Hi
I have one meter which is connected to my RabbitMQ and I am trying connect with this meter from Gurux Director but it is connecting how to resolve it.
Hello!
I have the same environment as described here: https://www.gurux.fi/forum/16596 but there no solution to the problem.
My meter natively supports MQTT protocol and I want to communicate directly using DLMS Director without using Gurux Bridge software. But when I try to do so the only messages that come to my topic are:
{
"id": 28,
"sender": "f06d16cd-e86c-48fb-8592-aad2955cc4da"
}
and then without receiving a response, the following message arrives

Hi
I am new to dotnet and never worked on it.
On reading the instructions, I downloaded the MQTT files from Github and tried to build the broker and bridge.
But .dll files are not created.
Can you tell me the steps to build and run the MQTT broker and bridge

Hello,
I am working in a implementation of MQTT for a Smart Meter through LTE. I am not using the Gurux.bridge because my meter supports natively MQTT.
The meter is suscribed to a topic "meter", and also Gurux DLMS director is configured to use the same broker and topic.
When I click on connect in Gurux DLMS director, I received in the another side the following frames:
hi mikko,
I am implementing an UI where i take obis from xml file, parse and set some values and send to meter,in this I need a small clarification
2)In the server code, I see there in init() function in GXDLMS base where we add different objects to meter,
before that there is a setKek(function) what is the purpose of it ?.
3)After adding objects to meter in init(), there are 3 steps before server initialization as follows:
getItems().add(new GXDLMSCompactData());
getItems().add(new GXDLMSDisconnectControl());
Hi Mikko,
Currently, I am testing IS15959-2 meter.
We are sending multiple requests to the multiple meters by calling middleware service. The service is sending request payload torespective to meters.
And all meters will send a response on MQTT.
For that, we have created a single MQTT client and multiple subscribers.
Now the case if we sending SNRM requests to multiple meters, all responses will be received on subscribed events. In that case how to handle all responses using a single MQTT client.
Hi Mikko,
I am testing meter using MQTT interface. I am not using the Gurux broker and bridge in this testing.
On MQTT subscriber I got ACK and response from meter.
Before we getting a response, we received ACK from the meter.
Now, using that ACK we can check weather response will receive or not.
If ACK is true then a response will receive from the meter.
If ACK is false then a response will not come from the meter and we need to send the request again.
So In that case how I can handle ACK in media.Receive event?
