I've done a lot of youtube research about Lora gateways/nodes and your videos are, by far, the best Andreas. Thank you for your help!
Glad to read that. Thanks!
Love all of your videos.
Very straight forward and easy to understand.
Thank you for your time.
Thank you for your nice words!
Thanks again Andreas. You are still half a step (read: half a postal cycle from Asia) ahead of me and some RF95W modules I ordered. Just perfect!
+Garry Keogh And maybe till then, my last gateway build will also be ready...
God bless you Andreas. Please do more videos about Lora...
Will do
Really don't know why they post (not like) this video. All profesional well explain. And motivate me to create a LoRA gateway in my city, Tijuana, Baja California México. Waiting fir my RPI hat !! 5 stars video
Thank you!
did you made it? :-)
¿Y qué pasó, sí lo hiciste?
Hola. Pudiste armarlo?
Useful & interesting. Thank you. It reminds me of the early days of ham packet radio.
+Art Becker You are right. The advantage here is, that it is on a open band and you do not need a license (even if this would not be a problem for the two of us)
Thanks for the wonderful video.
What's the range I should expect with the dragino hat?
The same as all other boards.
Great series. Thank you. Currently setting up a local GW until the iC880A-SPI is back in stock.
I have an old Pi2 I have no use for and no GW in the area.
Sounds great!
Looks like the way to go is the RAK2247. The model mentioned in this video is probably out of date as the video was recorded in 2017.
Total comes in at 145 Euros. Nice
EDIT: Maybe it was another video where you showed the RAK
sorry for another question, but in the github repo it says that it is deprecated, and the code is not up-to-date to use on the TTN. do you know any other ones? or this still works? thank you!
Another great video mate.
+Chris B Thanks!
Great Video, Great effort
Great videos Andreas!
I'm using the exact same hardware, however I'm attempting to build it as a simple node. Any wiring or setup tips?
I think the wiring should be similar if you use the same LoRa module
Hello Andreas
Verry good Video, thanks! I have one Question. Did you also do a NODE with the same Lora/GPS HAT + RaspberryPi (not a Gateway show in this Video) and TTN connectivity?
I do not remember that I built a node with an RPi. Would not make a lot of sense for me because LoRa nodes ae low power and the RPI not exactly...
Great videos Andreas!but if i will use the gps in lora hut waht will i add ?
I never used the GPS so I do not know.
Thank you Andreas for the great videos, I really do like them. I have two questions regarding the Dragino LoraHat.reading the documentation, the blue led light up when the gateway is receiving packets, mine after is connected, the blue led turns on and stays on forever. another thing, it alway disconnect by itself even the dragino code is running on the raspberry pi, do you have any idea how to fix this. thanks again.
I do no more remember these details. And currently, I do not use this shield anymore. I use the RFM95 boards and ESP chips
Hi andreas. Good video. Maybe it is a good idea to talk about the ttn fair access policy. About what it is en what it is for.
I talked about it in one of my LoRa videos. But so far, it is not enforced
hello, Iam testing lora communication by using RN2483 PICTAIL LoRa module, i bought two of those lora modules can they communicate directly without any gateway in between? please reply ASAP , thankyou in advance
Hello Andreas! Thanks you for providing such good videos! I have project in mind, and I need to transmit data inside a filled grain bin, which technology would you suggest? Max distance would be around 15m, small packets around 8bytes every minute. Power consumption is a concern, running out of a 2000mAh 3.7V battery, lasting for at least 1 year. Is LoRa suitable?
I definitively would give LoRa a try. Just pay attention that you do not have too much metal between the sender and the receiver.
great video! thanks! i tried it myself and its working but. when i close my ssh session the raspberry pi software stops working. tried putting the the sartup command in corntab wihout any luck. do you or have a suggestion on how to solve that issue?
I am no Raspberry specialist. So, you have to ask somebody else.
Thank you for your videos! I´m a big fan of you please continue the good work, I have a question is possible to connect more than one RFM95 to the raspberry?
Yes. The dragino shield does that.
@@AndreasSpiess so it's possible to create a PCB with four to have 4 channels ?
No. You need a real gateway if you want more than 1 channel.
Hello Andreas, very nice video!
Could I just ask you a question? There is a "frequency mark" on the back of every RFM95 module for 915, 868, 433, or 315 MHz. But you can set the carrier frequency in the module´s registers, so why is here this mark, if you can choose and set frequency that you want.
