Apple Broadcom Built-In Bluetooth in Device Manager not showing

I’m unable to get any bluetooth devices to connect to my macbook pro 13 (2017) running windows 10. The bluetooth product & Vendor ID: VID: 0x05AC ---- PID: 0x007E

Here are the steps I’ve taken.

Downloaded the latest bootcamp drivers on Mac O/S side and ran a ‘repair install’ on windows using them. Rebooted. No change.
Windows device manager, under Bluetooth, “Apple Broadcom Built-in Bluetooth” does not show (even temporarily).
Bluetooth Radio > Allow this computer to turn off this device to save power > unchecked

Windows device manager, under Network Adapters, “Broadcom 802.11ac Network Adapter”. > advanced > Bluetooth Collaboration is not an option
Driver 7.77.119.0 ( have tried rolling back, this did not help.)
Allow this computer to turn off this device to save power > unchecked

This thread is very similar https://discussions.apple.com/thread/251394916 however the user appears to at least initially be able to connect the BT device, suggesting it was related to the power save feature. I am not even getting that far.

Any suggestions welcomed.

These two bullets are confusing...

Windows device manager, under Bluetooth, “Apple Broadcom Built-in Bluetooth” does not show (even temporarily). This implies you do not have a BT radio...
Bluetooth Radio > Allow this computer to turn off this device to save power > unchecked ...but this one says you have one.

0x05AC is the Apple Vendor ID. It is possible that Windows has installed a generic driver. Also, the 7.77.x.x drivers do not have BT collaboration, but the 7.35.x.x drivers do.

Also, see Bluetooth Driver for MBP 14,3 on bootcamp - Apple Community .

I was getting confused myself. I thought “Apple Broadcom Built-in Bluetooth” should show as well as the "Bluetooth Radio".

I've added some screen shots for clarity, I only have the bluetooth radio.

I have rolled back the driver to 7.35.x.x and I still do not see a BT collaboration on the advanced tab.

I'm trying to connect an orginal Bose Mini Bluetooth speaker and a cheap bluetooth mouse (both work on mac OS)

7.77.119.0 - Do not see either device.

7.35.118.83 - Do not see either device.

7.35.118.73 - See mouse but just hangs at connecting

7.35.118.68 - See mouse and bluetooth speaker but just hangs at connecting

I couldn't find where to download .40

Do you have a BT Radio in Windows Device Manager -> Bluetooth?

Unfortunately not, oh well it's not the end of the world, I'll just have to use a wired mouse! :)

EDIT

I had a look in BootCamp.xml and I see this:

<Name>Broadcom 802.11 Network Adapter Driver

<InfName>bcmwl6.inf</InfName>

<Provider>Broadcom</Provider>

<ServiceBinary>bcmwl5.sys</ServiceBinary>

should I try driver 5.106.199.1 ? (I don't see this is available in the list of drivers, so I'm not sure I even can).

.73 works very well. If you install it and enable Collaboration and disable Power Management, do you still see the same issue?

Also, you have 13-in MBP, not a Mini/iMac/MacPro. Unless you constantly use the MBP in clamshell mode, it makes me wonder if you need a BT mouse. I have used the .73 driver with an Apple MM2, and it works very well, in a very noisy 2.4GHz RF environment.
