Broadcom WiFi/Bluetooth [Guide]

Hi,

Having trouble with bluetooth on my Asus laptop. Using the 20200480 BCM94352Z LENOVO WIRELESS MINI CARD (listed as 0489 e07a). Often, bluetooth will not load. When it does, after sleep it will show 'Not available', even though it is still listed in About this Mac. Followed all the Guides re install USB setup, etc.

Wifi aspects of the same card work fine.

I've attached the requested troubleshooting files. Hope someone can identify the issue!

Screenshot and IOReg show 2 bluetooth controllers, verify USB configuration

Thanks for the insight. I have discovered that if the bluetooth is recognized on boot, the IORegistry is normal and so is bluetooth behavior. However, after deep sleep and on battery power the bluetooth show 'Not available' and the IORegistry shows the double connection. I've attached the IORegistry which shows the sequence of normal wake up and (abnormal) deep wake-up.

?? I have delays in the Boot Args for the BT card - should I make them work for wake up as well???

Often when waking up with the 'Bluetooth not available', the laptop reboots and has the following error report:

Stackshot Reason: Wake transition timed out after 180 seconds while calling power state change callbacks. Suspected bundle: com.apple.iokit.IOUSBHostFamily. Thread 0x7020e.

What should I use to replace Intel® Wireless-AC 9560 on my Asus Zephyrus GM501GS? I'm using High Sierra 10.13.6 2019-001

I have an issue where my DW1820A is not working properly. I have 802.11A, but no 802.11AC connectivity, and while bluetooth technically works, it doesn't function properly (it won't actually complete a pairing session). I am running 10.13.6. Everything else works great. Debug is attached. Thanks for helping!

I have exactly same problems as you describe with this card, and it was working properly until recent dates. Something either in recent Lilu update or AirportBrcmFixup broke ac mode and bluetooth. Those are the only kext I've updated recently.

Need assistance. Installed this MiniPCI card as showing as a valid device. I am NOW getting WiFi - but BlueTooth is NOT working. The SYSTEM PREFS shows no BlueTooth is installed.

Any Ideas?
