Hello. If someone could help I would appreciate it. As you know an sms message can be sent from a mobile phone to an email address by just typing in the address re: "nick@avproecm.com" instead of a destination phone #. How do I configure the SIM900 to be able to accept the email address. I only get an "error" message.
The sms messaging service then normally sends via through a gateway to the email address. My application is in an area where I have no internet service. Thank you . Regards. Nickatnite
To send to an Email address you add put the address in front of your message, followed by a line feed, and send the message to your service providers SMS Gateway Number. For example to send a message to "John@google.com" on the AT&T network you would do the following:
Code:
Send the following commands to the module - Each line must be terminated with a 'Carriage Return':
AT+CMGF=1 - Set the module into Text mode
AT+CMGS='111' - Start sending SMS, 111 = AT&T SMS Gateway Number
- The module will return'>'to indicate it is ready for the text
- Send the text...
John@Google.com\nHello John, this is a text message from the SIM900
Ctrl-Z - follow message with ctrl-Z and Carriage Return

Well it seems I got giddy too soon. The crtl z issue is giving me problems in the Arduino serial monitor. Cannot get the Sim900 to send a message. I press contol and z simultaneously after typing in a message and nothing happens. I do not press carriage return first. I can press return and type in "26" or 0x1A with return. Nothing. Have been reading online for four hours and cannot find a solution. The sim900 will receive messages but will only print out the first character of the message in the monitor. Any help?
