I've updated BrcmBluetoothInjector to include all the missing device-id's from BrcmPatchRAM2.

- Added the following device-id's (vid:pid) to BrcmBluetoothInjector:

0489:e046, 0489:e04f, 0489:e052, 0489:e055, 0489:e059, 0489:e087, 0489:e096, 0489:e0a1, 04ca:2004, 04ca:2005, 04ca:2006, 04ca:2009, 04ca:200e, 04ca:2012, 04ca:2016, 04f2:b4a1, 0930:021e, 0930:021f, 0930:0225, 0930:0226, 0930:0229, 0a5c:2168, 0a5c:2169, 0a5c:216a, 0a5c:216c, 0a5c:216d, 0a5c:21d7, 0a5c:21e3, 0a5c:21f1, 0a5c:21f3, 0a5c:21f4, 0a5c:640b, 0a5c:6410, 0a5c:6412, 0a5c:6413, 0a5c:6414, 0a5c:6417, 0a5c:6418, 0a5c:7460, 0b05:17b5, 0bb4:0306, 105b:e065, 105b:e066, 13d3:3384, 13d3:3388, 13d3:3389, 13d3:3392, 13d3:3427, 13d3:3482, 13d3:3484, 13d3:3504, 13d3:3508, 145f:01a3, 413c:8197

- Already supported device-id's (vid:pid) in BrcmBluetoothInjector:

0489:e032, 0489:e042, 0489:e079, 0489:e07a, 04ca:2003, 04ca:200a, 04ca:200b, 04ca:200c, 04ca:200f, 050d:065a, 0930:0221, 0930:0223, 0a5c:216b, 0a5c:216e, 0a5c:216f, 0a5c:21de, 0a5c:21e1, 0a5c:21e6, 0a5c:21e8, 0a5c:21ec, 0a5c:21fb, 0a5c:21fd, 0b05:17cb, 0b05:17cf, 0b05:180a, 13d3:3404, 13d3:3411, 13d3:3413, 13d3:3418, 13d3:3435, 13d3:3456, 413c:8143

I've also created a Github fork of the project @ OS-X-BrcmPatchRAM

Hi Headkaze, I've just finished installing the new kexts and they work beautifully (For some strange reason I couldn't get the cp commands to work properly - error message about no such file or folder - so instead I used Kext Utility, rebooted and success). Many thanks for putting these together.

BrcmBluetoothInjector has been updated to include 0a5c:6410

headkaze, can you please add 21ff_0a5c as well?

Attached are updated BrcmPatchRAM2-Info.plist and BrcmBluetoothInjector-Info.plist files (copy them over BrcmPatchRAM2.kext/Contents/Info.plist and BrcmBluetoothInjector.kext/Contents/Info.plist respectively). What I've done is add the firmware from 0a5c:21fd (BCM20702A1_001.002.014.1443.1463_v5559) for your 0a5c:21ff entry. Can you give it a try and let me know if it works. If it does I'll add it to the official release.

Hello, I just tried your fork on BCM94352Z with 0489:e07a BCM20702A0 but it didn't work.

With Rehabman's fork, I use BrcmPatchRAM2 and merged BrcmFirmwareRepo with Injector plist. They are injected via OC, worked in Mojave but not in Catalina.

After I replaced them with your build, they won't work in both macOS version.

The BrcmPatchRAM2 is not loaded in Catalina, while both BrcmFirmwareData and Injector could load successfully and appeared in IOReg. I have also installed it with BrcmFirmwareRepo to LE but also no success.

The kext is loaded in Mojave, but Bluetooth is not functional, shown as "Bluetooth: Not available" in menu bar.

I have collected following log:

Thank you.

Update: I forgot to attribute the IOKitPersonalities to specify the ID, so the driver failed to load. After I merged the Injector to Repo kext, everything works again on Mojave. So the logs ahead could be ignored. However, the BrcmPatchRAM2 kext are still not loaded in Catalina, while that firmwarestore (with injector) one works and lead to 4096 firmware. I'm still investigating the issue.

No issues here using all three BRCM kexts in Catalina as per OP

Going by your log it looks like you had multiple installs of the kexts. Make sure you only have them in one place.

You shouldn't need to add 0489:e07a to IOKitPersonalities as it's already supported. What plist did you need to add it to?

4096 is indication of the firmware failing to be uploaded not success.

1820A Starting with mojave Bluetooth upload firmware should be a problem. To use the 5799 firmware only with a virtual machine. Please forgive me, English is not very good.

