Really neat project, this could be used for so many applications. Nice work you really have my brain crunching further ideas and uses for something like this.
Thanks. Yup, I really could have used this during the massive storm I had last year. Shame I didn't have them charged up.
It can be put to good use in fishing boats that are out of gsm coverage as well as in the mountains and areas of difficult access.
Yup, there’s a lot of use cases.
Thanks for the 10k/m overview and complete application. Nice workshop in the background.
Thanks. Glad you enjoyed it.
Your patience with soldering frankenadapter must be incredible. Thanks for the inspiration yet again Mick.
Ha ha. LOL. Yeah, it looks a bit like that. I have lots of patience when I need something finished.
Thanks mate.
Wow... Now that's what I call a practical project. Very nice. I have some ES32s and Lora modules on the way and was going to do a similar project to talk to my controller in the cottage. Now I can send text commands and receive text replies containing the info I want. Your code would be a great start. ty Mick
Yup I remember you wanted to do that. You should be able to modify my code easily to be able to pass messages through to your cottage.
I am researching DIY Yagi antennas for the 900 MHz. No clue yet why! Just in case I want to boost the reception/transmission. Good show.
Hey Mick, interesting and very usefull video ! Thnxs for sharing and please continue the good work !
Thanks mate
I like how you teach us how to think and solve troubleshooting
Thanks mate
Very good and straight forward demo
Very nice ! Thanks for sharing!
Nice on Mick! Something I am certainly going get into come the New Year! Looking forward to more!
Thanks mate. Do you have an application you’re going to use it for? Or just hacking around?
MickMake I would like to have a long distance temp and environmental reporting system, from around 10Km away ... do I need it? Nope, but it would be really helpful! :)
If it can be done, why not?
Nice!
I was actually thinking about a project like this for personal use,
your code will certainly come in handy!
I’ll have to upload it tomorrow. Just have to sanitise it a bit, (aka remove the dodgy bits). ;-)
MickMake, sounds great man!
OK. Uploaded! Didn't take as long as I thought to clean up. I must be getting old.

You must've decide to use a second typing finger...
Ha ha.
i enjoyed this, thanks mick :)
Thanks mate.
I loved it ❤;
I’ve playing with esp32 lately, I love this Idear 😊
very useful. I enjoyed the video.
great video mate!
Thanks mate
Nice project!!
Nice stuff mate excellent
Thanks mate. Glad you enjoyed it.
Thanks for sharing 😀👍 interesting stuff
Thanks mate!
hi! can you send link for your pcb breadboard? i cant find it only with separate pin and without cutting. thank you!
LoRa looks like fun, Speaking of fun... I got your Lidar package yesterday. I was worried the device would be too big, Its a perfect size.
I'll muck around with it for a week or two or three depending on my new work hours.. Then make the 'StalkAlert' software. Should be lots of fun.
Thanks again :)
Nice! Would be good to hear how you go with it. Let me know if you need a hand.
cool one mate. Will try to imitate this project and implement one like it
Nice. Let me know how it goes.
Link for a good antenna for this?
The Swiss guy did a good video exposing many antennas are not matched to the frequency they claim.
Brilliant project Mick! Interested in see the code though, and how it manages the messaging. Did you have to write a lora sms library and the html page for SMS yourself? had a quick look around your webpage.
Just about to upload to GitHub!
Hey Tim, uploaded to GitHub. There's also some extra libs you'll need. Check out www.mickmake.com/archives/4640
Love the idea! I had a similar idea a while back that I might be working on. Looking forward to updates!
Thanks. There’s been a fair bit of interest in this project. So there’ll be some updates to it.
Great vedio :). From a great youtuber.
Thanks mate.
Hello! Any possibility of an update on this project? Been trying to build something similar only using the async web-server...
Gday Did you add Encryption support for this DIY text lora setup ?
It seems this would make a great DIY pager network
Cool, I actually know someone this could actually be quite useful for as they *shudders* don't have an internet connection or even any wiffy to speak of.
Well, I wouldn’t look at running internet services over LoRa. I’ll definitely wouldn’t be able to keep up.
Although that would be kinda neat, no I meant the chat service, no internet means they don't use FB which means they can't talk to my parents or anyone else aside from calling.
