My confusion relates to programming of esp32 serial ports. I don’t think what I’m trying to accomplish is specific to the Sparkfun board but it is clearly not related to Seeed Studio products. I mistakenly associated Seed Studio with the esp32 processor line when in fact the cpu’s appear to be made by Espessif.
I tried to delete my post from the Seeed Forum but I cannot.
As always, thanks.
