I am IR library from Ken Shirrif at https://github.com/z3t0/Arduino-IRremote/releases/download/MAJOR/IRremote.zip
It is good and I have used the examples to receive and send and to playback IR signals from the library. And they are working good.
To send Unknown signals we should use sendRaw() method with a list of integers got from the receiver.
My question is when I use the receive program, I get the decoded hexadecimal value for even the Unknown signals. And can I use this small decoded signal to send signals apart from the long list of integers.
I am trying to send these codes from android. It would be quite easy to send and store the small hexadecimal decoded value.
Is there a way to use the decoded value to send for raw signals with some encodings at arduino?
