Unable to communicate with MQTT

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:

{"id":1,"sender":"72346f17-90e1-4a7e-aeb7-2104a0891c6e"}
{"id":2,"sender":"72346f17-90e1-4a7e-aeb7-2104a0891c6e","type":3}

Afterthat, Gurux DLMS director says: Invalid topic 'meter'.

In the received data I cannot see payload or data related field, so I am unable to process into the meter and generate an answer.

Any help will be appreciated.

Thanks.

Hi,

There are differences because MQTT is not defined on the DLMS standard. Can you share what meter returns and we can check ho to handle this case.¨

BR,
