LoRaWAN Simulator (works with ChirpStack)

[Processing uplink frame error]

Hi everyone!

I have installed LWN Simulator and ChirpStack server on a Raspberry pi 4. Specifically I have installed chirpstack using docker compose.

I have managed to have communication between the two as I can see in the dashboard my active virtual gateway that I created in the simulator.

But I can not see the devices that I register. I set the same parameters both in the simulator and in Chirpstack (Name, DevEUI, Region and Otaa supported with appKey). The location is a few meters from the GatewAy.

In the log I see a chirpstack network error: Processing uplink frame error.
Error: Zero items in collect set

Any help would be welcome.

Thank you very much for your help.

So if I will create the devices by hand, I simply can not simulate 50k devices with this LoRaWAN Simulator ? Am I right ?

Hi everyone!

I have installed LWN Simulator on a Raspberry pi 3.
The Raspberry pi ip address is: http://172.18.96.100:8000 (This is an intranet IP address)
LWN Simulator is working on Pi.
I see on this console log:

I set the virtual GW on pi IP adr.: 193.6…(this is my ChirpStack NS and AS on a different computer. Windows server 2008 R2 )
The Chipstack server is looking at my Raspberry Pi on the intranet network.

The 1700 port is open.

I set the Chirpstack AS on this tutorial.
Notes for ChirpStack

But on the server I can’t see anything.

Can anyone help solve my problem?

@pippok96 , I did all you recommended, but I still have no active gateway in chirpstack.

sergorl · April 6, 2022, 2:14am

@bakok , do you find solution?

Fedyfausto · April 19, 2022, 2:15pm

it seems a configuration problem, could you send to us more information?

sergorl · April 19, 2022, 3:58pm

@Fedyfausto , what’s exactly info you need? I can collect logs (of all services) and publish configuration toml files. Is it OK?

tapitapo · March 29, 2023, 2:07pm

Hello,

I’m looking to try LWN-Simulator, I also have installer portainer which use the port 8000.

How could I modify the port used by the simulator?

Regards

Edit:

Here is the answer:

Modify the config.json with the desired port
Modify the docker-compose.yml to reflect the new config
build the application with docker compose build (this is the step I have forgotten)

tapitapo · March 30, 2023, 5:50am

Hello, I have the same problem, did you find a solution?

ernestoax3 · July 23, 2023, 4:36am

Excuse me, i recently installed LWN simulator to create a network for a project and i would like to know if there is some kind of manual or something like that. I am new to this, so i don´t know much, but i would love to, so i really like to know if there is something like that. Thanks in advance.

Fedyfausto · September 27, 2023, 10:10pm

Sorry if I disappeared but we started to better manage the GitHub for the various issues, indeed many collaborators are actively participating in the project being open-source, you are all welcome!

kernl · October 29, 2023, 11:24pm

Did you end up finding a solution for this?

lakshmana_Chimata · November 23, 2023, 1:00pm

did anyone found solution for this, I am able to see Gateway, but Device is coming as never seen

lakshmana_Chimata · November 23, 2023, 3:45pm

@brocaar can you help with this, I have added LWN simulator (GitHub - UniCT-ARSLab/LWN-Simulator: A LoRaWAN nodes' and network simulator that works with a real LoRaWAN environment (such as Chirpstack) and equipped with a web interface for real-time interaction.) as part of the chirpstack-docker and did a build, I was able to connect to gateway bridge via 1700 port, gw connection is success, but device join accept message is not reached to device, either mqtt message is not reached to gw bridge or gw bridge not forwarding the message to gw added. This is the reason I wanted to create binaries of chirpstack server and check the issue

brocaar · November 23, 2023, 3:58pm

I’m sorry, but I can not help you with this.

Fedyfausto · January 30, 2024, 11:05pm

Excuse me for the time, we are working on a new release (1.0.3). Meanwhile, try to use the 1.0.2 from the releases section of GitHub:

Also, new scientific publications and video tutorials are coming out soon!

Hi, dalmeida… I am interested too in the simulator. Do you have some information about how it works?
