[Solved] A/C Lennox on/off with IR

Other Hardware Home Automation
1

Hi everyone, here its the thing:

I'm trying to control the ON/OFF of an AC brand lennox (never heard of this brand) by IR, it is the only thing I require at this time.
Researching online, I found two libraries that are responsible for this, they are IRemote and IRLib, i read their examples, despite
both libraries seem easy to use at first glance, this AC it's not support it,

I upload the arduino sketch IRrecvdump from both libraries and pressing the button to turn on / off this is what I got

For now I have no physical access to the AC, so I can not make yet another dump by pressing the on/off button, but I would like to have at least a test code to start discarding possibilities.

I never used these libraries before so i really don't know how to use them, the only thing that i know it's that they have a function call sendRaw, that it's used when you don't know the encoding used in the device, but i haven't find any example of it's use in the libraries.

If anyone can help me with this, it would be awesome.

I have the same problem! and the same air conditioning

I used this sketch from analyIR:

i have this output:

And IT WORKED... at the first attempt. i use IRLib IRLib | CY's Tech Talk but before use it, you need to go into the library and modify the archive IRLib.h, this specific line

 #define RAWBUF 100 // Length of raw duration buffer

And change it for a value over 200, i use 230

 #define RAWBUF 230 // Length of raw duration buffer

And that's it... Use it and tell me how it went

P.S. the code can be smaller, because the stream send by the remote it's not actually on/off, what it does, it toggle's the power's state os the AC , so if the AC its ON, you can send any of the raw signals and it will go OFF, same thing happend if the AC its OFF.
