Multiple Lora clients with a Server communication
HTML-код
- Опубликовано: 23 авг 2024
- Communicate between many LORA clients to a server sometimes becomes tricky. Because if we just send the data without caring about the delay or sequence. They can be really messy. So how to make sure that all data are sent and organized? Watch this video till the end!

Terima Kasih mas..., semoga mas nya dapat pahala berlipat ganda dengan sharing ilmu ini..., Aamiin...
Finally multi node tutorial. Thanks. Please do more videos on LORA
Thanks!
I know this was a few years ago, but I love this.
Instead of the message being sent, I assume I can have that “message” sent if I had a button and the Node registered the button press?
Excellent Man!! I was searching about how to make a string with differents transeivers, thanks
Thanks! Don't forget to subscribe. I really apreciate 😀
Awal nemu Reyax LoRa seneng banget karena mudah sekali untuk mengkonfigurasi node dan mudah sekali untuk mengirimkaan data ke node tertentu apakah client atau server. Namun setelah mengetahui harganya tidak ekonomis untuk dikomersilkan, terpaksa mencari alternatif LoRa yang lebih murah.
Thanks! help me a lot with my communication problem between LORAS.
Hi, great tutorial. where did you get the RH_RF95 lib for arduino?
Thanks
is it possible to make a mesh network with 4 LoRa nodes?.... and all the nodes communicating with each other with LoRa RMF 96?
you don't have to put (millis() - millisBefore > 1000) since it falls under the "else if" condition, it's automatically greater than or equal to 1000 if the first condition wasn't met, also what happens if (millis() - millisBefore == 1000)?
Hi! Excellent video, the best I´ve found so far and very very clear. I wanted to ask you if you know a way to encrypt or protect de data between the Tx and the Rx. What I mean is, if I have for example: 2 receivers and 6 nodes, how can I make a specific receiver listen to other specific nodes. I´m about to implement this in my town and I´m affraid to listen to other devices that are from other people and have nothing to do with me.
Cheers!
May i please ask a final question, lets suppose there is a fifth client that i want to connect to the network.. how would it broadcast its join/authentication request to be connected to the server while server would not ask them for information.. it may interfere with another broadcasting device.. i would be thankful for your reply and i would use it in my presentation that I'm working on
purchased a subscription to channel to get this code, the code for the server can't work as written. Missing code to set frequency and there are typos that make me think this code was written after the fact and never actually used in the project. I usually like the content of this channel but am disappointed with the code I got from the website for this project
I can make sure this is the code i used, I edit the frequency on the library, like the basic tutorial (another video). Not on the main code
@@miliohm The reason I'm confused is that there are only 3 clients in the code and when you look at the "SendRequest()" function call in the server code for client 1 it's C1 for client 2 it's G2 and for client 3 it's G3. In the client code for client 2 and client 3 they are C2 and C3 not G2 and G3. I don't see how this will work as written. Thanks for your reply
how many client we can add to a server
Excellent. Very helpful. 👏👏👏
How to interface sx1262 lora node
Hello, very good videos, thank you, I need help to connect the arduino or the lora to the lora gateway, I don't know how to do it. I don't know if I have to write any code or add a library.
Wow, it is fantastic tutorial.. Able to make a video on teaching how to make lora mesh turn on and off and dimming lights?
Did you mean control light using lora?
thisis nice video thanks
Hi! Thanks for ur help, I wonder do u think that in olace of use that lora shield as clieny, I could change it by another cheaper like sx1276? Thanks in advance
yeah sure, but you need different library to do that
apakah bisa dengan modul lora E220?
Can you produce a LoRaWAN Gateway Setup video pls that works with helium
thank you for your great video, Is it possible to for Lora nodes to send data to one node and finally last node transmit the whole data to gateway?
Sure
Hello my friend, I would like you to shoot a video like this one only using the Ebyte E220-400T30D module, I am having difficulties in making a project that has 4 clients and one server using the Module E220 that I bought. I will be very grateful and I think many people too, I couldn't even see a video of this module.
Tks a lot..this is what I'm looking for...btw, can you use a multi channel freq module as the server for this kind of topology (without connecting to a lorawan server I mean)? Thank's again...👍👍👍
When you say multi channel, does that mean you could run upto say 7-11 Nodes?
Hi friend! Great project! How I can get the code for this project?
Yoi can join the channel and get the link at community page
Mas mau tanya di dm boleh ga?
can the same be done with an stm32 microcontroller instead of arduino board
should be, but maybe there's no library there. So you need to make it your self
How many transmitter (client) are allowed with a single receiver..??
I'm not sure, but I think it's unlimited
@@miliohm can i use this library on esp32 Lora oled module???
thanks for this video is really helpful. hope u can do it for the future by changing the receiver or server from Arduino to a raspberry pi. just suggestion and requested
ok, I'll take a note on that
hello, i have a final project using lora, can i ask you some question ?
Sure
@@miliohm in lora network, when 1 node send data, all node will receive right?
@@minhmanhuynh8516 right
@@miliohm Can a Node connect to multiple LoRaWAN networks/servers
hello, i wanna ask u about how to save the data from lora server to database like postgresql or mysql? thankyou so much
harus ada akses ke internet mba, misal pake SIM800L atau pake wifi dengan NodeMCU. Abis itu bikin php buat nerima data dari perangkat tersebut. di file PHP itu berisi program untuk masukin data ke MySQL
@@miliohm wah oke mas trimakasih hehehe
@@miliohm maaf mau tanya lagi, jadi node mcu nya dipasang di transeivernya kah mas? atau di gatewaynya?
@@vinimeiriska9225 you should put that at your gateway. When you receive the data, then you send that to your server with wifi.
@@miliohm oke, but im using gateway dragino olg01, not made up from node arduino🤔 so literally how could setting it up with nodemcu/sim800l ? Im so sorry for asking more, im newbie😄
