To send a txt message:AT command - AT+CMGF=1This command sets the text message mode to 'text.'AT command = AT+CMGS="xxxyyyzzzz"(carriage return)'Text to send'(CTRL+Z)This command is slightly confusing to describe. The phone number, in the format (xxx)yyy-zzzz goes inside double quotations. Press 'enter' after closing the quotations.Next enter the text to be send. End the AT command by sending CTRL+Z. This character can't be sent from Arduino's terminal. Use an alternate terminal program like Hyperterminal,Tera Term, Bray Terminal or X-CTU.
so things are gonna get ugly...
IT SEEMS YOU DID NOT READ MY POST THROUGH. i WANTED THE SMS TO BE SENT TO A NUMBER WHEN THE "ENTER" KEY IS PRESSED.not Ctrl+Z
why don't you take up the offer, it seems to me it will be the easiest $200.00 you could make.
The arduino will know that the message is complete when it sees the ascii code for "enter" in the string.
I beleive it is 13.
