I worked on LoRa for master in 2016, and I have limited hardware options (LoRaWAN transceivers were dominant, and simple P2P communication was not easy). I watched your Video, and I remember these days. Thank you for the video, and I will try these setup as soon as possible (I am a PhD candidate , so free time is not possible by this Summer:). By the way, I had two options for my master: upitt and Akron. Now, I am stuck in OH:D
Thanks for the very understandable video on LORA set-up. I will note that the use of 868.5 MHz is in the European ISM band. In the USA the frequency of 915.0 MHz should be used to conform with the FCC ISM band limits of 902 - 928 MHz. This also might explain why some had intermittent data throughput issues as the use of 868.5 MHz in the USA could subject your LORA link to local interference from licensed users.
My thinking of your video delivery was inherently over-critical at first. You proved me wrong once I realized that you're talking less about theory of practice and more on functional setup. I cherish you
@~3:30 you are communicating with the device when you send it the AT+RESET command. Why then would you need to send it the baud rate command after? If the baud rate were different (than 9600) on power up, then it would not recognize the RESET. I think the baud rate command would be only for changing baud rate from default.
Hi. In the transmitter code, shown in the video, I think it is necessary to include Serial.print ("AT+SENDER=receiving port number, 1,H"; and Serial.print ("AT+SENDER=receiving port number, 1,L";
Why is NRST connected to pin 13? During program coding, there was nothing related to pin 13. Why did you connect them? Do you really need that connection? If necessary, why? Please explain.
Nice video, why do you set MODE=1 ? In REYAX AT-guide it states that your lora module goes into sleep mode. Also with the transmitting unit you do not use "AT+SEND= command any reason for that?
Thank you VERY much Paul! Trying to learn about this subject proves daunting when realize most videos on the topic don't cover the basics. You did that beautifully! You did throw me off when you skimmed over the switch to the 3.3 v boards. What makes this video great is your are very detailed in when jumper wires go where. Working on trying to set up a very similar system for my son's school farm project to send a couple weather readings (temp/humidity) to the main building. He is using Arduino too. One question is I thought Uno's and nanos had the capacity to use 3.3. v or 5v? Thanks again. We will check out your Amazon shop for future purchases.
I misunderstood what he was saying . The data bus is 5v. You'd have to get an Arduino that does 3.4 volts. Like the Spark fun Pro Micro from China which ain't cheep.
hey, i am from Australia and i watched both parts of this LORA setup, i have no idea about the whole thing but, it is understandable. i noticed that after you changed over to the 3volt setup and went for the drive, all i saw was the LED flashing, wasn't there code for the oled display that should have come up, i was waiting to see it ? I mean, there is no point having it if it isn't used.
Great video, thank you! Quick question: I'm not an engineer, so pardon if my question doesn't make sense... but is it be possible to send a tiny packet of data from the TX to the RX within 7ms or less? Thank you.
Do the arduinos not have a 3.3v power out that you could use? I ask because i am trying to do the same im just wondering if i could use the 3.3v out safely
Good explanation. I trust you didn't simply upload an LED blink program on the receiver. Wish the receiver was doing something else to illustrate communication with the transmitter.
if you use gate and limiter in your audio it needsx to be turn down because it cutting u off at times to quick and also do u need a pop filter i got one if u need one i will send u sounds like your gate is set to close to fast etc
No one seems to observe that these things use spread spectrum technology. They also are quite pricey -- seem to be for military and such. This does not appear to be targeted towards IoT or hobby.
@@jaydenclark4144 Both Uno & Nano have 3.3V regulator outputs that can power Lora. You need a resistance divider network (4.7K,10K) between Arduino Tx & Lora Rx. You can directly connect Lora Tx to Arduino Rx.
To transmit over lora do we need just the two receiver and transmitter as you used or there is a central broadcast station installed in the city that is redirecting the traffic ? I am just a bit confused with this technology
I'm impressed that it works inside a metal box with no external antenna. So this doesn't require line of sight? Now I'm wondering about using to transmit data from my beehives to a distant receiver...
