IR for A/C

Hi,

My project is an IR receiver and transmitter. After pressing a button it will learn an IR code, store it in USB. Then, it will retransmit it.

It works really good. Test it with multiple devices and works fine. Also with multiple air conditiones works with no problem, but there is a specific brand of air conditioner that will not do the job. It reads the code, send it, but A/C will do nothing.

My question is if any one knows about A/C codes. May be works in different frecuency? (not 38Khz). Any idea of what to test? I am out of ideas.

To receive and transmit I use the examples from Ken Shirriff, using SendRaw.

Thanks for any hints

Search for "IR raw".

This records the actual pulse times and replays the timed pulses as received.

Surprised AnalysIR hasn't caught wind of this yet, so...

Delta_G:
You kinda left out some crucial details there. Don't you think the particular brand that isn't working might help in figuring out what is different about that one brand? Don't you think the specifics of the code you're using would help diagnose the problem?

Hi
Thanks for answering.
The brand is DAGOR... I think is an OEM A/C. Other unknown brands work fine.

Code:
as stated, is the basic examples from Ken Shirriff, using SendRaw. (IRremote.h).
This is for sending:

unsigned int raw1[100] = {4850,3950,700,1500,650,400,650,1550,650,1500,700,400,700,400,650,1500,650,450,650,450,650,1500,650,450,650,450,650,1500,700,1500,650,400,650,1550,650,450,650,400,700,1500,650,1500,650,1550,650,1500,700,1500,650,1500,700,1500,650,1500,650,450,650,450,650,400,700,400,700,400,650,450,650,1500,700,1500,650,400,650,1550,650,450,650,400,650,450,650,450,650,450,650,400,650,1550,650,400,700,1500,650,1500,650,1550,650,1500,700,};
irsend.sendRaw(raw,100,38);

Thanks for the answer.
My project is able to transmit a signal of a lenght of at least 212 (my A/C has that signal).
The brand that doesn't work has a signial of 100.
