DW1820A Bluetooth does not work properly in some circumstances #125

ivmm · 2019-11-16T16:18:16Z

Describe the bug
The NUC8i7HVK has a network card for the 1820A (CN-08PKF4). EFI uses the 2.4.0 version and opens the 1820A support option. BIOS already disable ASPM.

Wifi can be driven directly, but there is a problem with Bluetooth, you can display Bluetooth, but you can't connect any devices.

Expected behavior
Successfully running Bluetooth.

I'm not sure if extension acfs is related to bluetooth.

May you can check this page (mine is working fine):

ivmm · 2019-11-17T05:45:27Z

There is a Bluetooth information page, but you cannot connect to a Bluetooth device, you can view the device, but you cannot connect.

PCI information page is empty

lmshsqlc · 2019-11-17T06:07:06Z

I used to have this problem before I switched over to apples airport card From DW1830A. No matter I was on cold boot or warm boot, sometimes I will see devices in the Bluetooth panel but neither of them I can connect to.
for example I have a Magic Trackpad. Normally the system will connect every time does it start up and I connected pop-up will show on screen. But sometimes even if I manually connect from Bluetooth panel it won’t connect but it tries to.
There’s a thread from daliansky which I think is relevant to this problem. He implemented a delay for the Bluetooth firmware patch on wake.
https://blog.daliansky.net/DW1820A_BCM94350ZAE-driver-inserts-the-correct-posture.html
And by the way I think this might need to file an issue on BrcmPatch repo.

dickding · 2019-11-17T08:17:58Z

Yes, I have the same problem with my dw-1820a(CN-08PKF4)...sometimes it works, but sometimes, you can see the device but can not connect.

osx-10.15.1, hacmini 2.4

I have tried as you told, and it works!
I had the some problem as yours. I add the boot args to implement a delay for the Bluetooth firmware patch, which is just follow what the daliansky said in his blog.
I add "bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300" to the boot args. After that, I can use the DW1820A's bluetooth to connect my devices. It seems that the problem solved.
My device information is:
NUC version: NUC8i7HVK
macOS version: 10.15.1
HaC-Mini version: 2.4
DW1820A version: CN-08PKF4

goodbest · 2019-11-17T10:53:15Z

@catalina86
Actually, these settings bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300 is also listed in acidanthera/BrcmPatchRAM readme.
So I think it's quite reasonable.

jackson325 · 2019-11-17T11:30:52Z

@goodbest
Yep, I think this is a way to solve the problem. I've worked on it for a day. The result is fantastic for me. I think you @ivmm can try this solution.

ivmm · 2019-11-17T13:51:51Z

I added the relevant statement, but it didn't work. Bluetooth is still unable to connect to the device.

jackson325 · 2019-11-17T14:30:24Z

@ivmm
Have you forgotten all the bluetooth devices after reboot into the OS? Forget the bluetooth devices and connect them again. I had the similar problem and solved in this way.

ivmm · 2019-11-17T14:42:48Z

I grew up removing all Bluetooth devices and restarting the system after turning off Bluetooth. I still can't connect to the device.

jackson325 · 2019-11-17T14:54:06Z

@ivmm Maybe there are some differences between different cards. You can follow the README of the acidanthera/BrcmPatchRAM repo. It said:

Note: Some with the typical "wake from sleep" problems are reporting success with: bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300. Or slightly longer delays: bpr_probedelay=200 bpr_initialdelay=400 bpr_postresetdelay=400.

You can change the delay time as the instruction said and try again. Wish you good luck.

ivmm · 2019-11-18T15:08:53Z

@dickding You are right, you can connect to Wi-Fi normally using native thunderbolt, thank you!

goodbest · 2019-11-19T12:37:38Z

Maybe there is some bug in BrcmPatch v2.5 itself? We'd better wait and see.

Some none-nuc D1820A users are reporting [mixed results].(https://www.insanelymac.com/forum/topic/339175-brcmpatchram2-for-1015-catalina-broadcom-bluetooth-firmware-upload/?page=11)

For me, I have some issue with the patch v2.5 on a dell hackintosh laptop under 10.14.6, but it works flawlessly with RehabMan's original patch (which is not working for 10.15)

wittyofficer · 2019-11-21T18:20:50Z

@ivmm I also had the same issue but adding brcmfx-driver=2 argument to boot-args seems to solve it.

brcmfx-driver=2 enables the AirPortBrcmNIC kext in AirportBrcmFixup. You can refer to it in acidanthera/AirportBrcmFixup readme.

chrisallen · 2019-12-09T22:08:46Z

I am also seeing the same issue with my DW1820A (part# CN-096JNT) where devices show up but will not connect.