Because of the filters on the board.
@@AndreasSpiess Oh, I see. Thanks a lot! :)
Thanks for the tutorial, it's being very useful.
1) in Traffic Gateway, I'm getting payload from several DevAddr, but next to me there is only my mote (dragino + arduino).
2) in the Traffic Gateway, I can see the packets arriving, but in the Application Data it does not show anything.
Could you tell me what that might be?
I am no TTN specialist. Maybe you go to the TTN forum for debugging help. There you find the real "cracks"
Hi Andreas, thanks for the great explanation. I have a question. Ispossible to create a gateway like this using an arduino board instead of Raspberry Pi? Thanks!
No. You need an internet connection. Maybe you look at my LoRa playlist where you find other gateways.
But using an additional ESP8266 module with wifi access connected to Arduino, I can have the connection to internet. In this case, I think should work.In any case, your recommendation is to use another platform instead of Arduino? Thanks!
very intresting... but there is a difference between rfm95 and rfm95W? because on aliexpress i only find rfm95. thanks. great video!
I do not think, there is a difference. In the data sheet, the manufacturer puts the W in parenthesis.
You probably know this by now but the W indicates CE/FCC certification as per www.hoperf.com/faqs/410.html
PS. Thoroughly enjoying your channel by the way, enthusiastically ordered a Dragino hat yesterday :)
Great Tutorial! Does anyone know if it is possible to do this with a 433 MHz module? The choice of frequency is transparent to TTN, isn't it? Or do you need to change something?
Maybe you ask this question in the TTN forum?
Hey. Loved the video, i was just looking at this as an alternative before you posted the video. Any tips on the cheapest LoRa module/shield to use with a esp8266 that's compatible with this setup (in europe). And while im writing i gotta say thanks for a ton of videos you post, really helpful =)
I plan to build a gateway with an ESP8266 and a RFM95W in the near future
Hi, Andreas :) I'm very interesting with this video. But, I want to know about
can lorawan gateway created like this load more than one node? I plan to create it, but I really dont know about it and I cannot find the reference yet.
Such a gateway can serve many nodes. Depending on the frequency the nodes send data and how long they need for transmission.
hi, thanks for the great explanation, but i have a question, what if i want to create a private lora network without connecting to ttn, is it possible?
Yes, but complicated.
Thanks you Andreas for this great video! I started a single channel Lora gateway to get my feets wet with The Things Network. Do you know why the single channel packet forwarder (from the Charles Hallard fork) software works on my rpi 2 but not the rpi 4? I suspect wiringpi but I can't move forward...
Wiringpi will no more be advanced by the developer and I do not know if it was ported to buster.
@@AndreasSpiess It works now on the rpi4 with wiringpi updated to v2.52 : wiringpi.com/wiringpi-updated-to-2-52-for-the-raspberry-pi-4b/ . Although I understand what he might feel, it is sad that the main developer is fed up with trolls...
@@etmoimeme great, you fixed my issue :). Thx a lot!!!
Thanks for your video, always.
By the way, you said it can only support one channel.
Does that mean it(Dragino hat_868MHz) cannot communicate with another dragino shield_433MHz?
Both devices have to use the same frequency.
@@AndreasSpiess my both devices are using 433 mhz .how could i establish the communication between the node and the gateway through ttn or is there any other way as ttn doesnt support 433mhz
Dear Andreas,
many thanks for the great tutorial. I followed all the steps on your video on the same hardware as you had. Unfortunately the status on the TTN remains "disconnected". Also no errors whatsoever are reported on the debug console. Is there a way for more extended debugging? Also can the IPv6 "Lite" prevent the gateway from connecting in some way?
Beste Grüße
Georgi
This is an old video and if I remember right, TTN changed its IP addresses. Maybe you check it?
hey @seeman8484 i have exactly same problem with you , i have same hardware but status on TTN still "disconnected" . have you found solution yet ? i have change IP address to au915.thethings.meshed.com.au base on www.thethingsnetwork.org/docs/gateways/packet-forwarder/semtech-udp/#connect-a-gateway_server-addresses
and change freq to 915Mhz . @Andreas Spiess
Hi Andreas, i'd like to ask you something. If i use the lora dragino shield 868M for the node side, should i use lora dragino hat with the same freq (868M) as the lora dragino shield on the gateway side? Nice vid as always btw
If devices need to talk to each other they have to use the same frequency
Andreas Spiess thanks for the answer Andreas :) it helps a lot
Hi, can you please tell me how to set frequency to 865Mhz using "single_chan_pkt_fwd" library for raspberry pi with lora hat
Thanks Andreas for the great videos. I really appreciate your current efforts regarding consumer implementation of LoRa and LoRaWAN. Especially the slide titled differences between gateways.
