BrcmPatchRAM2 for 10.15 Catalina (Broadcom bluetooth firmware upload)

As BrcmPatchRAM3.kext depends on BrcmFirmwareData.kext, it is clear which one is first but with regard to the injector kext, I'm not sure but from my point of view it makes sense to put it in the third position.

In OC I have the kexts in this order : BrcmBluetoothInjector>BrcmFirmwareData>BrcmPatchRAM3/2

Thanks I originally had it in the 3rd spot and with this new update, put it first and both worked. Since this new update only has the injector instead of incorporating the firmware files as well, think it makes more sense to do it first since it's a service that brcmpatchram3 depends on. I wanted to confirm.

Ok, here is the latest build, version 2.3.0d1, in which I changed two things:

• Added an option to enforce handshake mode by setting bpr_preresetdelay=0 in order to test, if your device supports this mode of operation. Everybody is encouraged to try it. Please let me know, if it works on your device or not.
• Register for PM event notifications earlier in startup as it seems to speed up firmware upload a little bit.

Good luck testing!

Try it and if it works, fine, if it doesn't we'll know one device which is different!

thanks for hard work. i will try and remains log.
what is handshake? when sleeping, can we wake up to use bt mouse on system?

I have tried, The BrcmFirmwareRepo.kext is not work for my card BCM94352z but BrcmFirmwareData.kext

[speedyrazor]

Hi, I am using an HP Probook 440 G5 with a BCM20702A0. I have been previously using Mojave with no issue with Wifi or Bluetooth, using Rehabmans excellent guide 'HP ProBook/EliteBook/Zbook using Clover UEFI hotpatch'.

Upgraded to Catalina, Wifi is fine, but no detected Bluetooth anymore.

I came across your thread here, after reading, added both 'BrcmFirmwareRepo.kext' and 'BrcmPatchRAM2.kext' in Library/Extensions. Ran 'sudo kextcache -i /', rebooted, but still no Bluetooth device detected.

I have attached a screen grab of my System Info.

Any help would be greatly appreciated.

Thanks.

Same here, HP EliteBook 840 G4, update to Catalina 10.15 from the App Store went OK, Bluetooth is not working.

Wireless Card: DW1830

I tried to load BT firmware with headkaze BrcmPatchRam fork

What I already tried so far:

 

BrcmBluetoothInjector.kext

BrcmFirmwareData.kext

BrcmPatchRAM2.kext

load the 3 kexts in /EFI/Clover/kexts/Other -> leads to no bluetooth available

load the 3 kexts in /Library/Extensions then fix permissions and rebuild cache then restart -> BT shows and kinda scans devices.. but I cannot connect any device and something new I've noticed is that the physical BT indicator in my laptop flashes when it is scanning or trying to connect to something, never happened in previous macOS versions.
 

Handoff works...

 

BT firmware fails to load with kexts in /L/E I guess... Firmware Version: v5 c4096

 

 

Am I missing something else?

 

Here's my boot log bootlog.txt

 

Any help is appreciated, thanks.

I don't understand the first part of the 1st post. I copied the BrcmFirmwareData, BrcmPatchRAM2 and the BrcmBluetooth injector and paste them in EFI/CLOVER/kexts/Other.

Am I supossed to do something more?

Thanks for your job

what is handshake? when sleeping, can we wake up to use bt mouse on system?

What I call "handshake" is a mechanism which eliminates the need for boot parameter "bpr_preresetdelay" because it uses a message the BT controller sends to the host when it is ready to boot the uploaded firmware. In earlier versions this was decided by a fixed delay, "bpr_preresetdelay", which doesn't always work reliable causing BT to be unavailable after wakeup sometimes. I used to have this problem with my Dell Inspiron 13 5370.

Hi, running 

log show --predicate 'processID==0' --last 10m | grep BrcmPatch

Shows nothing and produces no files.

