BlueToolFixup has known issues with macOS 12+

[dhinakg]

As detailed in #1669, Apple has been actively working on the Bluetooth stack in macOS Monterey. Recent betas have broken the approach BlueToolFixup used to enable Bluetooth for non-native Broadcom and Intel chipsets. There are several known issues:

• transport-encoding no longer works to change the transport type
  • Transport type is also dependent on SMBIOS in some cases (ref)
  • Even though it does not affect the transport type anymore, setting transport-encoding still has adverse effects for unknown reasons
    • Specifically seen to break power cycling BCM20702 (non-PatchRAM) on legacy Macs
• bluetoothd now has several checks that raise issues
  • With Beta 10, any vendor that is not Broadcom or CSR is ignored
  • Certain checks cause bluetoothd to take different codepaths which may or may not be supported for the specific chipset

If you are experiencing issues with Bluetooth on Monterey, please post here (do not create a separate issue) and make sure to include:

• your motherboard/laptop/Mac model
• the specific Bluetooth chipset you have
• an IOReg

Bluetooth is on but I can't send files to my iPhone, only receive. Handoff works only one side. iPhone -> Mac
My bluetooth card is not recognised like a Broadcom????
I have attached my ioreg and a screen of my Bluetooth section in System Information

Card is recognized as "THIRD_PARTY_DONGLE" as well and I experience the same restrictions as MaximeH38

Airdrop/Handoff works only one way (iPhone to Hack/Real Macbook to Hack), if i turn off bluetooth can't turn it back on untill I run " sudo killall -9 BlueTool bluetoothd " terminal comand or restart the hack.
From beta 10 i'm using new BlueToolFixup with the bypass vendor check patch.
Bluetooth Headphones connect and work.

Dell G5 5587 laptop using SMBIOS MacbookPro 15,3
Dw1820a and dw1560 never worked right
Before monterey beta10 system report showed this

AirDrop and Handoff only worked in one-way.
And on B10 with bypassed vendor BluetoolFixup

And they won’t connect to any Bluetooth devices.DW1560 can't even scan.
Both cards have USBPorts mapped

I never had issues and requirements for any (fixup) kexts but wake from sleep BT is down since 12.0b7 up to now.

Hi, I'm also experimenting issues with Bluetooth on macOS Monterey RC. I had no problems on Big Sur. My specs are:
MB: MSI Z490 Tomahawk
Bluetooth device: 0a5c:6412 / Dell DW1820A
Running on Monterey 12.0.1 (21A558).

I cannot enable bluetooth under System Preferences. It shows as disabled, but the enable button does nothing.

I forgot to thank you for your time and your work :)

EDIT: I was not loading BlueToolFixup properly. Now I got bluetooth working (using version 2.6.1). However, i'm having issues with AirDrop, Continuity and Sidecar.

In Monterey 12.0.1, my internal WiFi BT Card (Broadcom BCM94352HMB DW1550) is detected as dongle as well:

In Catalina it looks like this:

This is the Kextloading sequence and Min/Maxkernel Settings:

Now, if I boot Monterey, BT works. But as soon as I disable it, I can't re-enable it. I guess because it thinks the "dongle" has to be reconnected.

I can confirm that 2.6.1 works with the Monterey 12.0.1 release. However Airdrop from Hackintosh to iPhone does not work with my DW1560 card. But iPhone to Hackintosh works
