RC5 possible issue

[axwell]

Hello, i have attached an IR LED (http://goo.gl/m9HZkR) to my ESP module. I am tring to control my tv from internet sending RC5 signals. (read RC5 and codes with an receiver) TV accepts the IR signal only after 10-15 tries. Read somewhere that RC5 is very sensitive to timing.

Do you have any idea why ?

Thanks.

Hello,

can you try it with a normal arduino and the original library?

You may also try to change the constants RC5_T1 and RC5_RPT_LENGTH in IRremoteInt.h to get better results. I would start with decreasing their value a bit, but I'm not 100% sure.

Tested with arduino uno and original library works fine. EDIT: Hmm seems like one buton of the remote has 2 values. EX: power on / off - 2060 and 12 if i alternate these it works !

Do you have any idea why 1 button has 2 codes ?

Wow, that's kind a new for me, and no, sorry, I have no idea why it has two codes. Does it work if you send both codes after each other?

That is how RC5 works. You need to put toggle bit into code to send it... That is how I implemented it:

else if (type_json == RC5 || type_json == RC6) {  //Implementation of sending RC5/RC6 codes

    // Flip the toggle bit for a new button press
    if (repeat) {
      toggle = 1 - toggle;
    }

    // Put the toggle bit into the code to send
    codeValue_json = codeValue_json & ~(1 << (bits_json - 1));
    codeValue_json = codeValue_json | (toggle << (bits_json - 1));
    if (type_json == RC5) {
#if DEBUG
      Serial.print("Sent RC5 ");
      Serial.println(codeValue_json, HEX);
#endif
      irsend.sendRC5(codeValue_json, bits_json);
    }
    else {
      irsend.sendRC6(codeValue_json, bits_json);
#if DEBUG
      Serial.print("Sent RC6 ");
      Serial.println(codeValue_json, HEX);
#endif
    }
  }

I also store last code value to check if it is the same as new value. If it is I set repeat to 1.

Wow nice. If you think it's better than the actual one in the library, you are more than welcome to issue a pull request :)

This is something that is implemented in executing sketch, not in library. In official library there is also example that shows how to implement it. Here it is: https://github.com/z3t0/Arduino-IRremote/blob/master/examples/IRrecord/IRrecord.ino
