SIM900 library for Arduino Uno & Pro min

Using Arduino Programming Questions
1

Dear All,
I am very frustreted and tired.
I just ordered and get a SIM900 board. Before getting it, I fond serveral time the SIM900 library but stupidely I never bookmarked it.
Now I would like to test my card, I can not find it any more

Someone know where to find the SIM900/908 library?

Cheers

Google does:

Hello,
Yes I found it, as well, but I am not really sure about this.
Do you have exeprience about that library?

I would like to use that library with that module:
http://store.open-electronics.org/Breakout%20SIM900%20GSM%20Module?filter_name=Breakout%20SIM900%20GSM%20Module

Do you have an experience with SIM900?
I am trying to make it working but it does not, and I am poor with information and datasheet.
Do you you know a tutorial?

many thank
Pierre

Hi

I have a http://www.ebay.co.uk/itm/GSM-GPRS-Shield-For-Arduino-/230911052682?pt=LH_DefaultDomain_0&hash=item35c35f0b8a

The gsm shield has downloadable code at the bottom. I made a download. The instructions
say you should edit GSM.cpp and change the rx or tx based on your board.

The issue I have is compling the GSM.cpp code

The solution is trivial. Fix all the errors.

Hi

Thank for the reply. So I went to tools and add library when I download the GSMSHIELD files. I then navigate
to arduino, libraries, the shield files opened GSM.cpp to edit the rx and tx pins when finished I saved but
when I try to compile GSM.cpp error happens saying that in GSM.h the SoftwareSerial.h file or directory
does no exist. But I do have the library in the version of arduino. I tried copying the SoftwareSerial.h file
from another folder into the same folder with out any luck.

Hope you can help.

Thanks.

Hope you can help.

Not unless you post some screen shots. Your words do not convey near enough information.

I tried copying the SoftwareSerial.h file from another folder into the same folder with out any luck.

From what folder? To what folder?

And, POST YOUR CODE!

Hi

Thanks for the reply. The code would be to much to upload. So just
go to : http://www.ebay.co.uk/itm/GSM-GPRS-Shield-For-Arduino-/230911052682?pt=LH_DefaultDomain_0&hash=item35c35f0b8a

Go to the bottom and download test code. After downloading test code. Open arduino add library and select the downloaded file. Then go to the library file in your arduino and select GSM.cpp change rx and tx to fit arduino uno rx and tx. Try compliing the GSM.cpp and you get an error gsm.h "cant not find SoftwareSerial.h" . I tried coping SoftwareSerial.h and SoftwareSerial.cpp to the same file but no luck.

Hope you can help.

What manufacturer of GSM shield do you have? What version is it? I "THINK" the GSM might only work for the Arduino GSM shield. But there are many other manufacturers.

Hi

All the details about the module are on the link from previous posts. The schematic and test code can be found at the bottom of the page.

Thanks.

Hi,

Can you guys help me out with my SIM900 on my MEGA?

I posted here:

http://forum.arduino.cc/index.php?topic=325525.0

Im trying to understand either how to not use the included Arduino src/GSM library or if I should make a sketch to use that pre-packaged GSM library instead of my SIM900 library?

Thx

The way to use the GSM library is to buy a GSM shield from Arduino.

Since you don't seem to have one, using the library that works only with that hardware seems pointless.

Why are you even trying to? Not using a library is so simple that it really doesn't need explaining.

Well, I bought a SIM900 breakout module and so I was getting errors because my project was pulling in the GSM.h that comes packaged with the Arduino IDE.

Im not interested in using the AT Commands directly. Im interested in using a library.

Last night I found and downloaded the SIM900 library from Github for the SIM900 module. Now Im just trying to figure out how to use the examples included with that library.

Thanks