Do you have a donation link, to support your work?
-A permanent subsciber
Yes, I have a Patreon link in the newer videos. Thank you for your support!
Reading the various threads on the single channel LoRa gateway, appears TTN prefers to NOT support single channel. They recommend deploying multi-channel versions, though they may make some accommodation in time.
So, here's the question: Is it possible to adapt the "cheap" gateway to make it multi-channel capable?
You got the answer?
Could I use it for home automation without connecting/registering to the 'cloud' (TTN)? Would I have to set up some sort of network server?
Maybe you watch my LoRa videos beginning with the introduction. There your questions will be answered, I think.
Hello Andreas,
Thanks for the Video. What is the reason that it does not run on a Raspberry 4? It worked on a RPi3+.
It did not exist back then ;-)
When I follow the directions for cloning the github files in the instructions and try to open main.cpp in nano, the page is blank. In fact the read.me and the LICENSE docs in the single_chan_pkt_fwd directory are also blank. Obviously doing something wrong, but have no
idea what.
Hi! Are there any new development on the "cheap LoRa gateway" frontier regarding multi-channel operation? is it still not possible to let frequency hopping do its job?
I did not follow this route. Just ordered another gateway from RAK for 130$. The prices are coming down...
RAK looks promising-- looking forward for your review
Hi Andreas, I've been thinking about putting some sort of "car alarm" system together. I would work with a notification system via cellular. Except that I often park my car in remote area while I go fishing. These areas do not have cellular coverage at all. So I am thinking that LoRa might be a good fit?
Unless there's something better out there for this specific use case? I am just expecting to receive message alerts with the sensors being triggered by the security system. (No need for large amount of data like video or images)
I made some videos about the capabilities of LoRa. So you have to decide if it fits your use case. Draw once the whole system end-to-end on a sheet of paper. Then you see al the problems you have to solve and where LoRa fits in.
Hi Andreas,
Do you think we will be able to use this kind of Gateways in a professional application ? and what can we do or change to make this Gateway a multi-channel one, and can i use it with another server like wso2 iot ? thanks in advance !!
If you watch all my LoRa videos, you see, that many Telcos strarted to build networks based on this standard. So, I assume, it is good enough...
The Single channel, however, is just to experiment. It does not fulfill the full standard.
I already have a Pi set up for Home Assistant. Can this be installed along side of HA or does it need a dedicated board to run?
I do not know Home Assistant so I cannot answer the question.
Hi Andreas,
First of all, Thank you for all great videos.
I have one question. Why it has only single channel and supports only 1 spreading factor? Is it because of hardware limitation or software limitation?
It is a hardware limitation of the transceiver. You find 8 channel gateways on this channel. But they are 10 times more expensive.
Thank you @@AndreasSpiess for quick reply
@@AndreasSpiess Hi Andreas, thanks for your excellent video.
This board only works on 1 spreading factor?
Hey andres, what are ttn alternative networks that work with lora ? Are those work with this gateways
Thanks
+iboy I do not know of another public network with LoRa. You can build your own network and connect it to the internet. But I have never done it
You can build your own with loraserver.io
Hello. In our area, there is no existing LoRa gateway. I am also planning to develop a LoRa Node that utilizes the RFM95W operating at 915MHz (Asia). Does this mean that this single-channel gateway will work well? Thank you.
It will work as I said in this video. 915 is mainly in the US. Most Asian countries use 433MHz
Are you planning to do overview of lora gateways tech up to date?
I have no such plans for the moment. But you never know on this channel ;-)
@@AndreasSpiess thank you! You are a great man
Hello, thanks for the video. I was able to build a single channel gateway as demonstrated. I have two more dragino lora hat shields for raspi 3. Can you show how to build a single channel (if possible) node using the lora hat and raspi 3. Thanks.
You are welcome! Nodes usually are simple and low power devices. So, I cannot imagine to use a Raspi for such a purpose.
