mqtt broker to json-scada connection

[jaanu-11]

I have mosquitto broker v3.1 and I'm using arduino to send my data to mqtt broker (mosquitto) and from there i want to send these data to json scada , when i downloaded windows installer inside it in mqtt-sparkplug folder i given my mqtt ip adress , username and password . when im building all mqtt data is getting to mqtt broker and im checking it in mqtt explorer , but im unable to configure whether these data is going to json-scada or not, in json scada web page nothing is showing and in log file im getting this:

2023/08/03 11:15:17.632851 find

im unable to figure out where is the issue , is there any way to confirm whether json-scada is connected with mqtt mosquitto broker or not?

thanks in advance

This log is just for calculations.
To see mqtt logs do this:
Go to windows services and stop JSON_SCADA_mqttsparkplugclient
Or do in cmd as admin
net stop JSON_SCADA_mqttsparkplugclient
cd C:\json-scada\src\mqtt-sparkplug
\json-scada\platform-windows\nodejs-runtime\node.exe index.js 1 3

In Inkscape Sage created my SVG file , how to create tag and how to do communicate with my Device collecting Data ?

Actually My mqtt broker doesn't have spark plug b device so I'm confused about the connection between mqtt broker to json scada i even checked the path you mentioned...We can't see our mqtt data in log files so how can i see my realtime data in json scada? Any page to see?

[riclolsen]

Please try this and post the results

Open cmd as admin
net stop JSON_SCADA_mqttsparkplugclient
cd C:\json-scada\src\mqtt-sparkplug
\json-scada\platform-windows\nodejs-runtime\node.exe index.js 1 3

I'm getting this
, so now i can see my topic name but im not receiving data and starting it is not showing that it is connected to my mqtt broker

Should i do any other configurations for mqtt? If i should do where should i do? I'm not using mqtt spark plug...I'm just using mqtt broker

It is connected to test.mosquitto.org, remove it from the endpointURLs. Leave there only your broker address.
Remove spBv1.0 from topics list.
Leave publishTopicRoot and groupId empty or it will publish JSON-SCADA data to the broker.

Yes now connectted to my broker i can see
Mqtt client : connected
Process: active
But i can't see my mqtt data which is published to mqtt broker here, so how can i see my json data? from svg tag? or directly json data is also visible in terminal i mean here Itself?

[riclolsen]

Remove spBv1.0 from topics list. Put # in the topics or a valid filter.
Leave publishTopicRoot and groupId empty or it will publish JSON-SCADA data to the broker.
Post the new logs.

[jaanu-11]

Yes i did the same thing, it is showing my broker is connected but i can't see any json messages there, how to see my json data which I'm sending to mqtt broker?

[riclolsen]

If it is not in the logs it will not be anywhere in JSON-SCADA.
Use a GUI client (MQTTX , MQTT explorer) to check your published data in the broker.

I have detected problems with the MQTT driver in version 0.29, now fixed in version 0.30!
