Yogesh,
1) Is it possible to query the status of the two LORA i/p and o/p node?
Where are you wanting to query from assuming this is different from question #3?
2) I am guessing the connected state indicates all is good with MTAC LORA card?
That is correct.
3) If not how would I be able to query and determine from node-red flows all is good with the Attached MTAC LORA Card and the conduit can successfully receive and send LORA packets?
The only way to tell if sending and receiving will work with LoRa is to actually send and receive packets between the gateway and the mote.
Hope that helps,
Jeff
