The Hex codes , which i receive is the same everytime.  smiley  but the raw data varies ..

 

Now How should  I will write the irsend to send this code for the air conditioner?

    The data stream you are seeing is actually the microseconds of the carrier, this will vary a bit due to the software timing of the ir.

     

    All you need to do is take the average of each pulse in order to simplify the replay

     

    If you want more info, the best place to look is the code for the or library, the timing will all be there

    here is a sample from a library I am modifying

     

    // pulse parameters in usec

    #define NEC_HDR_MARK 9000

    #define NEC_HDR_SPACE 4500

    #define NEC_BIT_MARK 560

    #define NEC_ONE_SPACE 1600

    Hello Peter ,

                               May i know what library you are referring and then how about this way ?

     

    unsigned int Signal_0_0[] = {3750,1850,500,400,500,1350,550,400,500,1350,500,450,500,1350,550,400,500,1350,500,450,500,1350,500,450,500,1350,500,1350,500,450,500,1350,500,450,500,1350,500,1400,450,1400,500,1350,500,450,500,400,500,1400,450,1400,500,450,500,400,550,400,500,450,500,1350,500,400,550,400,500,450,500,400,500,450,500,450,450,1400,500,450,450,450,500,450,500,450,450,1400,500,400,500,450,500,450,500,1350,500,450,500,400,500,450,500,1350,550,400,500,400,550,400,500,450,450,1400,500,450,450,450,550,400,500,450,500,400,500,450,500,400,500,450,500,450,500,400,550,400,500,450,500,400,550,1350,500,400,500,450,500,400,550,400,500,450,500,400,500,450,500,450,450,450,550,400,500,400,500,1400,500,450,500,400,500,450,500,400,500,450,500,450,500,400,500,450,500,450,450,450,550,1300,500,450,500,1350,500,1400,450,1400,500,1350,500,1400,500,400,550,400,500,450,500,400,500,450,500,1350,500,1350,500,1000};

     

    int khz=38;

     

    void setup()

    {

      Serial.begin(9600);

    }

     

    void loop() {

     

             if (Serial.read() == '0') {

             Serial.println("Transmitting");

             for (int i = 0; i < 3; i++)

             {

             irsend.sendRaw(Signal_0_0, sizeof(Signal_0_0)/sizeof(int), khz);

             delay(40);

             }

      }

    }

    sorry for the delay, yes without testing it looks like that should work
