My arduino program works well. But when I use Smail, does not work. I do not find the error.
I must use another email?
Other data would be good?
You can't use external parametres with the SMAIL command. There can be nothing between the square brackets, see page 22 in the manual
Thank you, I have seen: Gobetwino manual + Using the Gobetwino sample code + gobetwinoXLtest.pde, but .... :~, I have none at all clear. I try to elimiar inside the brackets. I need to find a simpler example to the program. one blink, for example, sending data.