Awesome video man. Learned a bunch. Brand new to this type of stuff. I want to build a camera that will be located about 3/4 of a mile away from my house. Do you think I will be able to operate the camera with that distance with a similar set up (minus blinking light plus a camera) which i want it to have live feed?
Not using Lora… a live video feed requires far to much bandwidth. Lora is designed for packets of data. If you want to transmit video signal you will need direct line of sight using different RF equipment.
I am using arduino uno in receiver section along with RA-02 LoRa module for 433Mhz(in ASIA). In the transmitter section, I am using arduino pro mini with RA-02 transceiver module. I wired all the pins for spi communication and decided to send 10 bytes of hex data from transmitter to receiver. The data was sent properly. But the TX pin led in arduino uno(which i had set as receiver ) constantly blinks. why is that so? Please reply.
Great video. It was all going great, and then all destroyed... How can I use arduino, that I already own instead of the modules you replaced? Can you use one transmitter to connect to several lora modules by changing the net id or or the other thing((:)? How many?
sir , is it possible to Receive 6 different data (coming from 6 different Transmitter Lora simultaneously ) received by single Lora receiver ( i.e. Many Transmitter , one Receiver) please suggest me sir
I'll take my commission for the copyrite of the "unique wabbit" joke now... You got that from my comment on the motion detector light thingie, didnt you. :D I'm amazed it worked that good with those little helical antennae...I never had great luck with those. There are a bunch of those ESP32's with the LORA built right in too, but I don't think I've ever seen that model. Thanks for doing a video on one of my favorite subjects! I have a whole home automation system built around those things - love them. You should do more. :) If you want to actually utilize them, let me know and I can give you some good links for the RFM69 + RFM95 types. I helped code some gateways and end nodes for them.
Hello, great videos! I'm doing a project using 2 arduinos with voltage dividers and 2 reyax modules. The TX arduino has a potentiometer, and the RX arduino has an OLED. I want to be able to read the analog voltage 0-1024 from the TX arduino on the OLED display on the RX arduino. But I'm having a hard time with code. I would assume it's pretty simple as compared with blinking an LED. My variable name on the TX arduino for the analog read is "readValue". The AT command im using for sending out the data is "AT+send=2,1,readValue. Is this the correct way to send data? Also my RX arduino isnt reading anything on the serial port except "0,1,1,1,1,1,1,1,1,1............." I'm very frustrated with this. Anyways again great videos, and if you got any advice for me, it would be greatly appreciated. Thanks!
Thanks sir for previous reply sir I'm doing a project in which I have 1 LoRa transmitter and 4 Lora Receiver . I want to communicate with any particular receiver But only one at a time ( As i want) That Receiving system should work according to my wish So , please suggest me that How can i make this possible sir Its solution is very very important to me Please suggest
Does it list the power the transmitter is at? I'm wondering if this is more power efficient than WiFi (which is a bit power hungry). Funny u mention the batt pwr sup dropping bc not enough current was getting drawn. I figured that out with a few Arduino projects and some research!
yes, much better than wifi. It's why these are great for battery home automation nodes. I have a whole system on RFM69 + RFM95's...they last months to a year on batteries.
Additional word of caution - some people mentioned running them from the 3.3v regulator of the Arduino. Normally it's a bad idea as it does not have power enough for the peak transmission levels, and causes unreliable behavior. Additionally, the RFM69+95 call for a set of caps 1pf 10nf in the reference design for noise. I don't know about these, but always wise to look over the datasheet as Paul did before use and check both points.
