Hi,

The BS4000 will be native to the Beo4. No programming is necessary. I’m not sure what the problem is but the first thing to do is to check the BEo4 has good batteries and is in the correct Audio Option (the remote does nothave an option but it programmes the beo device to a remote command level;- option 0 to 6.

You need to read the Beo4 manual and press a sequence of buttons to place the remote in the right option. Audio option 1 (if standalone there is no beovision), option 2 if there is. I suspect the BS4000 may be in option 0 (slave).

However, I am unsure what will happen with your programming app? Although the beo4 remote has not changed because it cannot be programmed, the reception of commands may be double as the beo4 does not really distinguish a difference in emitted pulses. However, the Beo-devices do.

For instance, for a beovision with Masterlink connection to the BS4000, the TV would be in (option 2: video single master on). The BS4000 (option 0: audio slave off). Now when you press volume up, listening to the audio source only, the BV knows not to respond but to relay the command to the BS4000. Without that Audio/Viideo option setting and the Masterlink umbilical,  the remote would send the command once, but it would be received twice; one for each device.

so it’s complicated with what you have done.

Most IR remote controllers use 38 kHz as their carrier frequency, whereas B&O use 455 kHz. It is unlikely that a third party IR device will receive or transmit at the higher B&O frequency, hence I suspect that you will be unable to get it to work.

Guy is right, your phone is very unlikely to have an IR emitter suitable to learn or send B&O IR codes. Do you know if the app can import Pronto Hex codes? If it can, there are some B&O codes on the LIRC page here

There are codes there that imitate the BEO4 you can try but it may not work.

Good luck

No, the point is not to get the *phone* to send or receive 455kHz IR codes, it's to get that unknown-brand IR controller to do so.  Tuya is a cloud platform service provider.  They make developing "smart" hardware easier (supposedly).  Contact the purveyor of that IR box, and @Guy's answer is what you need to ask them.

Or, if you're just an end-user looking to control your system, try a (used, NLA) Logitech Harmony hub:  Though it cannot receive 455kHz codes, it *can* transmit them, and has a library of pre-programmed buttons for the B&O IR devices.  (Although Logitech no longer sells them, they still maintain the back-end computer allowing you to add/delete devices from your hub.)

My understanding of the OPs original question is clearler now. The first part of my answer is still valid. Verify Beo4 commands by making the BS4000 operate with it. This is A.Option setting to 1 or 2

I think the OP is trying to map a number of remotes to an App and a generic (all frequencies one hopes?) IR blaster.

As a bit of background info as many of you may know, my main critical listening system is the Auralic G2 system. It has a neat internal feature where it can learn ANY remote. Simply select the control you want - say Play, and then repeatedly press the button on the remote you want to assign to that "Play". I have done this on BR-Essence, BR1 (both in IR mode) and Beo4.

BUT.......

There is something about the B&O codes which confuses it? Turning the wheel on the Essence for volume up, say, and you get a programme for >> (FWD). When trying other commands, they duplicate store in the Auralic, and not the command you intended. So I don't think this is about transmit/receive at 455kHz or 38kHz, but the breakdown of commands thereafter.

Good luck to OP regardless. I hope he posts about his success or failure for the knowledge base

 

Thanks all! That's correct, there is an app on my phone (Tuya) that can link to a device (IR blaster) that sends IR signals to the respective device.

I can see that my IR blaster is in fact running on 38kHz. I wish i bought the slightly more expensive model that also suppots 455kHz. Anyway I will buy that in the future and try, and report back, thanks all!

Hi @mojofml - may I ask where you found the “more expensive IR blaster that supported 455khz?” Ideally a Tuya compatible one

I’m looking to add my B&O tv to my home automation - but can’t find a suitable IR blaster. Wondering if I can avoid building my own using a raspberry pi and some IR leds and LIRC!

thanks

(EDIT: turns out you can only program it with dealer software, RIP)

Not directly related but this is potentially one option https://www.rticontrol.com/xp-3-control-processor.html

A bit pricey new but there's some used ones floating around on EBay, IR frequency range is 15-460 khz so would probably work.

 

Other possibility use a Global Cache interface
