I recently upgraded my Dell Inspiron 15 7559 to Windows 11, despite Dell stating that this laptop isn't supported for the upgrade. While I've found most of the necessary drivers from the original manufacturers' websites, I'm still struggling with finding the right driver for the Bluetooth chipset. Any suggestions on where to look or if it's possible to use existing drivers?

Have you tried using the drivers provided by Dell? Sometimes they work better than expected, even if they're marked for Windows 10. I upgraded and didn’t have issues using those drivers on my Lenovo.
Both Windows 10 and 11 use the same driver model, so the drivers should, in theory, work without issues. Have you considered that?
Yeah, but I haven't had great luck with Windows 10 drivers. Finding the original chip manufacturer's drivers has worked much better for me compared to Dell's specific ones.

I did try them, but they were rejected by the OS or caused weird issues like shutting off randomly. When I found drivers for Windows 11 from original manufacturers, they've worked much better for me.
