Difference between IR code that i receive with my sending code

Projects Networking, Protocols, and Devices

Hello. Thank you for your help in my previous post.

I work with IR to replace TV's remote with my arduino.

First, I record my remote frequency with this sketch :

#include <IRremote.h>
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
decode_results results;
void setup() {
  Serial.begin(9600);
  irrecv.enableIRIn(); // Start the receiver
}
// Dumps out the decode_results structure.
// Call this after IRrecv::decode()
// void * to work around compiler issue
//void dump(void *v)
//{  decode_results *results = (decode_results *)v
void dump(decode_results *results)
{ 
  int count = results->rawlen;
  if (results->decode_type == UNKNOWN)
  { 
    Serial.print("Unknown encoding: ");
  }
  else if (results->decode_type == NEC)
  { 
    Serial.print("Decoded NEC: ");
  } else if (results->decode_type == SONY)
  { 
    Serial.print("Decoded SONY: ");
  }
  else if (results->decode_type == RC5)
  { 
    Serial.print("Decoded RC5: "); 
  }
  else if (results->decode_type == RC6)
  { 
    Serial.print("Decoded RC6: "); 
  }
  else if (results->decode_type == PANASONIC)
  { 
    Serial.print("Decoded PANASONIC – Address: ");
    Serial.print(results->panasonicAddress,HEX);
    Serial.print(" Value: "); 
  }
  else if (results->decode_type == JVC)
  { 
    Serial.print("Decoded JVC: "); 
  }
  Serial.print(results->value, HEX);
  Serial.print(" (");
  Serial.print(results->bits, DEC);
  Serial.println(" bits)");
  Serial.print("Raw (");
  Serial.print(count, DEC);
  Serial.print("): ");
  for (int i = 0; i < count; i++)
  { 
    if ((i % 2) == 1)
    { 
      Serial.print(results->rawbuf[i]*USECPERTICK, DEC); }
    else
    { 
      Serial.print(-(int)results->rawbuf[i]*USECPERTICK, DEC); 
    }
  Serial.print(" "); }
  Serial.println(""); 
}
void loop()
{
  if (irrecv.decode(&results))
  {
    Serial.println(results.value, HEX);
    dump(&results);
    irrecv.resume(); // Receive the next value
  }
}

And then i copying it to my sending sketch :

#include <IRremote.h>
IRsend ir;
int estado=0;
char dato;

The problem is when I sending the IR frequency i got the different code with my remote frequency. I need to repeat it two until eight times to get the same code. Can someone help me?

What IR receiver are you using...model# ...link?

How have you the IR emitter wired up...circuit?

Try recording the signals using the script on this page and post the results here & I will have a look.

...it will give much more accurate timings.

TIP: a good way to use sendRaw is:

unsigned int pwrTv[]={4600,4350,700,1550,650,1550,650,1600,650,450,650,450,650,450,650,450,700,400,700,1550,650,1550,650,1600,650,450,650,450,650,450,700,450,650,450,650,450,650,1550,700,450,650,450,650,450,650,450,650,450,700,400,650,1600,650,450,650,1550,650,1600,650,1550,650,1550,700,1550,650,1550,650}; 
//note the array above has no size between the []...avoids making a mistake with sizes etc

ir.sendRaw(pwrTv,sizeof(pwrTv)/sizeof(pwrTv[0]),38);

i used PIC120435 in this pict https://arduino-info.wikispaces.com/file/view/IR-Receivers-900.jpg/473330184/800x225/IR-Receivers-900.jpg

and i connect it to the DI11, GND, and 5V.

Not only when i send raw code, but the nec's too.

Do you know the problem and how to solve it?
