I'm facing an issue using the encoded data function.
I activated the encoded option and I kept the default data objects :

However, Chirsptack don't seem to receive the whole data when i sent it as you can see :

So I tried to add another object and sent a new data payload but the number of encoded digits is still the same.

ERRO[1899] processing uplink frame error data_base64=“AAgHBgUEAwIBAAAAAAAAAAAAAMyVJYI=” error=“join-request to join-server error: unmarshal response error: invalid character ‘<’ looking for beginning of value”
Thank you !

Dear Ignacio,
I tried to run the "make" command in the lds folder, but it stops with an TLS authentication problem.
I fixed it by reinstalling "Go", with this manual:

• https://github.com/golang/go/wiki/Ubuntu

for Ubuntu 18.04 LTS

Maybe you want to put it in your "read.me", so anyone can use it directly.

Best Wishes
Max

I was trying to run this on docker but not successful is there any way
using a image of golang:1.12
docker run --rm -it -v "$PWD":/usr/src/lds -w /usr/src/lds golang:1.12

then install the dependencies
root@e16a31086b10: apt install build-essential xorg-dev libgl1 libgl1-mesa-dev libgl1-mesa-glx redis-server

and run the "make" but the executable didn't work

PD: Exelente Trabajo, Saludos desde Mexico.

Hello,

I've tried yesterday the simulator. I succcesfully run the gui version and so i've decided to try the cli with the same configuration file but each time i do a : run go main.go
I have an error that say :

# command-line-arguments ./main.go:171:15: undefined: lds.DataRate ./main.go:190:7: undefined: err ./main.go:212:14: undefined: lds.RxInfo ./main.go:246:4: unknown field 'Timestamp' in struct literal of type "github.com/brocaar/loraserver/api/gw".UplinkRXInfo ./main.go:276:22: device.Uplink undefined (type device has no method Uplink)

I'm a beginner to go so I don't truly understand where it's come from so if you can add some documentation on the cli version and how to run it, it'll be a great help.

It is very useful for some non-developer users to have the compiled version of the program, so adding it to the respository could be amazing.

It could be accomplished using the github actions.

Hi,

I would like to make some simulations with the device simulator (stress tests, statistical verifications, etc.).

I thought of maybe extracting the relevant parts of the code, or write an automation that would click on the UI.

Is there a better way to do it? Like using the LDS as a Library?

How do you suggest to approach this problem?

Thank you very much!

Hi,

I tried (and then looked at the code) to send a join request thorough the packet forwarder but it seems like it's only supported with MQTT server. Is there a way (or you thinking of extending it) to send join request and receive it through the packet forwarder. Cheers

Syd

Hii, @iegomez

i have downloaded release source code but how can i run in windows platform

can you please provide step for open in windows platform

Thanks

Hi, I got some very annoying GUI crashes when scrolling the output console window.
Seems related to imgui.
Do you have any workaround ?

Thx

Hey, @scartill!

I've given it some thought and I don't believe I'll be doing any more changes nor will I be reviewing to this repo, I just can't find the time and there are other priorities I prefer to attend to. Since you've done some great work with it and I know some people still use the project to aid in their ChirpStack testing, I'd be happy to transfer it to you if you'd be willing. Let me know what you think, but feel no pressure at all! If you aren't able to gain ownership, I'll just archive it and put a notice for others to fork and continue any work if they think it's worth it.

Thanks again and cheers!

Hi everyone!

I am working in an environment with separate machines for the Chirpstack Network Server, Application Server, and the Device Simulator. I am trying to send a Join Request using the following configuration.

Where:

• lora-ns is set in /etc/hosts as the IP for the Network Server, and mqtt is configured to listen on port 1883.
• On the device part, the device EUI, address, and Session keys are the ones that I chose on the Application Server.
• The App key is the one that I set in the Application Server configuration.
• I set ABP in the device profile.

For some reason, I can see the message arrive to the mqtt on the Network server, but I do not see the Network Server handle it, and the message is not forwarded to the Application Server.

I also have a few questions:

• How should I should the marshaler? Should I set it somewhere on the Network Server part?
• How can I know the Network Key and the Join EUI? Where is it referenced?

I hope you can help me (or redirect me to some relevant documentation)!

Thank you very much!

Hi everyone,

I am trying to build a virtual LoRa environment for testing, based on Chirpstack's server infrastructure.

For some reason, when trying to use this tool, I get segmentation faults when trying to join. I get a segmentation fault at least 50% of the times I click on "Join". Here is one of the error messages:

`panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0xa0 pc=0x91a48a]

This happened with different configurations... This specific error happened when I tried to join a second time, after a first time fail.

I also got this segmentation fault error (I don't remember how):

`panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x91a310]

Hi,

This is probably a newby issue but please bear with me:

I have chirpstack running via docker-compose and am trying to get your client to connect to it.
I've registered a gateway in chirpstack with an gateway ID of DEADBEEFDEADBEEF

I then run the client with no other parameters (i.e. default configuration), and tell it to connect to the MQTT server (localhost:1883)

In the chirpstack log I can see the connection being made, but the it immediately disconnects

mosquitto_1 | 1597846740: New connection from 172.20.0.1 on port 1883.
mosquitto_1 | 1597846740: New client connected from 172.20.0.1 as lds-1597846740191835856 (p2, c1, k30).
mosquitto_1 | 1597846740: Socket error on client lds-1597846740191835856, disconnecting.

The log from the client shows teh connection, but it then exits without any error being shown:

phil@pol-r:~/go/github.com/legomez/lds$ ./gui
time="2020-08-19T15:17:28+01:00" level=info msg="open conf.toml: no such file or directory"

time="2020-08-19T15:19:00+01:00" level=info msg=subscribed

The last line is an extra log statement I added to check that its getting past the call to mqqtClient.SubScribe()

Looking at the code I can't even see where it would be going next as this seems to be the complete callback on the "connect" button.

Any ideas or suggestion on what I can do to debug this further ?

I am trying to use your software to simulate a device connected to the ChirpStack platform I had deployed in a server. However, when I try to connect it, after sucessfully conected the MQTT client of your software, I had some error messages from the software.

Could you please, help me with this setting.

Hi,

Building on Ubuntu 18.04 I found that I also needed the following to get the build to work:

sudo apt-get install libgles2-mesa-dev

Small point I know, but you might want to update the readme.

Hi,

I noticed that my chirpstack server discard uplink frames using packet forwarder from lds because tmst parameter type is wrong. Indeed it is supposed to be unsigned 32b from the spec and it is defined as uint64 in lds code.

Do you confirm ?

Hi,
I made successfull activation test in OTAA between lds and chirpstack server.
However, I noticed that it fails in ABP because device addr stays 0 when sending uplink frames (when reading data from redis)
I did some slight modification in the code to make it works but I am surprised that nobody reported the issue maybe I missed something in the conf.

Hi there,

I built the compiled file and I correctly have the "gui" compiled file which appears using the "make" command.
When i tried to load it with ./gui it results in the following error :

The 5 first error lines don't seem to be an issue for the code loading but the last one stop the window's launching.
I seaked out a fix on the web but nothing worked for me.

Can you help me please?

PS : Sorry for the topic I'm not very familiar with the go programming language

Informations about my environment.

OS : Linux UBUNTU 18.04 LTS
OpenGL version : 3.3
Go version : 1.16.3 linux/amd64

I've compiled lds on osx: Redis is answering pong at ping command, GUI is ok and connection to our lora server works.

By the way at device join click on the lds gui interface I receive the following error in the built-in console:
level=error msg="redis get key error: redis: nil"