Andreas Spiess yes Sir you are right but as I said I already purchased 3 shields and 3 raspberry pi 3 for this project. The lmicpi example does not always work (looking at the ttn data seems to have worked at times) and most of the time gives radio.c error at line 630 and the message that starts with OhOh... any pointers to make this work will be highly appreciated. Thank you.
As I wrote. I have no knowledge about LoRa nodes on Raspberry. Maybe you ask your questions in the TTN forum. Maybe you find somebody which already has this know-how.
Thank you Andreas.
Andreas, Do you know what the frequencies for LoRa in the US are? (915 MHz band)
Also, will the gateway support the new SX1280 on 2.4 GHz?
1. LoRa is on 915 in the US
2. The gateways only support one frequency range.
I see the limitation. There is no LoRa hat for 2.4 GHz, even though there's SX1280 Modules available.
interesting video ,, great ..
hi sir
i have a related research about Lora ,,
what is the size of the frame in the LoRa ? it use protocol LoRaWAN and work on the 2nd layer in OSI 7 model .. thx
I never looked inside the LoRa protocol itself. So, I do not know.
thank you for respon sir ,, have a nice day
Excellent video, I was wondering what's special about that HAT apart from the adaptability for the raspberry? As shown in minute 1:45 I see that it is possible to make the Gateway only using the raspberry with a LoRa module, in my case I have the LORA 433MHz E220-400T30D - LLCC68... am i right?
I am not sure if TTN still supports 1 channel gateways. Most people now use commercial 8 channel gateways.
Hey Andreas, I have problem 3:51 to 4:09, after registering my gateway on TTN, the status is "not connected". any solution? thanks for your great videos..
Maybe you ask somebody on TTN. There is also a newer version of the gateway software available (see other comment)
Thanks for video. Can you explain hot do connect and manipulate nodes with red.node?
You can connect node red to LoRaWAN. I think, I showed it in one of my videos.
Andreas Spiess thanks, I will look for video:)
Hey Andreas,
Any chance of showing how to setup the lorawan pi hat as a node device and send data to TTN? I bought one a few weeks back but am struggling to find any information on how to get it to work.
I do not see an RPI as a good idea for a LoRa node. LoRa is low power. The Raspberry not really...
@@AndreasSpiess No worries, its all subjective though, as it depends what you're using your rpi to do. To send some industrial points your monitoring would be extremely handy. As the esp devices don't like to talk modbus.
What kind of range can you get using this cheap gateway and the button sensor ?
Which button sensor do you mean? You find a few videos in my LoRa playlist about range
Sir, Should I use the same transceiver for both gateway and nodes?
Yes. The 1 channel gateway uses the same module
Andreas, just got my RasPi LoRa Hat in and was trying to follow your instructions. Sorry but I am new to the Pi and LoRa but want to get the LoRa up and running to start testing. I got the SPI enabled but got lost your Step 4. Typed in at the command prompt and got up a GNY nana screen and not sure what to do from there to add the rest if the information.
You TH-cam posts have been extremely helpful.

Comfort, Texas
Just read Jeff Davis' comment below. The Raspi/Lora hat gateways do no more work. I hope, they will find a solution.
Just ordered a LoPy-PyCom board. Hope to have better luck with it. It already has a smart phone drag and drop type interface. Will have to check out issues with a single channel. I only need a single channel for this application. Gate Access to a facility where my customers only to access the gateway.
Thanks for the video Andreas :) What would be the downsides of running my gateway in europe @ 433mhz? If I'm making my nodes to that specific gateway too and dont have much of anything else near me to rely on either? Will I conflict with any regulation or will Lora circle hate me much for it or something? PS. What does it mean that no downlink, does it mean I can only receive and not send any information?
+gelisob I do not know about 433 because it makes no sense for me. No downlink means, you cannot send messages back to your sensors.
Do you have any idea how to build an electric smart meter using lora? I'll follow these steps to interface Rpi and Lora and building the gateway. After that, I'll need help. Thanks!
I never did that. But maybe you divide the problem into several smaller projects and go for one after the other?
Would a Gateway like this still have the same range and reliability is the first gateway?
Yes. But it only has one channel and only one SF at one time. The "big" gateways have 8 parallel channels and can adapt to all SF on the fly.
Hey Andreas, could you show how you made those applications on thethings website? I'm trying to find a way of decoding what my LoRa node is sending to this newly built gateway and I can see things changing on my Pi every time a message is sent from the node, but I don't know what to do with the data. Could you help out in any way?
Maybe you watch my other videos about LoRa. Especially the ones with Node-Red. There you should find some info.
