Sending high frequency IR signals

[KasperSvendsen]

Hi,

I recently dropped by Bang & Olufsen Beolink 1000 on floor which it did not survive. I came up with the idea to use an Arduino to send IR signals in order to control my Bang & Olufsen stereo.

I got my self an IR LED for this project. I've installed the IRremote library and tried to mess around with it. I've read that the Bang & Olufsen systems send IR signals at 455 kHz which apparently is way beyond what other brands operate at.

I have tried doing some research but I couldn't find answers for two questions:

• How do I send a B&O IR code using my IR LED? (e.g. to turn my stereo on)
• Where can I find a list with the IR codes B&O uses for their systems? (I've found this but I don't know if it is any help: GitHub - christianlykke9/Beomote: Bang & Olufsen Remote Library for Arduino)

I hope one is able to answer my questions. Thanks in advance!

You may also need to match the IR wavelength being used by your device. Google led me to one merchant offering these LEDs: 810nm, 850nm and 940nm wavelength. Yours may be one of these or may be another wavelength, entirely.
