Researches

Wi-Fi

Without AirportBrcmFixup.kext

DW1820A's Wi-Fi works OOB.

DW1820A's device ID 14e4:43a3 was included in IO80211Family.kext, and there's no need to fake it into any card else in Clover's device tab.

Sysinf will show Third-Party Wireless Card.

With AirportBrcmFixup.kext

Still no need to fake devide ID.

Sysinf will show AirPort Extreme (0x14E4, 0x23).

Firmware Version says Firmware Version: Broadcom BCM43xx 1.0 (7.77.61.2 AirPortDriverBrcmNIC-1305.8)

Bluetooth

Release firmware.

DW1820A's bluetooth module requires firmware uploading(RAMUSB).

By shutting down the system ( maybe also disconnect the power supply ), and waiting long enough (likely 5 minutes), the uploaded firmware will be released.

If we enter macOS now, without a bluetooth firmware uploader(BrcmFirmwareData.kext or BrcmFirmwareRepo.kext), the bluetooth won't work, and the firmware version will be 4096.

Upload firmware via macOS

I havn't firgure out how to upload firmware via macOS correctly.

Using original BrcmFirmwareData.kext or BrcmFirmwareRepo.kext, I did see the bluetooth changed into version 5799 ( meaning firmware was uploaded ), but bluetooth won't work. It's hard to connect to bluetooth devices, and devices will keep disconnecting.

I thought it might be the firmware in the original kext being too old, so I tried recompiling the kext with firmware extracted from newest driver. The version changed into 4689, but still bluetooth was not working correctly.

And if I reboot into windows after this incorrect uploading, the device manager will told me that DW1820A was not correctly configured. I have to release the firmware first.

Upload firmware via Windows

The incorrect firmware must be released first, otherwise DW1820A will enter a weird state, as mentioned above.

Currently I'm uploading the firmware with Windows, using driver downloaded from DELL, firmware version 4689.

After uploading, rebooting into macOS with only modified BrcmNonPatchRAM2.kext placed inside clover/kexts/other, the bluetooth will work. Although the manual metioned it still depends on BrcmPatchRam2.

Someone mentioned he could upload the firmware via Windows in virtual machine. That should be able to save some rebooting.

You can’t perform that action at this time.
