I want to develop the following system:
I must connect the C8051F320 microcontroller http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/C8051F32x.pdf&src=ProductMatrix (which is on development kit C8051F32x-DK http://www.silabs.com/pages/DownloadDoc.aspx?FILEURL=Support%20Documents/TechnicalDocs/C8051F32x-DK.pdf&src=SupportDocLibrary ) with the GSM modem 13006b http://www.radel.gr/radel_modems.html, through one serial cable (handmade:9pins to 15pins).
The microcontroller should send data to the GSM modem using the serial cable. Then the GSM modem sends the data to a web server (which I’ve set up) trough a TCP/IP socket (using GPRS network).
It’s the first time I’m trying to use GSM modem, so it’s very difficult for me to understand what I should do.
For the moment I’m trying to familiarize with the modem. I connected my PC (Windows 7, 64bit) with the modem, I used the program hercules (3.2.3) and send AT commands to the modem. When I tried to communicate with the web server (with AT commands) I couldn’t do it. After searching internet I read that I can’t do that with AT commands (with my modem). I also read that the easiest way is to communicate with a web server through a TCP/IP socket is to use Open AT. How can I do that? I have to install anything at the modem?
Is the above system realistic? Or I should try to send SMS?
