instance direct connection isn't necessary if you have multiple paths to a host, but boosting transmit power will unnecessarily raise the noise floor making it more difficult for all devices to communicate just so you can have a psychological 'best' node.
@@RowanHawkins My psychology has nothing to do with it. I live in an area with zero other nodes and I need to communicate with one family member 10 miles away.
315MHZ & 433MHZ is used in a lot of US IOT devices. Part of my alarm system uses 433MHZ.
What's the recommended replacement antenna for 915 T-Beam Supreme?
Thanks for putting all of this together!
Sure thing! Glad you found it helpful!
I just received 4 of the T1000-E Meshtastic devices.
Nice! Have fun with them!
Thank you for how you detailed this out. Just discovered some of this and so this was very helpful!
Sure thing! It's really cool technology and I'm glad you're finding the videos helpful! Stay tuned for the advanced series where we'll dig deeper into it!
This is a great video for someone like me that just started learning this and is quite confused, this helped me a lot trying to figure out what to get. My only concern is that I’ve found online that I don’t have any node within miles in the rural place I live, so having meshtastic how it can help me for coms on a SHTF situation if I won’t reach anyone anyways? Fire up my HF I think will give me more.
nicely done, new subscriber. Looking forward to learning more about Meshtastic
Thanks for subscribing!
Well I will say was so excited I found this as I've heard of Meshtastic before but never understood and I watched and I didn't understand 90% of it. I'm very green to the comms world. And still a beginner trying in the network/programming/hardware world but I've found a real passion for learning about all this. So is there any recommendations for learning all the stuff you were talking about like the chip set stuff what all that means and how it works? Sorry for sounding dumb I. Just genuinely want to learn but I obviously need more of the bare basics of what the hardware is and not Not just Meshtastic. I have no idea where to begin so if anyone has any recommendations to learn about the basics of anything in regards to how and what boards do, anything related, etc I would be seriously grateful.
You don't sound dumb at all! Here's a great video on it ua-cam.com/video/N3FXej9fqIk/v-deo.htmlsi=mXDZFsU2Gmu7xsdZ
Good introduction but I’m still confused as hell. How does all this work to accomplish communication, KISS
same here! hah
I really appreciate it! Thank you @@The_Comms_Channel
433 MHz is also commonly used in the US for ISM devices.
True. I'll probably do a video on rtl_433 and the interesting things you can pick up with it at some point.
@@The_Comms_Channel sounds like a great topic. I've seen some already thanks to Samy Kamkar. This is an area of the RF spectrum I'd like to explore more. I'll look forward to seeing your video.
Thank you for this channel. You have provided a lot of great information. I'm new to Meshtastic and have taken a deep plunge into the subject. I do have one question, though. Do you have a "fix" for not charging Li Ion 18650 batteries when temperatures exceed charging limits? I want to build the repeater box, but dealing with -5 F would not be good for the batteries.
I don't unfortunately other than getting 18650 batteries that support charging in low temperature. They're a bit pricey though at $30/each www.nitecorestore.com/NITECORE-NL1835LTHP-18650-Battery-p/bat-nite-18650-nl1835lthp.htm
Great video!!
Could you also do a video on extra electronics necessary for UVLO with hysteresis for the lock-in without using comparators to tackle the case in which the accumulator runs out of charge?
Can you share circuits or could we start a discussion to achieve such behaviour? I think this is a very important topic to address in order to have "deploy and forget" nodes without the need for human intervention to reset them.
Thank you! I totally agree on the importance of this! It may be too deep in the weeds for this particular series, but I will look into doing a video for this topic.
@@The_Comms_Channel I am happy to share my ideas and a sketch of a circuit.
Sure! Feel free to email me thecommschannel@proton.me
You could add some sort of heating device into it. I remember working on a building (electrician) and we put heating rod into gutter so that snow would melt, otherwise it would freeze and destroy it.
I read that e-paper displays use about 40% less power than traditional screens, which seems like it would be a no-brainer to have. I'll look around and see if these screens can be bought separately and installed.
They're definitely more power efficient. One thing I will say with Meshtastic though is that it's currently designed more for use with a phone and the screen interface isn't super useful at this time. Doesn't hurt to have, but I wouldn't be too pressed about having one until the UI improves.
@@The_Comms_Channel Ah, that's a great point! A screen shouldn't be needed at all, correct? Not even for setup? I'm about to pull the trigger on a few cheap ones for learning and testing.
Yep! No screen needed for use or setup. The default Bluetooth for devices with no screen is 123456
Very helpful and practical video, thanks.
Glad it was helpful!
Any recommendations and applicability in using Meshstatic devices to on commas integration on self-build RC Planes to include Drones?