Then there is no driver installed, or the driver doesn't load for some reason. Also keep in mind that it only extracts log entries of the last 10 minutes.

Hmm, very odd, as I have in Library/Extensions:

BrcmPatchRAM2.kext

BrcmFirmwareRepo.kext

BrcmFirmwareData.kext

BrcmBluetoothInjector.kext

 

And my Bluetooth is activated:

 

Happy to provide any logs.

Where can we go from here?

BrcmFirmwareData.kext

Remove it because you must only have one of both data kexts installed. BrcmFirmwareData.kext or BrcmFirmwareRepo.kext but not both!

 

Try to load BrcmPatchRAM2.kext manually with

sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM2.kext

and check the output.

Ok, here is the latest build, version 2.3.0d1, in which I changed two things:

• Added an option to enforce handshake mode by setting bpr_preresetdelay=0 in order to test, if your device supports this mode of operation. Everybody is encouraged to try it. Please let me know, if it works on your device or not.
• Register for PM event notifications earlier in startup as it seems to speed up firmware upload a little bit.

Good luck testing!

Thanks for your hard work, my laptop get better power management with your patch, i'm using OpenCore 0.5.1 with BrcmBluetoothInjector.kext > BrcmFirmwareData.kext > BrcmPatchRAM3.kext

Remove it because you must only have one of both data kexts installed. BrcmFirmwareData.kext or BrcmFirmwareRepo.kext but not both!

 

Try to load BrcmPatchRAM2.kext manually with

sudo kextutil -v 5 /Library/Extensions/BrcmPatchRAM2.kext

and check the output.

OK, after removing BrcmFirmwareData.kext, rebuilt cache, rebooted, then running 'log show --predicate 'processID==0' --last 10m | grep BrcmPatch', I get:

I had BT at this point or so I thought, the icon was there and then I put it to scan for new devices (magic trackpad 2) and tried to connect to already paired ones with no results, no new devices were shown and it was unable to connect to any of the other ones.

 

Then I pressed option ⌥ + shift + click the Bluetooth icon in the status bar then Debug -> Reset the Bluetooth module. This made BT functional and it immediately scanned for the trackpad and paired with no problems, it now also connects to the other devices previously paired.

 

 

Is there any bluetooth log I can check to see what's going on?

 

BT information says my firmware is v5 c4518, is that ok? the logs show firmware upgrade was not needed

@SchillerX Firmware upgrades usually survive a warm boot so that there is no need to upgrade again. In order to get more logs, use the debug version of the kext and perform a cold boot.

 

@speedyrazor Remove headkaze's kexts completely and try mine (BrcmPatchRAM3.kext, version 2.3.0d1) from this thread. Install BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext and BrcmBluetoothInjector.kext to /L/E. Make sure that you don't mix headkaze's kexts with mine as this won't work.

FANTASTIC!! thats works, thank you so much. My Bluetooth is now working correctly again. Just to confirm I am using:

BrcmPatchRAM3.kext
BrcmFirmwareRepo.kext
BrcmBluetoothInjector.kext

In /L/E, all yours.

Thanks again

i am a bit confused.

I did put the files in the Clover --- others folder and when I use the command you posted above I get the following response:

But I used YOUR files... so.. shouldn't I get a response with anything like BrcmPatchRAM3?

 I haven't been lazy today, here is version 2.3.0d2. I improved some details of the driver:

• Changed SDK and deployment target to 10.11 in order to maintain compatibility with older versions of macOS. In case you are upgrading from an earlier version I posted here in the thread during the last days, please make sure to replace all kexts with the new ones (BrcmPatchRAM3.kext, BrcmFirmwareRepo.kext or BrcmFirmwareData.kext, BrcmBluetoothInjector.kext). Mixing kexts of different versions won't work.
• Improved error handling so that the driver better recovers from error conditions during firmware upgrade.

Good luck testing!

@barrrrt Most likely you forgot to recreate the kernel cache or you've still got the old ones in the 10.15 folder?