Oh, I'm sure you could do ip-over-lora, packet radio but you'd be violating the duty cycle requirements of the ISM band you use no doubt. In the EU you get typically 1% duty cycle across the 898 band. :(
Greetings from Ireland. Really cool idea. Have you range tested it yet? Do buildings attenuate the LoRa signal significantly? 😉
Thanks mate.
Yup, they do. You also need to have a decent antenna.
For a second, I thought you were serious about how you were typing haha
ROFL.
Early again for for Mick
Exellent!
Definitely buying a bunch of these for when it hits the fan here in the us kek.
This is fantastic!! So i wouldnt necessarily need a phone plan with this system. Give one to each family member and text for free!!
Well, as long as everyone understands that you wouldn’t be able to use the Phones’ SMS, but use the app to connect to the LoRa module.
I’d actually like to make it a stand-alone unit, instead of using a mobile.
Great video!
Is 433Mhz band legal to use in Australia for LoRa? I'm finding it hard to find modules that are AU915 compliant (most seem to be US915 compliant). I'm thinking of building a soil moisture sensor from my garden to my house. Any advice on which modules to use that are legal here in Australia?
does the law in australia mention anything about power output? Like if you can't get an AU915 compliant module, can you get away with 433Mhz with lower output (< 100miliwatt or something)?
Brill, thank you
Thanks mate
I'm wondering if we can use this as communication device when we are at camping and no mobile signal is on . Just wondering if it can work with more than one devices
I've a side project doing something similar - great minds Mick!
Nice! Yup, it’s one that’s been on the back-burner for a while now.
Did you do any range tests? I think it'd be an interesting video to see how far you get in an urban vs open environment, Andreas has had some Swiss/German open environment stuff but nothing in an urban environment :/
Range decreases substantially in urban areas, which tends to be rectified with multiple gateways, but yup would be interesting to see. I was going to do a maximum range test like Andreas, but alas he beat me to it.
hi Sir, Can you do this project in detail?, I mean every steps thanks!
Hi, I like your project.Do you have any idea how can I read RSSI beside getting sms, so I can use this device as LoRa field test device?
It started working fine. I put serial. in front of println and print command. Range is about 16 km. interesting project. Next i coding keyboard and screen.
could you please send some tutorial links of how to setup lora
Is it necessary at the reciever side also, LORA based system should be there?
Is it not possible, via some algorithm, i just connect my phone via lora network and can able to call and send sms to anyone? (Like in some emergency conditions, can message or call to police etc.?)
Nice one Mick. Would like to get wifi and lora and then wifi and lorawan working on esp32's simultaneously so curious to see what libraries you settled on and how they worked? You planning to show us under the hood? Thanks for the vid, Garry
Thanks mate. Yup, I've just uploaded to GitHub. Check out my website for all the other extra stuff.

Champion! Go raibh maith agat :) Think you got the Oirish before, no?
I had an Irish mate who taught me two useful phrases:
conas tatu. mo chara
And
póg mo bhun
The latter gets me into trouble. ;-)
MickMake That's as bad as it gets, no swear words (as we know them) in Irish!
I have a question about external antennas. What are the things I need to pay attention to while buying antenna ? These modules communicate each other over 433 mhz band and, that means I need 433 mhz antenna ? is that all ? is there another parameter aside from frequency ? And another parameter is gain. More gain more distance as far as I know.
por fin encuentro el video que necesito
Can LoRa also be used as raw radio like NRF24L01 modules ? And if so, does it still have the same long range ?
Realy cool
i was wondering how feasible would it be to implement the XMPP protocol into this device so it could easily merge into XMPP services on the internet as well as use the server to server aspects of the XMPP protocol to connect/mesh multiple devices together. Is XMPP to much data to pass over LoRa? Basically make this device an XMPP server that could even share its connection over wifi with more than one device and link to other devices over the LoRa connection. Love these gadgets and the possibilities of them. NICE work MickMake :-)
Thanks mate.
I think pretty feasible to implement XMPP. From memory there was something someone started a while back to do just that, but it never got off the ground.
I'm surprised really.
I need help. what did I do wrong? gives an error code to the htmlServer page under PRINTLN (MyIP).
Hi Mike. Please forgive me if this has already been asked. What do you figure the bandwidth of this setup would be roughly?
