Hi Jeff,
Thanks for taking the time to respond.
Ideally I would like to determine the status of the two nodes from my node-red flow and if for some reason the mtac-lora card is down or unable to transmit packets, I would like the upstream connections to know of status of mtac lora card, so that there are no downlink messages sent from our upstream systems, so they don’t pile up messages in the conduit.
As far as my 3rd question, was if I can’t determine the mtac card status from my node-red flow, I was just going to see if I could subscribe to the LORA MQTT broker messages, But was unsure how best to achieve this? I did see this MQTT LORA URL. But haven’t used MQTT broker ever in node-red flows.
Thanks,
Yogesh