@@AndreasSpiess Sadly, I'm very stuck. The only video of yours that I've found that is on this topic was the one where you did the TTN Tracker. I couldn't find any other myself. Unfortunately, the code on that application is far too complex for me to understand and extract what I need. I'm after a very simple tutorial of connecting a simple LoRa node, to a Dragino+Pi Gateway thats already on thethingsnetwork and show information gathered by the LoRa device (in this case a heltec esp32LoRa). Nothing on the internet seems to help, in simple terms. And everyone seems to be making gateways, but not the devices.
Do you know if it's possible to make a LoRa Node with this Dragino Shield? I'm intending to do so, but I barely find information about it.
It can be done. But most people use combined LoRa and MCU boards.
Hi andreas great tutorial thanks a lot!. I followed the same thing and used server1 "54.72.145.119" under TTN platform and port 1700 but i got stuck as i got the issue of unrecognized transceiver.. so could you suggest me how to solve this or is their any alternative to build single channel gateway using dragino lora shield V1.4.
Maybe you check out the newest software and addresses in the TTN forum (www.thethingsnetwork.org/forum/c/gateways/scg )
thanks for the reply . I have tried server 1 "13.76.168.68" which point to router.au.thethings.network but still i get the same issue. Is this as i am using v1.4 dragino lora shield or their is any error in server address . can we use the same ip as of europe as in india we are using the same 868MHz ?
Hey shwetal.. have you got a solution for the issue you faced?
You can at least try the European server address
Hey! thanks.. i got it running from the asian servers.. had to use nslookup to get the correct address..
Hello Andreas,
Reading the comment threads below, it seems RPi Single Channel Gateways are no longer supported by TTN since it does not have downlink capabilities.
I was actually about to begin the tutorial in this video. I have all the hardware requirements until I came across the comments and the forum at TTN below (from Jeff Davis')
So, one question, should I continue? Can you please suggest some alternatives? Thank you.
The issue seems to be resolved by now: www.thethingsnetwork.org/forum/t/resolved-some-single-channel-gateways-stopped-working/6529/18
Two days ago, I tried my gateway and it worked.
Great! Thank you so much :)
Hello Mr. Spiess and thank you for your videos,
at 7:51 you speak about disabling frequency hopping. For me it is unclear, where this has to be done. In the Sensor? Per downling message? Please help / thank you.
Roger
It has to be done in the sensor because the single-channel gateways only listen to one frequency.
This is an old video, and I am not sure if single-channel gateways still are supported by TTN.
@@AndreasSpiess Thank you.
Yes, they are still suported, and mine (done according your video) is working since approx. 2 weeks without problems.
According your answer ("that has to be done on the sensor"), the sensors have to come back to my lab, because a downlink can not be established with this gateway and there is no coverage from another gateway at my location of operation.
Greetings from Fricktal!
hello, is it possible to create a private network and recieve the packets from a node on the gateway? and how
Maybe you watch my LoRa one to one video. And you can copy all code from TTN and build your own network (if you have the time). It is open source.
@Andreas Spiess, can you please tell me if there is any modification to send data using 865-867MHz. In my country we have to use 865-867MHz
Maybe you watch my LoRa videos? In Europe, all use these frequencies
@@AndreasSpiess can you pls tell me which video number. Need to set it up for 865MHz
You are make, really great videos!
Thank you!
Hi Andreas,
Thanks for your work and introducing me to the world of LoRa.
I followed this tutorial using a RPI3 + Dragino Lora/GPS Hat. At first I was getting the 'Unrecognised Transceiver' error. However, I tried it with a RPI2 and it worked fine :)
However, now when I register my gateway with TTN, my status appears as 'not connected'. I've read on some forums that this is because my gateway is single channel, can you tell me if this is correct?***
Also, my next plan is to set up a node using your tutorial in #117. Do you think regardless of the 'not connected' issue above I willbe able to connect my node with gateway?
Thanks again for all your work!
*** Oh silly me, I just saw the pinned comment, apologies, I will try it now!
First, you have to solve the "not connected" issue. Otherwise, your node cannot connect through the gateway.
@@AndreasSpiess Thanks for the reply, yes I switched over to github.com/bokse001/dual_chan_pkt_fwd however, I'm having the same problems as Floris and Henry in Amin's pinned post...
