Did anybody ever connect a Siemens C45 (or similar Siemens mobile) to the Arduino Mega or Duemilanove to send text messages using AT commands?
I'm mainly interested in wiring the mobile to the mega (serial or sorwareserial). Can I connect the mobile directly to the ports of the mega or do I have to consider anything important?
Up to the used connection (serial or sorwareserial) how can I execute the AT commands?
Thanks for your help!