Great rundown, thanks for all the info
Sure thing! Glad it was helpful!
How much do these devices cost?
$3.50
If wanting to use the GPS/Location feature of ATAK with Meshtastic, do you need a LoRa board with GPS functionality? I would assume yes.
I'm looking at the Heltec Wireless Stick Lite v3 since you've said that it has built-in GPS, but it doesn't have a screen.
Otherwise, the standard Heltec LoRa v3 ESP32 looks pretty tempting with its screen.
Would anyone be able to provide insight? Thanks ~🙏🏻 💯 🔥 😎
I've used ATAK, but not tried ATAK + Meshtastic yet. From my understanding though, I believe you can use your phones GPS for ATAK with Meshtastic. I'll test this out sometime soon. Thanks for the great question!
@@The_Comms_Channel Great, looking forward to it! Having to choose between a screen or a GPS is a troubling quandary, haha
tbh, I'm not sure how necessary the screen is as a module, actually, since the primary interface is the smartphone
but I assume it adds some validation in showing that it's on/paired
@@x_jaydn The screen isn't super useful with the current version of Meshtastic. It will show you the last message received, other nodes, ect. It is nice if you're using the canned messages feature, but outside of that, a device with no screen works fine for most use-cases.
@@The_Comms_Channel Thanks for the clarification. Maybe, I'll opt-for the no-screen version with GPS after all and see if it's implemented correctly 🤞🏻
Amazing quality video, it's stunning that you have so little subscribers.
Thanks! The channel is fairly new but growing quickly!
Dumb question... Is each setup independent from others? To clarify, think of a cell tower. It's carrier agnostic so it handles connectivity for all cell providers & the more towers around, the better coverage you have. Does this hold true for these meshtastic devices?
If you have a town with 15 people (who don't know each other) with these devices, does that improve coverage for all 15 people or is each person's configuration a standalone affair?🤔
As long as everyone has the same LoRa settings (Modem preset & Frequency) then they will all contribute to each other.
Is there a video that goes in to how this network functions, distances covered and licensing /certification or training needed?
Videos in the getting started series should cover most of this. These operate in the license free ISM band so no license needed.
Fantastic video, id like to use several of these to track vehicles on a farm but when i look up lora that i can view on an app or online via a website i only find LoreWan which is no good as thats only for sensors such a short range door sensors and the like communicating with a gateway. Is there not a lora gateway and even if you could make one out of a raspberry pi how to get the meshtastic messages and location of each device back to say my wordpress website or view on a third party site?
Thanks in advance for any help and again great video and you have a new sub :) Regards Chris in Singapore
Thank you and thanks for the sub! Meshtastic supports MQTT and that sounds like it would be a good fit for what you're trying to do! I'll be doing a video on MQTT when I start getting into the more advanced usage of Meshtastic. Stay tuned!
great overview thanks.
Glad it was helpful!
I can not get my Heltec V3 to report my fixed position to Meshmap. Could you point me in the right direction? Thanks
Video request.
-- How to use BME280 as weather station or similar sensor information in messages. Think it collects weather data and sends a message one an hour. Or if temperature drops out of some range it sends a message.
-- How to use grove or similar interface to make analog or digital sensors. Basically how to make a weather station. I want that weather station to incorporate a Geiger counter. If radiation gets to high send alarm message.
-- How to tune for battery life. A video which shows if you use setting slow long settings you get messages about ?? Second and it uses ??mj of energy. Etc.
-- How to use PN532 to only allow authorize operators to use t-deck.
Not a video, but...
-- what do you want for a t-deck shell? I'm thinking of designing one which accepts optional GPS, allows for a pile of 18650's and a solar panel. I guess it might also include the PN532.
Thanks for the ideas! I'll look into these. I like the Geiger counter idea, but not sure how possible it will be.
For the T-Deck I'm mostly after an external antenna and maybe a holder for an 18650 due to it being a battery hog
@@The_Comms_Channel I've started messing around with the model from lilygo. Do you know onshape? I can share the model if you're interested. It's not much now. I plan to release it as open source.
What do you think about batteries underneath vs to the side? I'm tempted to keep it thin, but make it wider. Putting the batteries to the sides.
I've got a rough 3D model for a case in onshape. If you're interested let me know I'll share how to find the model.
I seem to be having trouble posting. Perhaps issues with posting external links or something like that. I'm not sure what's up. I've posted a similar post to this 2 times already and they keep disappearing. Fingers crossed this one makes it.
Nice! Not sure it will allow links, but feel free to email me. Email is on the channels about page. I'm not familiar with onshape, but I'll see if I can import it to something I'm familiar with!