Andreas, I'm facing a problem trying to find my Gateway ID, when i use the comand as in the screenshot on the video it says "Unrecognized transceiver". What is that and what should i do? Thank you
Maybe your wiring is not ok?
what protocol did you use in this project? and how many end-node devices can you connect to the gateway?
The loraWan protocol. Please watch all my LoRa videos for clarification
But in my acknowledge, with lorawan protocol, you can not create the communication between 2 sx127x.
Andreas Spiess, in your video, you said that lora protocol, but lora is the modulation, it's not a protocol
If you would have looked at the LoRaWAN specification you would have seen the first sentence: "This document describes the LoRaWAN™ network protocol which is optimized for battery-
3 powered end-devices that may be either mobile or mounted at a fixed location"
Hi, i have a question, why do u use Raspeberry for the gateway? I´ve watched many videos in internet about the "Gateway" and all of them use rasp or Dragino technology... is it for something special? i was thinking about using ESP32 maybe, but idk
Most current LoRa gateways use 8 channel chips and I do not know of an ESP32 software that supports this setup.
Edit: Search for "ESXP1302 LoRa Gateway" for a software
I'm trying use this for OTAA connect to my dragino shield but not success , is this possible using OTAA using this gateway
Maybe you go to the TTN forum. I never used OTAA
Bonjour. Merci pour vos videos. Je vois que le hat est toujours vendu : le recommandez vous toujours en 2022 ? est-ce stable ? combien de ''clients'' lora peut on gérer avec cette passerelle ? merci
Maybe you watch my newest LoRa video about the new V3 version of the TTN network?
Is there any significant advantage to using this method vs the $15 Wemos D1 Mini version (bearing in mind the price difference if you have to buy a Raspberry Pi?
There is no advantage. Unless you build a full blown multi channel gateway with the PPi
Andreas Spiess Thanks - I have a Wemos, so I'll start with that...
In your range video it was mentioned 20Watts output power. Did you mean 20dbm?
Yes. 20 watts in ISM bands would be illegal.
Can you advise how I can how I can you the Dragino Hat with the Arduino MKR WAN 1300?
I do not use this board. You have to connect the different pins of the Hat with the same pins of the MKR. Then it should work. Pay attention if the MKR runs on 3.3 volts.
Hello Andreas, congratulations!. I'm new at this. Can I make a gateway with an MKR 1300 and a Raspberry PI? If so, could you tell me how or guide me?
Maybe you can. I never tried.
@@AndreasSpiess Thanks!!
Can i ask what's the point of a gateway if it can only handle 1 channel? I mean if I have a handful of nodes they will probable crash with each other when 2 or more wants to send a message to the gateway.
Or am I missunderstanding some concepts?
Thank you very much for your videos, they are really useful
You are right, of course. But law only allows 1% ON time per node. So the chance of collisions is quite small. But they are allowed in this protocol
@@AndreasSpiess thanks for your answer!
With that 1% ON time are you refering to airtime? Because you can change that by changing the spreading factor and then making the chance of colission bigger right?
I will do some tests tho, thank you for your time I am doing my EE thesis with this topic!
Yes, on time or airtime. The SF influences how long the packet needs and how much it takes fron the airtime. Higher SF= less possible messages per time
Hi instructor, please let me know where we can find the server Ip address? For example, you have used #define SERVER1 "40.114.249.243" so which IP and where can I find it?
My second question, the packet forwarder is very old and is no longer supports the OTAA method. Is there any other latest packet forwarder that can support the OTAA method? Thanks for your constant efforts
Your router usually knows the IP addresses of all your devices. You have to google for your particular router.
Concerning packet forwarder: Maybe you watch my recent TTN V3 video?
@@AndreasSpiess Thanks for your response. Okay, but here we need to insert the IP Address of Raspberry pi or the router? I typed "ipconfig/all" and found this [IPv4 Address. . . . . . . . . . . : 192.168.1.194]], I am confused we need to put the router IP address or the Raspberry pi???
I watched TTN V3, however, I didn't find that you have used the packet forwarder that supports OTAA. Can you please refer me to the one? Thank you
What about the raspberry Pi Zero 2
Good choice as Gateway?
It should work. However this is an old video and you have to check availability of the software
Could you tell me the difference between hat and shield?
I'm using Dragino LoRa shield(v98) for arduino, but I want to use it with Raspberry pi if it is possible.
Usually additional boards are called shields if they fit an Arduino and hat if they fit a Raspberry
Thanks a lot sir !!
