My AC does not recognize if I send what I captured with IRremote

I mean --- looks like after the header, there are 8 bytes per setting, but not sure

There are several posts on our blog explaining the reverse engineering process and also on GitHub.
Our own AnalysIR application, provides several tools to help reverse engineering of AC signals.

Essentially the first 3 & last value in your capture are headers. The rest are bit fields of 0 & 1. The 1 or 0 is determined by the 2550 or 500.

Usually there is also a checksum - typically at the end. Our AnalysIR app also has a tool to detect the checksum.

I usually advise to forget reverse engineering hte bit fields and just capture the top 5 or 10 signals you would typically use (most people only use on, OFF and a few temperature/fan settings.
There are also several posts on our blog to send from flash & save SRAM.

Have fun & let us know how you get on

What does AnalysIR app do? What input does it take? and what does the output tell me?
I am a hobbyist in India (actually, a retired person). I keep doing all this experiments at home using microcontrollers (nano and esp) for my satisfaction
$20 is ~Rs.1670. can you give me some discount on that?
