I´am looking for a command which is able to say me in my sketch if Blynk is
connected on my ESP Board or not. So later for a bool for true or false.
I play with the keywords
but I do not found the right speeling, grammatic or keywords.
I thing it could be very simple, but i thing i do not hit the right speeling, grammatic for the commands.
So anybody can help me with the right speeling, grammatic or keywords ?