Has anyone repurposed Helium miners as Meshtastic repeaters or devices? Most of these miners have been obsoleted and worthless as Helium miners, but the Raspberry Pi Lora hats shold be good for Meshtastic and many of us already implemented upgraded antennas.
For the device and version that uses the 70cm band, does that basically turn your Bluetooth-equipped device into a ham radio? I thought these kind of devices were text-only, but I must be confused.
Great question. Ham radio takes many forms; voice, images, video, packet/data. So, it would essentially be a ham radio, but not in the traditional voice comm sense.
On the RAK wireless wisblock what is the name of the port for the power supply, is it a 2mm 2 pin JST?
I have a 3.7v power supply and want to custom make a usb-c cable and solder that male port on the other end to give this a long battery life it has 10k mAH to last a while...
Battery: JST-PH 2.0mm
Solar: JST-ZH 1.5mm
Be sure to check the polarity as the ports on the RAK seem to be reversed compared to the connectors not sold by RAK Wireless.
Annoyingly bought the 433 versions in the UK early on and everyone seems to have gone for the 800mhz range ones. So buying a whole new kit as having other folks device as repeaters is very useful. Is there a way to stop the screen showing messages on it? Just ends up breaking secure coms if you leave them somewhere as a repeater. All of my current ones are the t beam...theyre pretty early. Actually considering not attaching the screen just to avoid showing messages to anyone that looks at the screen. Difficulty might be pairing....as the pairing code is shown on the screen
Not sure which device you're referring to, but I believe it should detect that no screen is installed. If so, it should use the default PIN for devices with no screens (123456)
Are there any small laptop style devices with full keyboards for communication?
Do the onboard weather sensors help you with troubleshooting signal or something? Having trouble understanding why you'd want that (unless you're making a weather channel lol)
Some people use these as remote weather stations
The kind of person who doesn't trust that the cell towers are going to work also doesn't trust that the weather channel will always work.
I wish the Lilygo Eink one was available to buy
I ordered the S3 Core not realizing I still need the rest of the system. No one has been able to help with where I get the rest of the system. Please explain in small words.
Is meshatastic recommended for massive industrial IoT usecases like smart metering with thousands of meters on a single mesh?
we need a video explaining types of communication differences such as "short fast long"...
and all the rest of internal settings explained .
Thanks for the suggestion! I'll discuss that in a future video.
What is the range of these devices?
Vary a lot, between 1 and 2 km for cheap thing with short antena up to 200km with perfect condition and good device
I'm looking to set up a home repeater system that I have little to no interaction with and can be used by random strangers driving by.
14:00 Heltec LorRa 32 does this board come with a battery? Or do I have to find my own battery.
They don't come with batteries.
Where can you find these devices? It seems many places are sold out.
Hi there, thanks for your channel, what's the difference between T beam at around 50 dollars wirh 18650 support, and other one around 20~25 without 18650 support ? Just the accu holder and charge controller ?
Planning to put it on solar with battery already so no real need for it.
LoRa32 v2.1 for example.
Thanks a lot.
Sure thing! The T-Beam has extras like GPS along with the 18650 holder. For a solar setup, I HIGHLY recommend going with a WisBlock as it uses an NRF52 microcontroller. On a single 18650 battery, you can get a week and a half of battery life on a WisBlock and only a day on a T-Beam/Lora32
@@The_Comms_Channel thanks for the fast answer, planning to do a little network around hometown for friends and family, wisblock looks pretty cool especially if that energy efficient, could try to set up a repeater on solar on my roof this way.
Thanks a lot again gonna plan this 😊
@@MrKoblepot Sure thing! Good luck with your setup and feel free to reach out if you have any questions along the way!
@@The_Comms_Channel Super thanks, happy new year to you and loved ones 👍
Thank you! You as well!
Thankyou for putting the work into this video!
Sure thing!
With GPS option doesn’t that allow someone or entity to. Figure out where I’m at ?
ua-cam.com/video/2Z8_-EVwizw/v-deo.html
These looks like a great gift for your friends and homies. Do I get just the lilygo t-beam and I'm set?
The T-Beam is decent, but I recommend NRF52 based devices like the T-Echo or WisBlock
TYVM for the suggestion. How about for DIY? I have several arduino and raspberry pi4b lying around.@@The_Comms_Channel
Sure thing! Meshtastic for Linux is in development and you're able to use devices that have an SPI connection to the radio. I'll be doing a video on this when I get time to try it out. Stay tuned!
@@The_Comms_Channel subbed! i got couple of arduino and raspberry pi boards laying around and want to make good use of it...
What purpose do these devices serve?
This is the first time I've seen them.
Off grid texting between the devices using a phone while paired to them over Bluetooth
In other words, modern hobby radio communication.
Thanks for the info.
