Controlling Air conditioning Electrolux - irRemote problem

Other Hardware Home Automation
1

Dear,
I'm having some trouble to get a connection to an Electrolux air conditioner, model pi09f. I am using the IRremote's library and i can connect several devices, except the air conditioner.
Using the receive mode from the library I get the following codes by pressing the power button in the remote control for 2 times (I believe one code is for turning on and the other for turning off):

I removed the commas, the first group of numbers and the spaces between those groups from the original code.

I used the code as below:

unsigned int S_pwr3[100]={4500,4150,700,1450,700,400,650,1500,650,1500,650,450,650,400,650,1500,700,400,650,450,650,1500,650,450,650,450,600,1500,650,1500,650,450,650,1500,650,450,650,450,600,1550,600,1550,600,1550,600,1550,600,1550,650,1500,650,1500,650,1550,600,450,600,500,600,500,600,450,600,500,600,500,600,450,600,1550,600,1550,650,450,600,500,600,500,600,450,600,500,600,1550,600,500,600,450,600,1550,600,1550,650,1550,600,1550,600,1550,600};
   unsigned int S_pwr4[100]={4500,4150,700,1450,700,400,650,1500,650,1500,650,450,650,450,650,1450,700,450,600,450,650,1500,650,450,650,450,600,1500,650,1550,650,450,600,1500,650,500,600,1500,650,1500,650,1500,650,1500,650,500,600,1500,650,1500,650,1500,650,500,600,500,600,450,600,500,600,1500,650,500,600,450,600,1550,600,1550,600,1550,600,500,600,500,600,500,550,500,600,500,600,500,550,500,600,500,600,1500,650,1500,650,1550,600,1550,600,1550,600};

irsend.sendRaw (S_pwr3, 100, 38);
delay (10000);
irsend.sendRaw (S_pwr4, 100, 38);

also tried:

irsend.sendRaw (S_pwr3, 100, 36);
delay (10000);
irsend.sendRaw (S_pwr4, 100, 36);

I have searched in Arduino's forum but i found nothing.

Can someone help me?

you are hitting the size limit of RAWBUF within IRremote.(defaults to 100)

You can look for it in one of the library files and change it to 220 and try that out.

Otherwise, search for 'IRremote rawbuf' in this forum or via google and you will find instructions.

Hello rss10

Were you able to find a solution for this? I'm facing the same issue...
I have the same air conditioner model as you, and I can't control it.
TVs and other gadgets works fine...

Thank you

I was having the same issue using IRremote, after lots of research and experimentation I've found that my Electrolux uses the same protocol as "Midea". The project below has support to control it:
