i have arduino uno r3, a gsm shield ce0700, and a 4x4 kepad..i got the output for make voicecall..i also connected keypad with arduino and i was getting inputs to the serial moniter..but now i have to connect the gsm shield with the arduino and the keypad to gsm shield so that i can enter the phone num from the keypad and there will be definite keys to call and cut a call on the keypad like 'A','B'...please help me with the code..thanks in advance for reading.. :slight_smile:

i am trying to interface a 4x4 keypad to gsm shield ce0700 and inturn interfacing the gsm to arduino uno r3...so i used both gsm and keypad library..i want to give iputs from keypad such that num and i want to use particular buttons like A,B to call and hang call...but i am getting error on code..

while compiling i get this error

Looks pretty obvious to me.

Please use code tags when posting code.

please let me know some solution AWOL as i am very new in arduino

Both libraries contain a constant named IDLE and they are conflicting. You can't use those two libraries together unless you resolve the conflict. One way to resolve it would be to edit the source for one of the libraries and change all references to IDLE to some other unique name.

i think the "IDLE" isuue has been resolved..thanks for that..i changed one of the source idle..now i am getting a new error

OK thanks for letting us know.

please help me with the code..

// You put some stuff here
void setup()
{
   // You put some stuff here
}

void loop()
{
   // You put some stuff here
}

You'll need to provide a LOT more details about what YOU have done, and what sketches you have working INDIVIDUALLY in order to get more help.

i apologise for not giving enouh information..this is the code i am using..i have to connect the 4x4 keypad to gsm ce700 and in turn connect the gsm to aurdino..so that i can give inputs like phone num and can use particular keys for hang call and call..

this is the code i am using and i am geting this error
