Hi there, I'm also trying to make my DW1820A (model CN-08PKF4) work under Catalina. After following the advices here, my Wifi is working, but can't connect to bluetooth devices. Like many of you it seems. Is there any new advice/solution in Feb 2020? - My loaded BT firmware version is v7 c44689, although it looks like that BrcmPatchRAM is not able to connect to the device at boot time (see boot log bellow) - On the kext site, I'm using BrcmPatchRAM-2.5.1-RELEASE in S/L (BrcmBluetoothInjector.kext, BrcmFirmwareRepo.kext and BrcmPatchRAM3.kext). I also tried first the vanilla / boot injection first with clover (swapping BrcmFirmwareRepo.kext with BrcmFirmwareData.kext) but same result. - My device properties is as follows: <key>PciRoot(0x0)/Pci(0x1C,0x1)/Pci(0x0,0x0)</key> <dict> <key>AAPL,slot-name</key> <string>WLAN</string> <key>compatible</key> <string>pci14e4,4353</string> <key>device_type</key> <string>Airport Extreme</string> <key>model</key> <string>Dell DW1820 (BCM4350) 802.11ac wireless</string> <key>name</key> <string>Airport</string> <key>pci-aspm-default</key> <integer>0</integer> </dict> - My boot args are as follows: <key>Arguments</key> <string>kext-dev-mode=1 amfi_get_out_of_my_way=1 dart=0 -igfxnohdmi brcmfx-country=#a rtcfx_exclude=56-58 brcmfx-driver=1</string> - I didn't see any ASPM option to disable in my BIOS, but there is the pci-aspm-default/0 entry in clover. Is that enough? What's less clear to me: - I saw multiple advices on forums about checking USB? My System Informations says that BCM2045AO is "internal". Is that enough? - Is there anything else I can try? - The bluetooth part of the device never worked in Windows 10: it appears as "disconnect" from the system in the Device Explorer. So I was not able to upload the BT firmware via standard windows driver before rebooting in MacOS. Do you have any idea how to solve this under windows and what drivers did you use there?
