can't 'resend' a decoded signal #34

Hi, I'm just starting using IRLib2 and wan't to emulate a remote (like most of users i presume). I managed to decode some ir signals from my remote (ONKYO TX-SR508) with the IRrecv class. Could not manage to get results with IRRecvPCI. Here's the serial output :


Decoded NEC(1): Value:4B36D32C Adrs:0 (32 bits) 
Raw samples(68): Gap:18474

32:m550

I tried then to emit this same code with the IRsendNEC but the device didn't respond. I got a control LED on a receiver so i know some code is emitted. Seems to be the wrong format even if i filled the send function with the values obtained with the receiver.

IRsendNEC necSender;
necSender.send(0x4b36d32c, 32);

Any idea where i did wrong ? Thx. Boimb.

Keep in mind that the PCI receive class only works on particular hardware pins.

Do you have 2 Arduinos where one is transmitting and the others receiving? What does the receiving Arduino see when you try to transmit? Some digital cameras such as WebCams can see an IR LED blinking. See if you can see anything coming out.

Thx for that quick reply.

K. I'll take a closer look at the (really nice) doc. As i got results with the IRrecv class, i didn't pay more attention. Is it a big deal not to use IRrecvPCI ?

I have only 1 Arduino board, but as i said, i got an IrReceiver linked to a control led so I can check if IR is emitted... and it's blinking. So i presume code is emitted. Feels like the "protocol" or "encoding" is not the right one. I've tried with raw too, and same thing... Control LED blinking, but device doesn't "understand" emitted code. I've read a similar issue here about Sony device. The device only responds if code is sent multiple times and at a specific frequency. Don't u think something similar could happen with ONKYOs ? Cheers.