LoRa can handle up to 512Mbit/s. How that translates to actual throughput is another thing entirely.
You also need to take into account that LoRa wasn't designed for sustained transmission.
The recording is several years old. Is there no better solution now? If so, where can you find them?
Im bit confused, you made need two device Lora for between two devices communicate on message? not show two devices PCB?
Nice bit lora modules hadn't thought about those yet but ok
I am very intrested on ESP32 and LoRa. Can you suggest me an Arduino IDE-alternative (maybe any rtos or other platform), in order to achieve better battery life?
Would this work Ai-Thinker Ra-02 LoRa module work with Rapberry Pi? what is data transmission rate you had seen?
Certainly would! The data rate is dependent on many factors, but don’t expect Ethernet type speeds out of it. It’s only designed for low speeds.
Awesome!
Thanks mate.
Can't i connect them to my wifi network and make a LoRa Repeater
how can you coverage in city? whats fav frequiency and SF values?
im going to put a balloon in the air with a LoRa node on it so that i can have multiple devices on the ground communicating with each other
im going to put an arduino mini in a small project box with a keypad on it and an lcd and have it connect to the main balloon which will allow it to send messages to other LoRa comm devices
Nice! There was a recent world record for LoRa transmission involving balloons.
might be time to get started on this project......
Any tips for sourcing the 433MHz antenna and the DIL converter board?
It can be a bit of pot luck sometimes. I’d check out BangGood, ICstation, AdaFruit, SparkFun, DFRobot, Seeed Studio, etc. There’s tonnes around.
where do you got this converter to standard pitch board? The yellow one?
This was actually one I found from a local electronics store. Little Bird Electronics.
You only need an app, because if you are not aware of it from a browser, we can not know one or another notification from sender.
Yes correct. Also the browser needs to be running all the time to alert you of a new message. You’ll still get them, but just won’t be alerted.
Hello, thank your for share, and i'am upload code with esp32 do not working?
Please help advise.
Thank you
It’s probably about time I revisited this!
Can we use NodeMCU for same code
Hi, I'd like to use this WITHOUT the WIFI. Just a 3.5" touch screen on each lora device to type out SMS and send. Any Ideas?
There’s quite a few people come out with some polished products based off my idea. If you head over to Tindie, there’s quite a few
Hi. Do i have to load some code on RA-02 or i just connect it?
Hey man! Greetings from Norway!
I'm looking around for parts and ideas for a project of mine. I want to create a set of "walkie talkies" for my kids (boys 6 and 9). So some kind of IM device with an OLED screen and a tiny keyboard.
Been thinking about using LoRa, ESP, or ZigBee, but yeah, .. u get the Idea?
What would you suggest? I think 433 - 900MHz is good for penetrating walls etc, plus distance. Please let me know if you have any tips on how to get this happening, or if you know of some projects, please do tell! I'd like it to be like two small devices with a numpad (old phone keyboard) or a mini mini keyboard, a small 3-4 inch display and maybe a small speaker for incoming chat.
Would you like to help me out?
I think you send simple lora messages, but not sms because sms use mobile phone antenas. Am I right??. A Question please. Is it possible for someone using some tecnology to be in 4g network without phone card. Thank you.
hi, i just bought a module esp32 lora oled 0.96 inch TTGO frequency 433h hz and I happen to do the same thing as you. But the signal is too weak to transmit a message in a building.
This is where correct antenna design comes in handy! Some of the cheaper modules don’t have a decent antenna.
in fact I did not understand the decent antenna. Can you explain me or send me same picture .
Can you describe by model name or put link to the converter and antenna?
is there a chance to use this module to built long distance rc remote controller? For rc car,? if it posibble it will be a very chip solition.
Absolutely. I think some people have done just that.
Yes. Frsky has released a module called R9M you plug into your radio, then use the R9 recievers. I use R9MM and fly kilometers away!
how to send sensor output from raspberry to node mcu using lora RA-02...do u have any methods for this.......also i want to know how to send data from node mcu to iot for visualisation
No, I haven't looked at doing that. Like anything, there's many ways of doing it. Hmmm. I think +Andreas Spiess has a couple of videos on this...
th-cam.com/video/duwUwXt-hs8/w-d-xo.html
th-cam.com/video/YahFRqf-rFA/w-d-xo.html
Brilliant project mate. I just want to start the work with LoRa. I found this project the real start with LoRa so if I want to the firmware you wrote then where can I get the firmware code to test run it?
