Well after running for some time with the WiFi S6B, and still having problems after it has been running for a couple of hours,
I’ve switched to one my target field internet comms of Digi XBee3 LTE-M over Verizon.

Very interesting the Digikey RevXsystems https://dataplans.digikey.com (thanks to @mbarney for the suggestion) has a new low cost 50M/month CAT-M1 plan.
Wow this is excellent!. Based on some recent past experience with a marginal/failing system this is going to be worthwhile.

Since this was a new Xbee3 LTE, I have upgraded the Xbee3 to the latest software using the Digi “TH Development” board. Then with on the LTE adapter on the Mayfly, I plugged in the battery. At its core the sw is @srgdamiano hard sweat with DigiXBeeCellularTransparent.cpp, though I have modified it to show the connecting process to the cell network.

Since connecting for the first time over LTE and Verizon is such an occasional event, I thought I would paste in the trace.

It connected first time… (whew!)
