Help needed: Arduino Wireless Notice Board project

[salmanfaris]

@rafitc99 , @SAFVAN did you tried the @arunksoman suggestion?

[SAFVAN]

Now message is displaying with mobile number, date, time.
I want filter the actual message only.

[salmanfaris]

@SAFVAN what was the solution with the previous problem?

[rafitc99]

@salmanfaris tried @arunksoman suggestion , c_str() instead to_charArray().. But want to parse SMS body only. Now working on that.

@rafitc99 what is the final code? Could you please share it with us? I have been battling with a similar project.

Which Arduino board did you use?

thanks

@codelery You can use any Arduino board. So far as i remember, we used Arduino UNO.

Somehow i found the code in my gist. It was a 3 year old project. So, i don't remember most of the things

Code:

#include <SoftwareSerial.h>
#include <SPI.h>
#include <DMD.h>
#include <TimerOne.h>
#include "SystemFont5x7.h"
#include "Arial_black_16.h"

#define ROW 1
#define COLUMN 1
#define FONT Arial_Black_16

DMD led_module(ROW, COLUMN);

String st;
const char *msg;
unsigned int LengMsg;
char finalMsg[100] = "";
SoftwareSerial mySerial(3, 2);

void scan_module() {
  led_module.scanDisplayBySPI();
}

void setup() {
  Timer1.initialize(2000);
  Timer1.attachInterrupt(scan_module);
  led_module.clearScreen( true );

  Serial.begin(9600);
  mySerial.begin(9600);
  Serial.println("Starting...");
  delay(1000);
  mySerial.println("AT");
  updateSerial();
  mySerial.println("AT+CMGF=1");
  updateSerial();
  mySerial.println("AT+CNMI=1,2,0,0,0");
  updateSerial();
}

void loop() {
  //  pollSms();
  displayMessage();
  delay(500);

  //Start print in led matrix
  led_module.selectFont(FONT);
  led_module.drawMarquee(finalMsg, LengMsg, (32 * ROW), 0);
  long start = millis();
  long timming = start;
  boolean flag = false;
  while (!flag) {
    if ((timming + 20) < millis()) {
      flag = led_module.stepMarquee(-1, 0);
      timming = millis();
    }
  }
}

//------GSM Helper

void displayMessage()
{
  delay(500);
  String msg = "";
  int start = 0, endPoint = 0;
  finalMsg[100] = "";
  while (Serial.available())
  {
    mySerial.write(Serial.read());//Forward what Serial received to Software Serial Port
    //     parseData(mySerial.readString());//Calls the parseData function to parse SMS
  }
  while (mySerial.available())
  {
    msg = mySerial.readString();//Forward what Software Serial received to Serial Port
  }

  if (msg.length() > 1) {
    start = msg.indexOf('*') + 1;
    endPoint = msg.indexOf('#') - 1;
    int count = 0;
    if (start > 1 && endPoint > 1) {
      strcpy( finalMsg, "");

      for (int i = start; i <= endPoint; i++) {
        finalMsg[count] = msg[i];
        count++;
      }
      Serial.println("SMS Received: ");
      Serial.println(finalMsg);
      LengMsg = count;
    }
    else{
      return false;
    }
  }
}

void updateSerial()
{
  delay(500);
  while (Serial.available())
  {
    mySerial.write(Serial.read());//Forward what Serial received to Software Serial Port
  }
  while (mySerial.available())
  {
    Serial.write(mySerial.read());//Forward what Software Serial received to Serial Port
  }
}

NB: The sms body should be between start and hash
Eg: * Hello Makers! #

@rafitc99 thank you so much. I will try it out and see if it will work.

@rafitc99 I tried this code, but the SMS is always corrupted. I got "Hello peopl⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮⸮
"

instead of "Hello people of the village who work day and night to make sure all is well"

@codelery Could you please share your code for checking?
