I can guarantee that beo4 only works with Bang & Olufsen TVs normally, because of their high frequency 455 mhz.
This is why I had to buy a TSOP7000 which can receive those high frequencies.
Also the Beo4 remote works a split second after reboot, but then it stops to work. Something is wrong in the bootup script, when I change to the Projector. Maybe the projector is recognized as something else? Is the Raspberry received any information from the device connected to the HDMI port? Would I be able to compare what the Pi receives from the LG TV and from the projector?
Well nobody is objecting that. The question we had is if when connect to the TV the Beo4 controls the Pi via the TSOP or via CEC. So to first exclude that as the possibility I suggest you disable CEC when the Pi is connected to the TV and see if you still can controll the Pi via the Beo4.
Just be sure you have SSH access so you can revert back if you can not controll via Beo4 anymore.
Hi jb2cool, thanks for writing. No this is not a possibility. I’ve tried multiple options:
The Raspberry connected to my TV, while my projector pointing directly on the TSOP-chip. Result = The Beo4 remote works perfectly on the TV.
Changing the HDMI cable to a shorter one (1 meter) - Makes no difference.
Tried with irw, viewing if the Pi actually receives any signals from the Beo4 remote when connected to the projector. Result = Yes it receives signals, but only when I press multiple times fast on the button. Fx. if I want to navigate “Up” in OSMC, then I’ve to push the up button 4 times fast, sometimes it works, sometimes it doesn’t.
Not sure if I just have to accept that it only can work with the Kodi App from App Store. Would be great to control both the TV and the Projector with my Beo4 Remote…
Use TSOP4838 if possible. We used that for the first OSMC remote for Raspberry Pi and didn’t have any complaints with sensitivity.
Ultimately you need irw to pick up the presses properly.
I suspect you won’t have one at hand, but to diagnose I would scope the TSOP in a room where it works and in a room where it doesn’t and compare.
TV is hanging on the wall with the raspberry behind it. TSOP is able to either stay behind the tv or hang out, so it’s possible to have a great connection without having to send signals through the tv.
The projector only have 2 cables - power cable and hdmi to mini hdmi cable.
I don’t see why this makes any problems. HDMI shouldn’t make any difference between a TV as a monitor or the Projector as a monitor…
Unfortunately I have no further solutions.
I’d likely need to be in the room to see what the issue may be. All I can suggest is interchanging some peripherals and if you have a friend with good technical knowledge around to get them to take a look.
I’d also definitely rule out CEC as being the reason it works on the TV. If you load cec-client (with Kodi stopped) and pressing remote shows output, then it’s actually your TV doing the heavy lifting and perhaps IR was always problematic.
