Hi to all.
Hope I'm in the correct forum here.
I have a board that has a micro(pic24fj256ga106) , a GSM module(SIM900) and some eeprom.
The micro talks to the GSM module via it's serial port using AT commands , pretty standard.
I use it to control various IO via sms or incoming calls. It also sends sms's on input triggers.

If I want to change it to "host" a website and control the IO via a webpage , do I have all that is required.
I have got a pic32 ethernet dev kit that I got working , but that was via the ethernet port.
How do I access an "onboard" website via the GSM module. I've never done anything like this ,
so I'm totally in the dark here :0(. I'm assuming the GSM module is online and I know it's IP at this stage.
Any pointers or help appreciated.

Cheers
Neddie

you have to direct TCP/IP traffic from the GSM unit to your TCP/IP stack. If you study the ethernet code, you can see that data from the ethernet port is sent to the stack.

For the GSM unit you need to make a driver that extracts TCP/IP data from the AT commands and then send this to the TCP/IP stack and vice versa..

Thanks , I'll look into it.
Sounds complicated though :0(

with ethernet it should not be complicated as the library is well documented. If you know how to implement a TCP/IP stack then half the job is done. If you are using Microchip's TCP/IP stack then there should be no problem, as it is well documented.

You have to figure out how data is sent/received via AT commands.

thanks
