Where do I find my gateway bridge's port and IP? I assume the IP is 127.0.01 since I have it installed on the same virtual machine as my application server and my network server and I'm executing the simulator on the same machine. I tried looking into the ports that my machine are using with: sudo lsof -i -P -n | grep LISTEN And it was 3001. But when I try to run the simulator, it gave me this error: 2021/09/14 16:50:23 GW[gw1] [ERROR]: No connection with 127.0.0.1:3001, it may be off

Hello,

I am having Ubuntu 18.04 running as VM on windows host. In the same VM I have installed all the Chirpstack components namely Gateway-Bridge, network Server and Application server. I have installed the LWN-Simulator too in the same VM but while executing the 'make run' command I am getting the error as :

2sudip@sudip_ubuntu:~/LWN-Simulator$ make run 2021/11/09 14:37:10 LWN Simulator is online... 2021/11/09 14:37:10 [WS]: Listen [ 192.168.1.5:8000 ] 2021/11/09 14:37:10 [WS] [ERROR]: listen tcp 192.168.1.5:8000: bind: address already in use

192.168.1.5- is my VM ip address.

The same 8000 port I have used while adding network server in the application server web interface. 'localhost:8000'.

What shall I do to get the websocket of the simulator to get connected?

Please help!!

Hi I tried sending "51282412059f23190000000000000000000000000000000000000000000000000000000000000000" in device payload and i am getting base64 encoded data on chirpstack as NTEyODI0MTIwNTlmMjMxOTAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDAwMDA=

whereas expected encoded data is USgkEgWfIxkAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==

i tried finding the issue and in order to get this data correctly i need to do a hex decode , but i am not sure where to do it

i am addding the sample sudo code here

package main

import ( "encoding/base64" "encoding/hex" "fmt" )

func main() { fmt.Printf("expected: \n USgkEgWfIxkAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA==") payload := "51282412059f23190000000000000000000000000000000000000000000000000000000000000000"

current_output := base64.StdEncoding.EncodeToString([]byte(payload))
db := decodeHex([]byte(payload))
expected_output := base64.StdEncoding.EncodeToString(db)

fmt.Printf("\noriginal encoding \n %s\n", current_output)
fmt.Printf("new encoding \n %s\n", expected_output)

}

func decodeHex(input []byte) []byte { db := make([]byte, hex.DecodedLen(len(input))) hex.Decode(db, input) return db }

kindly suggest where this decodeHex needs to be put

I have copied DevEUI to Chirpstack's device. The gateway can be associated correctly. But "Last seen at" is always "never" for device.

I created Gateway Bridge's address: 127.0.0.1:8081 and virtual gateway with MAC 29272682558d9843.

So how to connect virtual gateway to ChirpStack open-source LoRaWAN® Network Server?

Is it possible to set up a virtual device with a binary payload?

I would like to simulate a LoRaWAN payload of bytes that cannot be represented by a simple ASCII string, but there does not seem to be a way to configure that in the UI.
