and yes i have set my jumpers of the GSM as follows:
Tx - pin 4
Rx - pin 5
Just help me out with the library modification.
I am just banging my head against the wall ryt now.
Will be of great help...if noticed.

I'm sorry but i don't know that kind of Shield, If the simple pin modifications
doesn't work I don't know how to help you. The only think that I thinked is try
simply to invert tx 5 and rx 4. Let me know if you solve the problem. I
actually suggest to you to think about to buy the open-electronics model, on
which this library is based:

sim900 is same for any type of shield it uses. :)
So it should work for this shield too.
I am just facing the problem interfacing it with the pins allocation inside the
library "GSM.cpp".
dont you think that we should set the rx tx pins on arduino to INPUT.
i mean e.g. pinMode(rx, INPUT)
what do u say???

The pin are set in the library. Try this:
Modify GSM.h de-comment #define DEBUG_ON, load the example sketch AT e post
here the output ;)

hey bro...i tried searching "#define DEBUG_ON" but its not there in GSM.h
i downloaded the "GSM_Shield_GPRS_Ver_3_02_(IDE100)" version.
plz bear with me... :) u r of realy gr8 help..bro!
i ll send u the GSM.h with the attachment.
jus check it.

hey i got this output:
GSM Shield testing.
DB:NO RESP
DB:NO RESP
DB:NO RESP
ERROR: SIM900 doesn't answer. Check power and serial pins in GSM.cpp
status=IDLE
so my tx rx pins are not set properly.
any ideas?

Did you choose pin that support change interrupt? Maybe is that... Check on
Arduino's page wihch are enabled to this function.
Original comment by martines...@gmail.com
on 21 Jan 2012 at 10:39
the pins are d2 or d3.
will that help??
hey listen..my shield came with a library which jus show errors on compilation.
it uses "NewSoftSerial.cpp" and "NewSoftSerial.h" classes.
not SoftwareSerial".
I will attach the library. See if you can get anything.
I guess I am Burdening you with much here....
itz ok..otherwise. :)

heeeeeeeeeeeyyyyyyyyyyyyy
after few swaps of luck on d pins i got this:
status=READY
OK
RDY
+CFUN: 1
+CPIN: READY
bro..i guess i m gud to go..! :D
i told ryt..this will work on any sim900 :)
two steps:-
1. Goto GSM.cpp
and uncomment: //#define _GSM_TXPIN_ 4
//#define _GSM_RXPIN_ 5
and comment in:
#define _GSM_TXPIN_ 2
#define _GSM_RXPIN_ 3
2.Set exact tx-rx pin as defined earlier on the shield jumpers.
i.e. tx - pin 2
rx - pin 3.
and you are done. :)

Hi Raphael, next time open a new issue if it is not strictly linked to another
one. However for the serial is strange what you're writing, check
http://arduino.cc/en/Main/ArduinoBoardMega for arduino's pin.
In the example folder there is a sketch for sending SMS.

Hey max, which arduino board are you using? I'm having the same proble here
with the mega2560, i made the pin replacement but still nothing...Greeting from

Hi everybody..
I have the same kind of problem :
GSM Shield testing.
DB:NO RESP
DB:NO RESP
DB:NO RESP
ERROR: SIM900 doesn't answer. Check power and serial pins in GSM.cpp
status=IDLE
----
I tried to use the 2 and 3 pin for tx and rx AND the 4 and 5
but it still doesn't work.. (in my case the right pins seems to be the 4 and 5
but ???)
I read many post and issues and I saw that many people wrote that this shield
need an
external power.. is it right ???
did you used an external power for this shield ???
if yes what kind of power did you used and how did you connect it to the shield
???
my setup is a GSMSHIELD for futurashop.it and an arduino ethernet (but seems to
be the same than arduino uno) and powered by the usb-to-serial arduino adapter..
when I turned it on the green led on the gsm shield is on but maybe this kind
of power is not enough to run completely this shield ??
thanks for your answer

Yes it needs an'external power source 12V 1A connected to Arduino power input.

hi im using 4 AA type batteries but still cant get signal...which kind of 12v 1
A source are you talking about?
Original comment by oincabo...@gmail.com
on 9 May 2012 at 9:26
sorry but usually an AA battery is 1.5 right? So 4*1,5 = 6...
However the new shield implements the lithium battery support ;)

Thanks max.action07 for your guides.. After doing those two steps still I got
DB NO RESP..
Then I just did a reset(pressing the button on the boards) on the SIM900 and
Arduino, then it started working.. adding this note in case anybody else also
pulling their hairs..

I need help. I'm using the sample sketch GSM_GPRSLibrary_SMS. I've already
changed the necessary pins for the software serial to pins 4 and 5. I can
already receive but problem is I cannot send SMS.

HI
Anyone please help me!!!
i m using Arduino uno and Seeed studio GPRS shield, but I am getting out put:
GSM Shield testing.
DB:NO RESP
DB:NO RESP
DB:NO RESP
ERROR: SIM900 doesn't answer. Check power and serial pins in GSM.cpp
status=IDLE
I attached with power, jumpers D7(RX) and D8(TX) in Seeed studio GPRS shield
I used:
#include <SoftwareSerial.h>
#define _GSM_TXPIN_ 7
#define _GSM_RXPIN_ 8
#include "SIM900.h"
//If not used, is better to exclude the HTTP library,
//for RAM saving.
//If your sketch reboots itself proprably you have finished,
//your memory available.
//#include "inetGSM.h"
//If you want to use the Arduino functions to manage SMS, uncomment the lines
below.
#include "sms.h"
SMSGSM sms;
//To change pins for Software Serial, use the two lines in GSM.cpp.
//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.
//Simple sketch to send and receive SMS.
int numdata;
boolean started=false;
char smsbuffer[160];
char n[20];
void setup()
{
//Serial connection.
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 2400or slower.
if (gsm.begin(9600)){
Serial.println("\nstatus=READY");
started=true;
}
else Serial.println("\nstatus=IDLE");
if(started){
//Enable this two lines if you want to send an SMS.
if (sms.SendSMS("+971505393365", "Arduino SMS"))
Serial.println("\nSMS sent OK");
}
};
void loop()
{
if(started){
//Read if there are messages on SIM card and print them.
if(gsm.readSMS(smsbuffer, 160, n, 20))
{
Serial.println(n);
Serial.println(smsbuffer);
}
delay(1000);
}
};
What mistake i did?
Please anyone reply me, tks..

The problem at 99% is in the communication between Arduino and Seed Studio.
This issues' page is dedicated to problems directly linked at library
developing and GSM GPRS Shield of Futura Shop / Open Electronics.
For other kind of requests I think that is better to ask on others Forum (e.g.
arduino.cc for Arduino boards)
