I am sorry. Thanks.

After a bit of digging I found this line in dmesg right after bootup:

[IOBluetoothFamily][SearchForTransportEventTimeOutHandler] -- 'IOBluetoothUSBDFU.kext' is loaded causing this missing Blutooth Controller Transport problem

Is this relevant?

I also injected a USB SSDT and it still doesn't work.

BCM94352Z requirements:
WiFi: AirportBrcmFixup.kext + Lilu.kext
BT: BrcmPatchRAM2.kext + BrcmFirmwareRepo.kext

Note: BT assumes correctly configured USB (you have the link in your query).

No need of FakePCIID_Broadcom_WiFi.kext or BrcmFirmwareData.kext or any Clover patch listed on this guide?
And what's the meaning in AirportBrcmFixup Readme?

Installation types

• Clover Airport Fix + AirportBrcmFixup
• Clover Airport Fix + AddProperties(fake device-id) + AirportBrcmFixup (preferable)
• Clover Airport Fix + AirportBrcmFixup + FakePCIID + FakePCIID_Broadcom_WiFi.kext
• AirportBrcmFixup + FakePCIID + FakePCIID_Broadcom_WiFi.kext

Correct.

And what's the meaning in AirportBrcmFixup Readme?

Installation types

• Clover Airport Fix + AirportBrcmFixup
• Clover Airport Fix + AddProperties(fake device-id) + AirportBrcmFixup (preferable)
• Clover Airport Fix + AirportBrcmFixup + FakePCIID + FakePCIID_Broadcom_WiFi.kext
• AirportBrcmFixup + FakePCIID + FakePCIID_Broadcom_WiFi.kext

It is wrong.

I made the USB SSDT, I missed the fact that you can mark things as internal (I guess that could make a difference). Still no Bluetooth... I also tried

portType=2

instead of

UsbConnector=255

to no avail.

Uploading problem reporting files. Specs are:

• Mobo: Gigabyte Z370P D3
• CPU: i7-8700K
• GPU: Gigabyte Radeon™ RX VEGA 64 GAMING OC 8G
• WiFi/BT: BCM94360CD

I assume this from your kernel log has something to do with it:

2018-10-23 19:39:54.225180+0200 0x983      Default     0x0                  0      0    kernel: (IOBluetoothFamily) **** [IOBluetoothFamily][SearchForTransportEventTimeOutHandler] -- 'IOBluetoothUSBDFU.kext' is loaded causing this missing Blutooth Controller Transport problem

Firmware on the device not compatible, or not up-to-date with what the BT kexts want?
(I suspect 'FU' stands for 'firmware update').

I have working bluetooth with my BCM943602CS but sleep breaks it and I see this:

Reboot and bluetooth seems OK again till next sleep.

AFAIK USB is now configured correctly with help of Rehabman, can anyone help me with the BT issue now?

 

[WedgeTail]

I have a Dell DW1830 which provides Wi-Fi OOB, no kexts, but I have been unable to get Bluetooth to work. I seem to have an ongoing issue with SIP and kexts not loading in /L/E because they are 'unsigned'.
Have tried Rehabman's Brcm package without success, just as a casual idea I tried a years-old D-Link DBT-122 USB Bluetooth adapter and it worked straight away! Apparently it is Broadcom-based.

So I don't need to worry about the DW1830.

 

[hameerabbasi]

Is there a solution or guide somewhere for how to fix this? I even replaced the entire card, still doesn't want to work. The second one is from a real MBP according to the seller. Maybe I need to replace the PCIe casing for it?

Edit: I tried manually grabbing the firmware and flashing it using dfu-util on macOS:

$ sudo ./dfu-util 05ac 828d 20702_828D.dfu
dfu-util, utility to flash dfu firmware into USB devices on OS X.
Based on original dfu-tool & dfu-programmer for Linux.

Edit: Getting the firmware from macOS and flashing that firmware in Ubuntu worked. Now BT is working.
