Initialize a GPRS modem by using C

[tfdo]

As my final year project I'm planning to do a SMS plugin system from which you can send & receive SMS.
For this I'm planning to use C language & send SMS by using a GPRS modem.
I have been searching details of how to do this & I know alittle about how to use AT commands.

What the problem I have now is how to initialize the GPRS modem by using C.

If there's any place (web link) where I can get some sample codes or a tutorial it will be real help.
I'm planning to plug this SMS system into a VB.net system & also to an exsisting system built using oracle forms,which is already up & running.

If you people can give me any ideas about this within this week it will be great.

Thanks.

Yes, that does happen, especially on sites like this one where the moderators work for free - but you do have at least 30 views of the issue.

So when you say initialize, what do you mean? Are you trying to load firmware on it? Set configurations, or just use it to connect to something else?

I need to initialize the Modem to set the configurations so that I can send SMS using it.
I hope this answers the question you have asked.

I really don't have any idea of how I have to do it. I'm trying to learn it from 0.
If there's any other better ways to send SMS using a GPRS modem, please let me know.
Thank you.

I don't know anything about sms or grps modems, but are you limited to c or are you open to other ideas. Here is an some sample code about SMS and using .net, but looks like most of the information is about phones, so i don't know if it will be of any help. Heres the Link

Thanks alot. It will be helpfull if I'm using .NET.

Yes. I planned to use C for this is because it should be a plugin system. I need to plug the SMS system to two systems. One .NET and the other designed in ORACLE forms. If I use .NET for the SMS system, I don't know whether I'd be able to connect it with the ORACLE system. So I can't take that risk.

There must be a way to do it in C. If you happen to come accross any details of it, please let me know. I will let you know if I find something new.

Thanks again!

I'm pretty sure that link gives you some very good insight into the details. Did you look for an SMS library in C? Or a library that might have those methods? Did you look at the library itself, see if you could implement it if you don't find one?

Perhaps I have no clue about those projects, but could gnokii project and xgnokii help you on this? They are used to communicate with mobiles and use their protocols for sending sms. Could that be enough?

This is a difficult question, I have not done any GPRS radio stuff before. But tell me a bit about your platform. What are you trying to do it on? Who is the mfg of your GPRS radio? Do you have any documentation for the radio driver?

Hello!
I'm very sorry for not repling for a long time.

Even I don't have any idea of how to do it. It's just an idea for a research project which I have to do. Unfortunately, I don't have any documentations on the GPRS modem.But I don't think that it is necessory also. As, initializing a modem would be same for any unless for some small changes.

The platform ofcause will be windows as I am planning on to use .net. The problem is not with interoperabilit y. I just need to know how to initialize the configurations of the modem using C.

Thanks for all of your comments.
Hope I'll get a positive idea soon.