Great job Paul, although I have no idea what a Lora does, but nice to go out ‘n about in your ‘hood and excellent choice on the BP, my goto as well! ... 👍🏻 🐍
Lora is just an acronym for "long range." For this example, he set up a device to transmit a signal that told another device to repeatedly cycle an LED. He traveled about a mile away from the transmitter in his house and the receiver in his car was able to receive the signal resulting in the LED cycling on-off over and over again. Hope this helps. :)
Eddie - Thanks, appreciate the thoughtful feedback Eddie. I did gather some detail from Paul’s clear video, but aside from pulsing an LED, even from the BP station, I am sure it probably does a little more? I guess not being into transmitting of that nature I am ignorant of the capabilities of such devices... 🤔 🐍
I assume it could do more as well. In this example, flashing an LED was enough to show that the receiver could receive instruction from the transmitter over a long distance. It would be cool to see it transmit more complex functions like displaying "Hello, I'm here." on an oLED display. Or, have it set up so that the home device transmits "1" and the roaming device displays "1" then transmits "2" and the home device displays "2" and sends "3" ... the cycle continues.
sir does LoRa works with INTERNET or Without Internet , please suggest also suggest me any device (wireless protocols) with the help of which i can communicate up to 6 km , without using INTERNET
Anyone have issues with the reliability? I bought a couple modules and have been testing them. The ones I purchased off ebay off drop packets 80% of the time. 20% of the time it works just fine. My led flashes but its so random. I even tried changing frequencies, and still have the same issue. Anyone have any suggestions on how to make the more reliable? In my tests they are only 15 , 25, and 100 feet apart, and it didn't make a difference. On another note, this is an amazing channel. Keep up the great work!
of course. 'tame way. :) Pauls demo is absolutely terriiffic, but understand it's a proof of concept. There are libraries that exist for it that make that easier + do the error checking + ack's. Check the radiohead libraries...I think they work with that. I use them for RFM69 + RFM95...I know they are good for that and have you some good examples...
Great video with one exception. LoRa in the United States is restricted to the 915MHz ISM band only. Your video shows a frequency of 865MHz which is not allowed by the FCC for any ISM transmissions including LoRa. Don't get caught or you will pay a hefty fine.
Stumbled across this video from MickMake as a YT recommended. I would of liked to watch these two videos, but I just can't get past the sound cutting in/out as you talk. Please just set the mic to always on, and not "on while talking". I don't mind the little bit of hum in the background. But when everything comes/goes, it makes it disorientating to me :(
I live near an airport and military base. Will this device interfere with them at all? I don't want Big Brother dropping the hammer on me, lol. Also, I'm thinking of learning a programming language. Would Python be a good first language or would you recommend something else for baby's-first-programming-language?
If they can sell it legally, then you won't have the hammer dropped. However, having worked with the military, if they run jamming at the base near you for training you might find a problem. I have been on a base during training and lost 2.4G for a while.
Hi Eddie. FYI, 915 mhz in the USA is called ISM - Industry Science and Medical. It's especially meant for these things. My slight concern is Paul mentions ~890mhz, I dont think you can use that. 915 is the proper one in the USA. Also, 350->450 is ok, but for "bursts" only - so no LORA for this frequency. Make sure you select the frequency properly. Python is a great language to learn. It's an interpreted language, so it's debug "on the fly" so kind of easy, fun, modern,and widely adopted. For microcontrollers, C++ is best. Do not waste your time with LUA, it's dying I dont care what anyone says. Credit where credit is due-it is fun though, but Python would be more rewarding. To be more specific about why I recommended these - I'm a senior programmer with 20 yrs experience. I recommend these because for working with projects like you are going to want to start with, you will find these 2 are going to have the greatest amount of public support in the form of library. But please dont be a script kiddie and learn the datasheets like Paul taught you!
Dude... this code doesn't work. Just copied your whole setup, and not only is there issues with the code compiling, you don't even use the right serial code. Really sad to see how you faked this...
Wow ! These modules are nice, and you video too ! Thanks :) Do you think that I could send like 300 octets per seconds for a long range easily ? Like 1 kilometer?? Thanks :D
I think I will propose it at work. We are doing an IOT electric car recharge station prototype. WANing it across the city would be a game changer if it works. BT is for mobile Conn for payment obviously.
I know you got your for free but looking at the price of $19.00 each on Amazon I am going to pass as to use two it will cost me $40.0 plus post to the UK So thanks for the videos but not for me
Hey you are obviously knowledgeable about things, but then you keep referring to a bit rate (bps) as "baud rate" (it is NOT the same thing). Please never say baud rate again (it is not relevant in this context). Thank you.
