I hope I posted this is in the right subforum.

Hi everybody,
I'm trying to control my AC using Arduino. I have bought an IR transmitter and receiver.

I've been able to decode my remote control, it's using Samsung protocol.
I have been able to copy the signal, and send this signal to my receiver as a test which verified it was decoded correctly, but my AC doesn't react to it.


For those interested in the Arduino side of it, I've used IRremote to decode the signal, it prints:

Protocol=Samsung48 Address=0xB24D Command=0x3FD Raw-Data=0xFC03 48 bits LSB first
Send with: IrSender.sendSamsung48(0xB24D, 0x3FD, );

I have then sent the same signal using that command on the second line, with up to 10 repeats to no avail. Again, I have verified this signal using my receiver to make sure it is sending the correct code. Receiver prints:

Decoded protocol: Samsung48, decoded raw data: FC03, decoded address: B24D, decoded command: 3FD


Any help would be much appreciated! I really want to make this work.
