Hey, I'm using a bcm943602cs wifi+bt card with native support，but it seems like the firmware need upgrade to enable bluetooth in 10.12. I try the command the first time

./dfu-util 0x05AC 0x8290 /System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/IOBluetoothUSBDFU.kext/Contents/Resources/20703_8290.dfu

The file /System/Library/Extensions/IOBluetoothFamily.kext/Contents/PlugIns/IOBluetoothUSBDFU.kext/Contents/Resources/20703_8290.dfu contains a DFU suffix with the following properties:

[i] Transitioning from STATE_APP_IDLE into STATE_DFU_IDLE.

and the next try

I read the dfu_1.1.pdf, and i think the device did not change state of appDETACH to dfuIDLE after USB Reset. I have no idea how to solve this, please help!

i did not use PatchRAM Adapter Card WiFi-Bluetooth-Airport-Card I use this two things in my hackintosh and the WiFi works fine, buf Bluetooth may need a firmware update by dfu, now I am finding the way to do this.

What I mean is that the Bluetooth card you are using is most likely only supporting PatchRAM. Full DFU upgrade is usually only available on authentic Apple hardware. A PatchRAM device cannot by DFU upgraded but requires BrcmPatchRAM to handle the firmware.

Sorry for resurrecting an old thread. I'm having the same issue with the same card, legitimate Apple hardware running a legit copy of macOS on an rMBP. I am trying to update the card firmware which seems to have gotten corrupted in one of the latest software updates (10.13.6), after which bluetooth no longer works. Any ideas on how to put the card in DFU mode? Thanks in advance.

Hey, may be I can give you some information useful:

idevsoftware commented 6 years ago

Thank you for your feedback, the fact that the cards firmware gets uploaded on every boot seems reasonable to me. However I find it very suspicious that right after a software update it stopped working, the card now has a wrong product ID, bluetooth cannot be turned off on the preferences and no devices are detected.

PriMEtor commented 6 years ago

If possible, you can try a fresh install of 10.13.6 and see if problem still exists, be aware that this may erase your disk, it's recommended to backup your important data

idevsoftware commented 6 years ago

I did already. Tried reinstalling from scratch, going back all the way to El Capitan and even tried the Mojave beta. Bluetooth isn't even visible on versions < 10.13

PriMEtor commented 6 years ago

em... that looks really like a hardware problem

idevsoftware commented 6 years ago

right after a system software update? suspicious, to say the least
