Same here, on Venue 8 Pro.
Actually, the protocol Windows is using is H4, nevertheless, it doesn't work
also.
This snippet from DSDT table (BTH0 entry, DLAC3002) specifies the UART settings
that Windows (supposedly) uses:
UartSerialBus (0x0001C200, DataBitsEight, StopBitsOne, 0xC0, LittleEndian,
ParityTypeNone, FlowControlHardware, 0x0020, 0x0020, "\\_SB.URT1", 0x00,
ResourceConsumer, ,)
URT1 is /dev/ttyS4 in my config, the interesting thing is that there's no bytes
inbound at all - looks like the BT module is simply unpowered, no matter if I
attach an rfkill-gpio (like Jin above), or drive GPIOs manually (via
/sys/bus/gpio).
So, it's unlikely a kernel bug (and may be closed as such).

Jin. had you ever succeed in getting this piece working?

Same here, not working on Venue 8 Pro. Adding the ACPI ID doesn't result in
anything.

Forgot to mention, this was tested on kernel 4.4.

Has anyone been able to resolve this issue? I installed Ubuntu 2022 LTR but I
yet have the same issue with both WiFi and Bluetooth.

I would be okay with WiFi not working if I could at least get Bluetooth working
without using a dongle. That way I could attach my tablet to a Keyboard case
and use it for notes etc.

Puh, that is an old issue, and no attachments. Please attach the output of
`dmesg` and all other things asked for if you create a new issue in
https://github.com/bluez/bluez/issues.
