Okay, it's been almost a week, and no replies, lot's of lookers, does anyone from Studio 397 look at these support forums?
It's been much longer since this thread was created (which you also posted in recently). None of us (users) can answer you, so we didn't. Devs do read these forums, but that doesn't mean they'll reply to everything. The good news is they haven't replied and said no. As I said in that other thread, it'll probably happen one day, but who knows when.
I'm struggling with the same issue. I know that there is a telemetry tool that supports UDP data transfer to the wheel, but man it's 2023 and there is still no official support. Official support is the way to go, I'm not willing to download a third party tool to fix something that should be included in the sim itself. Would be great to cycle through the pages as you can in the MFD/HUD and just have the LEDs working like you'd expect.