My issue appears to be the same as what this user mentions (https://www.tonymacx86.com/threads/the-solution-dell-dw1820a-broadcom-bcm94350zae-macos-15.288026/post-2042843) but I don't have Linux or Windows installed to dual boot into)

My boot-args are alcid=11 shikigva=32 shiki-id=Mac -disablegfxfirmware brcmfx-country=NZ bpr_probedelay=100 bpr_initialdelay=300 bpr_postresetdelay=300 (I have even tried brcmfx-driver=2 which made no difference)

Here is the log from last boot.

Does anyone know how to fix the issue of not being able to connect to detected devices?

It happens sometimes. Usually what I’m doing is perform a cold restart. Maybe you can check this out as well.

I've reported this over at InsanelyMac (https://www.insanelymac.com/forum/topic/339175-brcmpatchram2-for-1015-catalina-broadcom-bluetooth-firmware-upload/?do=findComment&comment=2700139)

goodbest · 2019-12-13T14:20:50Z

@chrisallen The most reliable temp fix for the issue is to boot into windows first (which has the proper bluetooth driver installed), and then you can have your bluetooth everywhere in macos.

The reason may be related to firmware upload in those kexts (although hackintools says fw loaded)

iiicwx · 2019-12-21T09:33:29Z

I had the same issue before, but a cache rebuild fixed it.

zhxiyao · 2019-12-21T16:29:20Z

I had the same issue before, but a cache rebuild fixed it.

May you tell more specifically about how to rebuild the cache?

iiicwx · 2019-12-21T16:49:14Z

it was to rebuild the system and kext caches, I used KCPM Utility Pro to do that.

crhendo · 2020-01-17T00:23:02Z

While WiFi has been working perfectly, Bluetooth is sporadic and very frustrating. I have tried all the suggestions (that I could apply) both here and on other threads but I always end up in the same predicament ie I can see the keyboard and mouse, I can click connect on both of them but they simply will not connect. I remove power for 24 hours and sometimes I can reconnect but eventually they simply disconnect again.

My solution was to deselect the DW1820A in HaC Mini Installer, reboot and in insert my old original IOGear Bluetooth USB dongle. All my Bluetooth devices now behave as they should and surprisingly the DW1820A WiFi works OK without being selected in the installer.

crhendo · 2020-01-17T01:41:46Z

Warning! While Handoff and other features are working as they should, unlocking using my Apple Watch does not work and further investigation tells me that Bluetooth 4.2 is required for this feature. (IOGear is only 4.0)

You won’t get a flawless unlocking experience until you use an Apple airport card. Apple Airport card is the only that automatically keeps connections to accessories. Using a third party Bluetooth will give you unlock only once you’ve got it setup.

I met same issue, and I observed one interesting thing.

Every time bluetooth works if the firmware upgrade is not needed.

shutdown and boot fix the issue(tested several times)

BTW, is there a way to bypass firmware loading?

lmshsqlc · 2020-01-29T16:10:52Z

BTW, is there a way to bypass firmware loading?

Firmware must be loaded for 3rd party Bluetooth card, as windows driver also loads a firmware. Sometimes a reboot from windows can make bluetooth work because the firmware has already updated by windows driver. Checkout Brcmpatch manual for further information.
An Apple airport card can guarantee your experience as they always works out of the box.

I have only Hackintosh in the box, no windows or other system at all, single SSD with only MacOS v10.15.2 on it. No USB stick plugged in.

I guess the default firmware in the chipset is the same as what the patch are trying to load.

lmshsqlc · 2020-01-29T16:36:16Z

I guess the default firmware in the chipset is the same as what the patch are trying to load.

The firmware is not in the chipset but in the Wi-Fi card itself. it has a Bluetooth firmware that needs to be updated every time it cold boots or it won’t work. Maybe it’s a bug related to brcmpatch. but when I was using a 3rd party card, a reboot might fix the problem.

JeffreyVIP · 2020-01-30T10:11:43Z

@osy86 Just tried release version 2.6, cache rebuild can't make bluetooth connection working, so I can do nothing but re-install v2.5 to restore bluetooth back.

I have the same problem with you when I install the DW1820A Card into the slot after my installation,that's why the problem accourd, tried several ways to solve that as using all the mothod above.
Till I realized I may try rest NVRAM as did on a commin Mac, So I reset NVRAM and it worked,both my MagicKeyborad2 and bt headphones .T_T
