Boas,
instalei uma biblioteca para o sim900, "gsm-gprs-gps-shield".
no caso seguinte recebo uma sms e é apresentado o numero e o conteúdo no serial monitor.
#include "SIM900.h"
#include <SoftwareSerial.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 or slower.
if (gsm.begin(2400)) {
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("3471234567", "Arduino SMS"))
//Serial.println("\nSMS sent OK");
//}
};
void loop()
{
if(started) {
//Read if there are messages on SIM card and print them.
/** deprecated method
if(gsm.readSMS(smsbuffer, 160, n, 20)) {
Serial.println(n);
Serial.println(smsbuffer);
}
**/
//get 1st sms
sms.GetSMS(1,n,20,smsbuffer,160);
Serial.println(n);
Serial.println(smsbuffer);
delay(3000);
}
};
o que necessito é fazer uma ação caso o numero e o conteúdo seja o que eu quero.
ja igualei o smsbuffer a uma string e envio o que esta nessa string e nao funciona.
opinioes?
