Why does "LoRa.begin" fail here?

@srnet we're not in a place where we could hire out for a LoRa person currently, unfortunately...

Interesting. I'm definitely not sold on LoRaWAN if it's counterproductive to my purposes. Could it be something like LoRa IOT nodes, talking to a LoRa gateway, which then simply extends into something like ThingsBoard?

I'd still like the growing environment (greenhouse) to collect data at some point (plant growth trends, temp and humidity trends, solar trends, etc) too, if possible...
