I have a complete SIM900A module.

I am able to send sms over it.
But now I want to send data using GPRS over static IP address.

I don't know how to proceed. Any example code.
IP address, do i need to have internet plan on SIM card or what?
Any example code?

Edit: I have to interface with microcontroller with uart , Rx,tx & Gnd

 

Any help on that??

Update:
I have got one static address. But I have some confusion:

1. I was reading this, & on post#3, someone has posted code:
http://www.edaboard.com/thread219547.html.

2. Now I have one Sim900A module with SIM with data plan & a static ip address.

3. What to do now, I make my sim900a module client & keep on sending data on that static ip address

i.e on client side:
AT+CIPSTART=”TCP”,”188.33.176.204”,”8080”

The ip space abobe I have to put my static ip address.


4. Now what will happen? data sent over address will go to that ip adress i.e server & there I have to write some code which extract data from that staic ip address & finally store in computer.

Is that whta will happen
