We (me and my group) are trying to implement a system LoRa-Gateway-MQTT Server, as show in the PICTURE 1.
Our comunication between LoRa and the gateway is working, our MQTT server is working. But we can’t figure out how to integrate de gateway with the MQTT server. We simply have no ideia on how to configure the adress for our MQTT server and the varibles on the gateway. We think that the fields for this configuration is in Global Integration (MQTT Topic Template Setup), as show in the PICTURE 2.
But we don’t know the correct syntax for the TOPIC and PAYLOAD and in what field these informations must be insert.
We are using the app Automate (With MQTT Publisher) to send data (to check if the problem is with server) to our MQTT Server by LAN network.
The configuration that we are using is show in the PICTURE 3.
And this method works, our data is being received on MQTT Server.
The question is, in short, how to declare these variables and in what field inside the RAK7249 to do the communication between Gateway and MQTT Server?
Thanks for your atention.
