Arduino and GSM Module SIM900D serial communication

[gumimo]

  pa help naman po yung codes ng Arduino para ma read ang messages na nasa GSM module. Gusto po namin i monitor yung mga narereceive na characters via the serial monitor of Arduino software. any solutions or suggestions po please. kelangan po namin mapagana 2 before the year ends. salamat po admins

ano alam nyo sa arduino? Blinking LED? Reading UART(serial) using hyperterminal?

sa sim900? have you read the manual? do you understand AT Commands?

[gumimo]

di rin po ako makapagtest sa hyperterminal kasi windows7 gamit ko. kelangan lang po i place ang codes na to sa arduino:

AT+CMGL="ALL"
AT+CMGR=1

tapos gusto ko pong basahin ung messages sa serial monitor. ganito po ba?

#include <SoftwareSerial.h>

int rxPin = 0;
int txPin = 1;

// set up a new serial port
SoftwareSerial serial=SoftwareSerial(rxPin,txPin);

void setup()  {
  pinMode(rxPin, INPUT);
  pinMode(txPin, OUTPUT);

  // set the data rate for the SoftwareSerial port
  serial.begin(19200);

  // Set SMS to text mode. Note it is critical
  // to use \r\n to end each line
  // The delays are also critical, without them,
  // you may lose some of the
  // characters of your message

  serial.print("AT\r\n");
  delay(10000);
  serial.print("AT+CMGF=1\r\n");
  delay(10000);
  serial.print("AT+CMGR=1");
  delay(10000);

  // End the SMS with a control-z
  serial.print(0x1A,BYTE);
 
  char val = serial.read(); // get characters
  serial.println(val); //display characters
 
}

void loop() {
}

nasubukan mo na po ba tong code mo sir?

di rin po ako makapagtest sa hyperterminal kasi windows7 gamit ko.

Pwedi mo magamit ang hyperterminal using windows 7. Copy mo lang yung "hypertrm.dll" at "hypertrm.exe" galing sa PC with XP OS at ilagay mo sa isang folder. Of course meron dn mga 3rd party serial terminal like yung ka master gigz ba yun sa phil robotics.

sinubukan ko code mo sir, hindi nia nababsa ung message instead na pri2nt lang sa serial monitor ung:

AT+CMGF=1
at
AT+CMGR=1

sir glut! pde pong magpatulong?? dian po sa posted codes above.. anu po sa tingn nio ang mali? cnubukan ko po kasi xa pero un ang nalabas.. help naman po...
