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