Yep, that's a good way to put it. Sure thing!
you mentioned "? Rock Land"? is that an online vendor for Lily-go?
Yes, I have links to their site in the video description
Can I make a rak one with nfr52 standalone?
Fantastic vid.
Can anything running ESPNow run meshtastic?
What do all these devices do?
For the RAK in a remote/permanent setup, do you use the bluetooth to get the messages, or do you have to add ethernet or wifi? I am thinking I should put it up 30 or more feet.
If you're setting one up outside your home, you should be able to connect to it via Bluetooth. The Bluetooth range on the RAK is great and I can pick it up throughout my house with one on the roof. If you're setting one up in a remote location beyond the 200-300 feet Bluetooth range, you would need another device at home to send/receive messages and the remote one would act as a repeater.
Nice and concise!
Thanks! Did you have any luck with getting your issue resolved?
I have to admit. I put it on the back burner for now. Thanks for checking!
Hopefully it's just a bug or something that will get fixed in an update and it will work when you try it out again.
Does anyone know where to get nrf52 in Australia
just learning this stuff. is it possible to mount in a vehicle for mobile use?
Sure can! I have one that I keep in my vehicle.
Hi I'm in Australia and I'm getting interested in meshtastic but have some questions can it be used like wifi networks sharing videos pictures or files
Not enough bandwidth. LoRa/Meshtastic is text only
Fantastic information, thank you!

What's the difference bewteen LoRa and Meshtastic?
LoRa is a digital radio protocol and Meshtastic is software that can be flashed on radio hardware that uses LoRa
For offline systems, I sure I am worried about sudden support drop.
When they are unsupported, does that mean they don't get software updates or are they full dead and can't talk to newer updated ones?
Valid concern! The devs are careful to not have any breaking changes except for a major version change. For example, Meshtastic is on version 2.x and they wouldn't make any updates that would potentially break devices in the wild until version 3.x comes out and that's a ways away. Thanks for the great question!
Forgive my ignorance, I'm completely new to this technology. Are the different devices able to communicate within the same network or would the same model of device be required for all units connected? Thanks
No worries! The devices are all compatible with each other. As long as one of these LoRa devices can be flashed with the Meshtastic firmware, they can communicate with other Meshtastic devices. Thanks for the question!
Id like to try and build a pocket portable comms system. If one guy has to carry a larger case for a "repeater" or something thats fine. Id like it to try and be about 300m in range. Something i can encrypt and thats difficult to direction find. I am completely inept with any of this stuff. Any ideas?
Will you test/show a directional/yagi antenna?
Sure can. I'll cover this in the antenna video.
Is the SX1276 / 1278 better than the 1262 you mention?
No. The 1262 is newer and has better transmit and receive performance.
Does the WisBlock do Power-over-Ethernet?
Yep! You can get the Ethernet interface add-on and there's an add-on for the Ethernet interface to give it PoE ability.
Doesn't lower Mhz travel more F.A.R.S.?
This is true. LoRa modulation is unique though and can receive signals well beneath the noise floor for more F.A.R.S compared to standard voice or even data on AM/FM/SSB. Would love to see what LoRa could do on VHF, but the only equipment that can do it is UHF
Will the ESP32 and NRF modules communicate with each other? Im sure the chirp stuff is all done by the Radio chip but just want to make sure.
Yep! They both use the LoRa protocol and are able to communicate with each other. Thanks for the question!
@@The_Comms_Channel thanks!
@@The_Comms_Channel love the videos.
@@EpiclyReckless Sure thing! I'm glad you're enjoying the videos! The next one will be coming soon.
Can i use a m5stack cardputer to mesh?
I believe so. I saw where they recently had a post on X about this
Hello, little question : so you know if Meshtastic works if there is no GPS coverage ?
Thanks for the question! GPS coverage is not required. This operates from device to device. GPS is just an option if you want to share your position with others.
@@The_Comms_Channel Thank you for your answer. I search a system to send a few messages to about 40 miles (with a repeater on high ground) in case of major disaster. This seems a good solution.

If you're unfamiliar with Meshtastic, this video gives an explanation of it ua-cam.com/video/B9rxjrSIt5s/v-deo.htmlsi=JJhvjT71mpGuc1kX
And then here is a playlist to this series ua-cam.com/play/PLshzThxhw4O5JTOACGHzYSSd3soDhoXKK.html
Why would you even want one of these devices? What can they actually do, or what are they for?
Basically, you become your own 'cell tower'. In an emergency, cell comms can get clogged or the towers themselves could be attacked by malicious actors/taken down by natural forces such as fire or tornado.
Options are always good, imo.
@@brianwelch8456 But isn't the limitation that you can only communicate with other such devides and not regular mobile/or smart phones?
