Hello
I am working on a project that requires a Siemens PLC to send a SMS via a Cinterion modem.
I can send and SMS with the proper AT+CMGS, only if I right the code on the Hiperterminal. If I run the same sequence of AT codes in the PLC the text sent is filled with “@” characters before the real text message.
What could be the problem? Do I have to specify to the modem the length of the message, or where it starts?
Thanks very much in advance!