Your log shows the firmware was uploaded successfully. So is BrcmBluetoothInjector failing to load Apple's native driver? Are you sure you have the latest version from Github since 0a5c:6412 was only added in a recent update.

When I try to load BrcmPatchRAM2 in Catalina dp2 with Opencore 0.0.3, I get "Invalid Parameter" and the kext won't load.. I have a DW1560 bluetooth 0a5c_216f. Should this be working or is a fix in the process? Or, could it be that i'm doing something wrong?

Can you post the actual log where it shows "Invalid Parameter"?

This is the opencore 0.0.3 log. I have the latest release of brcmpatchram2 from your github.

opencore.log

It looks like an issue with OC injecting the kext not with the kext itself. Probably best to try one of the OC forums here.

按照你的日志，看起来你有多个安装的kexts。确保你只在一个地方。

您不需要将0489：e07a添加到IOKitPersonalities，因为它已经被支持。您需要将它添加到什么plist？

4096表示固件无法上传但未成功。

您的日志显示固件已成功上载。那么BrcmBluetoothInjector是否无法加载Apple的本机驱动程序？你确定你拥有Github的最新版本，因为0a5c：6412只是在最近的更新中添加的。

你能发布显示“无效参数”的实际日志吗？

Confirm the latest github used. It is available to restart from win to mac Bluetooth... This phenomenon should start from 10.14. DW1820A Bluetooth has been bothering me.

Your log shows:

[0a5c:6412]: Firmware upgrade completed successfully.

So upload is successful but it seems BrcmBluetoothInjector fails to load the native driver (BroadcomBluetoothHostControllerUSBTransport) afterwards. Where are you installing the kexts?

hi I'm running Catalina 19A501i on my new Dell XPS 7950. Everything works smooth except the communication with my Apple Watch. Handoff (and all other related stuff like clipboard, taking pictures..) with iPhone works great and fast but not at all with Apple Watch (handoff, unlock). Got the DW 1830, running your latest kexts, FW upload is successful. (thanks at this point for your great work!).

Could it be firmware or kext related? Is someone aware of this kind of issues with DW1830?

Hi there @headkaze I have mixed results with your method, at the end, in order to have the DW1820A work (0xa5c_6412) I have to boot into W10 or Linux, then it works. If I turn off the computer and cut the power (like a power cycle) when turns on again my Bluetooth doesn't work anymore.. Here is a screenshot of log (.kext are located at /CLOVER/Kext/Other y previously had them inside /Library/Extensions/)

It may just be a case of lag. I have a Dell XPS 8500 with BCM94352. Handoff took about 2 days (no action taken by me other than installing kexts) before handoff started working with my iPAD and 3 days before it worked with my iPhone.

You've posted a log of an unsuccessful firmware upload due to it already being uploaded (in your case most likely by Windows). You need to post the log showing the failed upload.

Hi Headkaze, I've just finished installing the new kexts and they work beautifully (For some strange reason I couldn't get the cp commands to work properly - error message about no such file or folder - so instead I used Kext Utility, rebooted and success). Many thanks for putting these together.

No longer working after update to 10.15 Beta (19A512f). System reports Firmware version as v14 c4096 using BCM94352HCM. When I have more time, I'll investigate further.

Here is the log without firmware update from Windows.

Here is the IOReg screen

Funny because I try to manually edit BrcmPatchRAM2.plist in order to load latest Firmware in your repo (v6820) but it just doesn't work shows fw V4096.. I'll try your firmware with old set of .kext (RehabMan's) to see if any difference..

The error code 0xe00002ed refers to an IO error communicating with the Bluetooth device. Have you ever had Bluetooth working on your Hackintosh?

You shouldn't need to edit any plist for your device (0a5c:6412) as it's already supported. It also has the latest firmware (12.0.1.1010).

Indeed. I've had several cards installed in this same build and other similar builds (DW1560), right now is sort of working with your .kexts but it has to be right next to the antena, otherwise it won't work at all, as soon as i move the device away, there is choppy behaviour or connection loss...

I have looked over at the Dell website and the latest I could find is the 12.0.1.1105, which is the one I have loaded, but still it doesn't work as it should.. Perhaps moving to Catalina would make the difference?? I don't see why this kext wouldn't work under Mojave 10.14.6... Perhaps you've modified the BrcmBluetootInjector.kext in a way that only runs in Catalina?? I've looked everywhere and could not find the kext, I've even posted an issue at @RehabMan repo but have received no reply.. Unfortunately for me moving to Catalina is not an option yet (apps and whatnot) but I need this bluetooth functionality..

Here the .kext with the latest firmware, which by chance is v4689 as it is loaded by windows correctly.
