Hello!
I'm trying to solve a problem regarding using the Arduino Cloud. My main problem is that the moment my product (Arduino OPTA) loses its internet connection, all the data in my variables is deleted. I tried to do some forms with the Cloud function "addCallback" but I was not successful either.
My main objective is to at least store this variable and if the internet connection is lost, this same variable returns to the same value the moment it reconnects to the Internet. Remembering that I thought about using the product's Flash but it has a useful life of writing and erasing and I'm sure that this useful life would be exhausted in a short time.
Anyone to help?