Is the single channel limitation from hardware or software?
The LoRa HW is either single or multi channel
Hi andreas,
Is it possible to build uplink and downlink LORAWAN with less cost and why can't we develop downlink using arduino and lora. can we include 2 different channel, 2 SF to obtain downlink
You do not need 2 channels for downlink, it happens all on the same channel. I think, I will build another single channel gateway which should be able to downlink.
yeah i will be highly appreciated if i got downlink code. Thanks for reply andreas
Hi! I am putting together the same project to do some tests but I have the 915MHz RFM95W, does that rpi software work the same for my lora module in 915mhz? If you have an example, can you send it to me? Thank you!. Greetings, very good project.
You chose the frequency in your sketch.
Can you create a video on how to set up as a node?
Maybe you browse through my LoRa playlist?
I have a question, i have seen before that everyone who uses a gateway for LoRa sends the data to the things network, but i can create my own server to send the data there? or i have to use strictly the things network?
You can create your own server if you want.
@@AndreasSpiess thankss
Hi, nice video but may I ask if this is LoRa or LoRaWan :)
I wanted to use ttgo or esp32 with meshtastic to set up a lora mesh network and transmit and track company vehicles. Any video on how to do this and how to view the trucks on my website without coding as my site is on WordPress.
Many thanks in advance
Christopher
This is LoRaWAN (The Things Network). I never did a video about car tracking.
@AndreasSpiess Thank you for replying and your answer.
Would you consider doing a video on how to track vehicles and how to use meshtastic lora and get the data onto a pc screen for observation and or back to a server/website.
I'd like to be able to add it to my WordPress site if possible.
Question If I don't care for LoRaWAN or getting on-line with my sensor data, what are other limiting factors of Single Channel LoRa gateway? Is the communication speed limited between sensors and such gateway? Is it difficult to find LoRa nodes which support to be configured in single channel mode?
Single channel gateways are also LoRaWAN gateways. If you do not want to use LoRaWAN you can watch my video concerning LoRa point-to-point
@@AndreasSpiess thanks, but can LoRa nodes also talk to each other, if I do not follow LoRaWAN protocol? And built my own private net
Would you share how to use LoRa Bee and ESP8266 or Arduino Nuno, please...?
Lorabee is just an RFM95 module with pins and an antenna connector.
@@AndreasSpiess Thank you...I solved it :)

Hello Andreas..
This still works?
Im trying to find a server for the dragino shield but i can't find one.
I do not know. There is a cheaper way for a single channel gateway: You can use an ESP8266 instead of a Raspberry Pi. I also made a video about it.
Want to ask if the gateway is built with Raspberry Pi, can it recieve data from a (arduino+LoRa) node?
Yes, they can.
Hello Andreas i want to build a communication between ESP32 and Raspberry Pi using Lora did you have any experience regarding this?
Most TTN gateways use a Raspberry. So there is communication between an ESP32 and a Pi. However, without LoRaWAN I am not sure you find LoRa software for the Pi. So you have to write your own.
@@AndreasSpiess Thank you very much Andreas for your reply i am suceed building LoRa communication between Raspberry Pi and ESP32 There is one library pyLora for the Pi i used for the communication
I wish i could afford setting up something like this were I live, I belie in this technology. this has so many use cases
Maybe somebody already did it? Did you check the TTN or Helium coverage map?
Is that working with Raspberry 1 B+? or only with 2 and 3? thanks in advance
I assume it works with them, however I did not test
Andreas Spiess thank you!!! I will test it and get back to you!
How can we create a LoRa gateway without connecting to TTN? Do you have a tutorial on this?
No. I only have one for LoRa direct connections
Thank you. i have a plobleme ,i don't know how i connect raspbarry pi on reseau lora ? plz can you help me
I made many videos about LoRa.
@@AndreasSpiess ok Thank you
@@aminaboujnen7378 maybe yo have rpi 4?
hi! is it possible to transmit video over Lora channel ?
No. Not enough capacity
Dear Andreas, How can I check received data in Raspberry Pi from LX Terminal? Thanks for your support. Grettings from Medellin Colombia
This is an old video. So I do not remember well. I think you should see it in the log of the running packet forwarder.
Hi! Up to how many nodes this gateway can support? Thanks
It depends on how often the nodes transmit and for how long. Maybe 10 nodes should work ok.
@@AndreasSpiess thank you..