That's not in line with what I was taught - "In telecommunication and electronics, baud is a common measure of the speed of communication over a data channel. Technically speaking, it is the unit for symbol rate or modulation rate in symbols per second or pulses per second." So bauds were (are) still basic units of data, could just as easily be waves of a flag or flashes of a torch - still bits of data, 1 or more pulse - so what's your problem? Its as accurate as any old fogey is likely to get.
Not they are NOT equivalent. Since you are curious, why not google baud vs bit rate to find that baud rate is: "the number of signal or symbol changes that occur per second. A symbol is one of several voltage, frequency, or phase changes." The numerical values (not the meaning) were the same EONS ago when the bit rates were extremely slow (
When communicating with the Reyax module serially over the UART (RS2332) the datastream is one bit per symbol so "Baud" or" bps" can be used to describe the data rate. The faster dial up modems (14.4k, 56k ) used multiple bits per symbol so they would not exceed the bandwidth of the telephone line. Their speed was indicated with "bps" and using "Baud" would be incorrect. In this case he is correct in using the term "Baud". If you are not convinced download the RYLR896 data sheet and look at the AT+IPR command.

“Not going to that one, no reason I just don’t like that one” classic lol glad to know I’m not the only one holding gas station grudges
Thanks! I was under the impression that to use Lora, I would need at least 5 pages of code, but you can really make things simple.
Well done man, it took me 100 videos to find this!! And you explain things so simply... keep up the great vids

You connect rst pin to d13. Lora is not declared in the code this D13 pin is also not specified. What is the purpose of RST pin?
@~3:30 you are communicating with the device when you send it the AT+RESET command. Why then would you need to send it the baud rate command after? If the baud rate were different (than 9600) on power up, then it would not recognize the RESET. I think the baud rate command would be only for changing baud rate from default.
Thanks for this, just as well I didn't order the parts for the project till I had seen your second video! LOL
Hi. In the transmitter code, shown in the video, I think

Dumb question, can't you use the 3.3 output pin one the uno to power the lora board?
Am wondering the same thing! Arduino supports it, why not use it? :)
I misunderstood what he was saying . The data bus is 5v. You'd have to get an Arduino that does 3.4 volts. Like the Spark fun Pro Micro from China which ain't cheep.
Why not just use each of the Arduinos 3.3v pins?
Thank you! I can't wait to order the parts. 'Glad I became familiar with the Arduino a month ago.

Thank you. Just now i was able to transmit distance of 16.29 km or 10.1 miles
Is there any chance for you to send the code to me , please i would be verry happy
Was that an antenna upgrade?
Maybe you'd like to share your configuration or are you just trying to be the best?
Hi sir, Im curious on how the the transmitter send the H and L without printing the "AT+SEND". How does this work? Thank you sir
Do the arduinos not have a 3.3v power out that you could use? I ask because i am trying to do the same im just wondering if i could use the 3.3v out safely
Why didn't you just connect the LoRa to the 3.3v power on the UNO? Is there something else going on that wasn't shown?
Good explanation. I trust you didn't simply upload an LED blink program on the receiver. Wish the receiver was doing something else to illustrate communication with the transmitter.
if you use gate and limiter in your audio it needsx to be turn down because it cutting u off at times to quick and also do u need a pop filter i got one if u need one i will send u sounds like your gate is set to close to fast etc
No one seems to observe that these things use spread spectrum technology. They also are quite pricey -- seem to be for military and such. This does not appear to be targeted towards IoT or hobby.
I'd appreciate a file containing the code for the LoRa modules. Would save a lot of suffering from trying to type it in from a screen shot.
Thank you for the clear explanation and demo.
Could someone please explain me about the voltage dilema? I didn't understand why he had to change the components

Stumbled across this video from MickMake as a YT recommended. I would of liked to watch these two videos, but I just can't get past the sound cutting in/out as you talk. Please just set the mic to always on, and not "on while talking". I don't mind the little bit of hum in the background. But when everything comes/goes, it makes it disorientating to me :(
Ok
Great, good job
Seems this module is not available anymore and it just continued 😢
You can still get them only you have to order 10 at once. ebay.us/Lrhvce
I live near an airport and military base. Will this device interfere with them at all? I don't want Big Brother dropping the hammer on me, lol.