Hope I receive a reply mate?
The firmware is up on my GitHub page.
github.com/MickMake/Project-LoRaSMS
Are you tested maximum long rang ??
first
let me say i enjoy your videos
secondly
is it possible to great a repeater to make it go ferver
is it possible to set up so meny can use it (each user has there own acount)
if last one possible would it be possible to make it were you have to ask the admin (owner) for a user name (to prevent colitions)
so basicaly i would like it were you can use it like a true sms mesaging system with possibly endles amount of users
Thanks mate.
This is what LoRaWAN is aiming to achieve. The getaways will propagate messages through the network.
0:50 What is a wih-fee access point? Did you mean a wye-fye access point?
What is the URL to your web site and why didn’t you give it out in your video.
Hi John. The URL is in the TH-cam description, also on the TH-cam cards, (if you're looking on a desktop), but here it is as well - www.mickmake.com/post/sms-lora-long-distance-sms-without-4g-project
Sir, I have some doubts regarding this. Where can I contact you?
I dont need any sort off internet connection for this right?
Also is it connectible to mobile phone?
Very intresting I'd love to learn more about this could this even be capable of using sound hmm wonder.
Not really. LoRa is designed for low transmittable data. That is: Something that lives out km away transmitting data once an hour or even once a day.
You can *theoretically* use it for audio, but YMMV and you may have the FCC guys-in-dark-glasses appearing at your doorstep.
MickMake Excellent video!!! I understand the concept however i feel that my skills are currently inadequate to successfully complete this project. Would you be willing to make and sell 2 units in a nice package?
Good day Mick. Can this have multiple access from different end users?
This is something for software, but yes... possible.
I haven't actually done anything more on this project unfortunately.
@@MickMake Why do I get fatal error in util/atomic.h? it said that I have no such file or directory?
I am not able to open his website... It says it's forbidden....pls help
Check his GITHUB at github.com/MickMake/Project-LoRaSMS
Gday Did you update this project ?
How do I actually send the messages? I’ve got the hardware working and I’ve connected to the WiFi network from the fire beetle. Where do I go to send the message?
You need to connect to the FireBeetle access point and then go to the inbuilt web page and you can send messages from that.
MickMake Im new to all of this, how would I access the inbuilt webpage?
You can open up your browser to 192.168.0.1/ (I think from memory.)
This would actually be amazing for 3rd world countries without mobile phone access
Yup true
I would like to extend this with using a small screen for text messages and a keyboard!!!!
And bluetooth and a application. But also wifi for those apple fans.
Snaponair has a pcb for this if that helps
hi to all!
does somebody know what is different between ra-01 and ra-02 modules?
Essentially one has a spring antenna and the other a uFL
@@MickMake thank you!!!
i can't emphasize enough how much of an upgrade the platformio ide is compared to the Arduino ide. Automatic download of the esp toolchain. Selection between standard Arduino code or native c code. (While using atom) automatic selection of the necessary com port and the needed baud rate. Better colored theme. Code completion. Yes code completion.
I tend to not use IDEs at all and just go for console based development. I use the Arduino IDE for developing projects like this as it’s the most popular IDE for on-boarding people. But I should do a video on platformIO. It’s come a long way.
Can i transmitt sound through rf modules or lora modules? Like a phone call?
LoRa doesn't provide enough bandwidth. Wifi can, but good luck with getting respectable range
LORA module is Half duplex right.?
Corrext
what was the range?
Can you share your code please? github not found!
can this be used as a wifi repeater?
Not really. It doesn’t have enough bandwidth and it’s not designed for it really.
Awesome.. Go for an Ionic 3 app! Would look nice.
Sounds like a good idea.
Can i use nodemcu esp8266 V3?
Any progress to this?
Eating that cereal daily for decades will give you diabetes.
Ah but this cereal is chock full of good bits!
Should be doable on the ESP8266 as well right? Want to give this a try too
It should be quite doable.
It's not actually SMS, but still neat. Thanks for the video!
Yes, true. Thanks mate.
