            @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 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"

                          @rafitc99 I changed the buffer and that solved the problem. Thanks a lot for coming to my rescue.

                          @salmanfaris I did change the buffer size and everything is working perfectly. Thanks coming to my rescue.

                          I am using the hardware serial (pin 0 and 1 on Arduino Uno)

                          As @rafitc99 mentioned, you need to expand the Serila buffer, in the hardware serial also the Arduino board package implements a 64-byte ring buffer for send and receive on the hardware serial messages. So you need to change that to 256 as per your message length.

                          @rafitc99 The thing is that I am not using the SoftwareSerial library in receiving the message from the first microcontroller. I am using the hardware serial (pin 0 and 1 on Arduino Uno)
