I've been using this cellular module to send me updates from projects lately. http://www.sparkfun.com/commerce/product_info.php?products_id=9607. What I have been trying to figure out is how to receive a text. Can I send an AT command to check for new messages and if there are any to parse out everything except the text body? Does anyone know of a way to do this? Example code?
I’m not familiar with the SM5100, but I am very familiar with the AT command set. I designed the DroneCell - http://narobo.com/products/DroneCell/DroneCell.html so I’ll say what I would do on a DroneCell and hopefully the commandset applies by you as well.
Your module can be configured via the AT+CNMI command whether or not to display unsolicited response codes when it received a text message.
Then sending and receiving texts are as easy as this video I made: http://www.youtube.com/watch?v=GD8DLryzSL0&feature=related
IIRC there is a command for reading if there are new messages, such as = “REC UNREAD” or something like that.
Good luck with your project.
