Thanks for the info. I have found it all works as advertised, at least initially. My Boron functions properly for about the first minute, after which it becomes unresponsive to ping attempts.
I have re-programmed the Boron numerous times, created new networks, etc., but the result is still the same, the end result being that the mesh functions continue to be unavailable for my hardware. BTW, I am using a Telus IOT sim card. Everything works fine until I associate the Boron with a network, after which it craps the bed after a minute or so.
Maybe I need to adjust keepalive?