Also, I'm thinking of learning a programming language. Would Python be a good first language or would you recommend something else for baby's-first-programming-language?
If they can sell it legally, then you won't have the hammer dropped. However, having worked with the military, if they run jamming at the base near you for training you might find a problem. I have been on a base during training and lost 2.4G for a while.
Hi Eddie. FYI, 915 mhz in the USA is called ISM - Industry Science and Medical. It's especially meant for these things. My slight concern is Paul mentions ~890mhz, I dont think you can use that. 915 is the proper one in the USA. Also, 350->450 is ok, but for "bursts" only - so no LORA for this frequency. Make sure you select the frequency properly.
Python is a great language to learn. It's an interpreted language, so it's debug "on the fly" so kind of easy, fun, modern,and widely adopted. For microcontrollers, C++ is best. Do not waste your time with LUA, it's dying I dont care what anyone says. Credit where credit is due-it is fun though, but Python would be more rewarding. To be more specific about why I recommended these - I'm a senior programmer with 20 yrs experience. I recommend these because for working with projects like you are going to want to start with, you will find these 2 are going to have the greatest amount of public support in the form of library. But please dont be a script kiddie and learn the datasheets like Paul taught you!
How do you catch a tame rabbit?
Idk
tame way...lol. The same way as you catch a unique rabbit...uneek up on it.
Dude... this code doesn't work. Just copied your whole setup, and not only is there issues with the code compiling, you don't even use the right serial code. Really sad to see how you faked this...
Good work
8.685 MHz is standard for LORA in neither US nor EU
Wow ! These modules are nice, and you video too ! Thanks :)
Do you think that I could send like 300 octets per seconds for a long range easily ? Like 1 kilometer?? Thanks :D
Excelente, gracias por compartir
Very cool
If I used a Lora and a Bluetooth module in the same machine would they interfere with one another?
Rf is not my specialty, but Lora is 800-900 MHz and BT is 2.4GHz so i would say no.
I think I will propose it at work. We are doing an IOT electric car recharge station prototype. WANing it across the city would be a game changer if it works. BT is for mobile Conn for payment obviously.
Hi friend, can you share the codes of arduino?
Rodolfo Vieira same, need the codes
I know you got your for free but looking at the price of $19.00 each on Amazon I am going to pass as to use two it will cost me $40.0 plus post to the UK So thanks for the videos but not for me
neat
Why not take down the first part so people like me don't waste our hard earned cash buying the parts you suggested then changed your mind.
Hey you are obviously knowledgeable about things, but then you keep referring to a bit rate (bps) as "baud rate" (it is NOT the same thing). Please never say baud rate again (it is not relevant in this context). Thank you.
That's not in line with what I was taught -
"In telecommunication and electronics, baud is a common measure of the speed of communication over a data channel. Technically speaking, it is the unit for symbol rate or modulation rate in symbols per second or pulses per second."
So bauds were (are) still basic units of data, could just as easily be waves of a flag or flashes of a torch - still bits of data, 1 or more pulse - so what's your problem? Its as accurate as any old fogey is likely to get.
Not they are NOT equivalent. Since you are curious, why not google baud vs bit rate to find that baud rate is: "the number of signal or symbol changes that occur per second. A symbol is one of several voltage, frequency, or phase changes." The numerical values (not the meaning) were the same EONS ago when the bit rates were extremely slow (
When communicating with the Reyax module serially over the UART (RS2332) the datastream is one bit per symbol so "Baud" or" bps" can be used to describe the data rate. The faster dial up modems (14.4k, 56k ) used multiple bits per symbol so they would not exceed the bandwidth of the telephone line. Their speed was indicated with "bps" and using "Baud" would be incorrect. In this case he is correct in using the term "Baud". If you are not convinced download the RYLR896 data sheet and look at the AT+IPR command.
Are you in the telecom police? K9 is right about Bits & Bauds.
