Confirmation Asus USB-BT400 dongle not working under Sequoia

[adipierro]

@megabitzu could you please elaborate if it doesn't work with this PR or are you talking about release version?

[adipierro]

okay I've compiled BluetoolFixup with a compatibility fix from this PR, can confirm it works on 24A5331b

[adipierro]

but not after sleep :)
I will try to tinker with pmheart-btf15-20240616 branch

Hi, Same problem here on Sequoia... will be released a new version of the kext?

[FajleRabbi]

I'm also facing the same issue, is there any chances to release new version of the kext?

I'm curious where you got it from, it worked well for me, but it didn't apply any patches to /usr/sbin/bluetoothd, even thought it did work well for me.

I built from Lorys89's fork, but it doesn't work, and it's much smaller than your version.
By the way, your version of BlueToolFixup is the only one that works for me on the internet.
But there is a bug when the system shuts down, devices can not be released properly.
Where can I report it? Thanks a lot!

I have a flash drive with Bluetooth version 2, unfortunately the file above did not help, maybe in my case some other edits are needed?

This worked for me for ASUS BT-400. What is the difference?

With the below NVRAM Patch...

<key>bluetoothExternalDongleFailed</key>
<data>AA==</data>
<key>bluetoothInternalControllerInfo</key>
<data>AAAAAAAAAAAAAAAAAAA=</data>

I have a BT400 and the Bluetooth keeps searching and doesn't find any device. I've already tried using the BlueToolFixup.kext that they posted here, I also tried it with and without the NVRAM Patch. Does anyone know how to solve it? On Windows it works perfectly.

[vedantmgoyal9]

@zxystd can this be merged and hopefully, a new version of the kext can be released?

For me this (searching and doesn't find any device) happens when I use a USB that does not have a Broadcom chip.

How do I find out his chip??

If you have an ASUS BT-400 the chip should be a Broadcom chip.

@adipierro Does pmheart-btf15-20240616 work for you after sleep?

[adipierro]

@adipierro Does pmheart-btf15-20240616 work for you after sleep?

@PMheart, hi!

Not really, since some beta version it actually makes bluetoothd crash frequently, and not work at all.

Bluetooth works, however, after sleep with this simple PR, if I turn Bluetooth off before suspending machine. And a quick fix is resetting BluetoothExternalAdapterSomethingFailed in nvram, and killing bluetoothd afterwards.

It might just not be able to "see" the adapter while USB is re-initializing, and could be my machine specific.

I tried to patch out the NVRAM option write inbluetoothd as well myself by analyzing it with ida, but unfortunately don't have enough reverse engineering experience for this.

Will it be useful if I try to collect debug Bluetooth logs for you the moment it fails after sleep?

[PMheart]

Thanks for the heads up. Then for now I have no idea, apologies.

@adipierro Hi, thank you for testing. There's a recent fix on BlueToolFixup if you can help to test. 061486c You can download the kext in /~https://github.com/acidanthera/BrcmPatchRAM/actions/runs/11143115875

[adipierro]

@stevezhengshiqi thank you for letting me know about it 😊

I recently talked with PMheart about this patches in private, and I wanted to test them soon, but I still need to investigate bluetoothd crashes with it.

Although it mostly works with 15.1, there are still some issues after sleep. As soon as I find time for this I'd be happy to do it. Maybe even create new patches 👀

Thank you so very very much for this @adipierro ! After million reboots, kexts, maps.....whatever....this worked. I didn't even know how to do it, so if anyone stumbles upon this thread, here's the drill:

sudo NVRAM bluetoothExternalDongleFailed=%00
sudo pkill bluetoothd

Before that with 'NVRAM -p' you can actually check what's going on and if you have %01 up there, most probably you have a problem you can fix with this.

[debby97cheer]

一个快速的解决方法是在 nvram 中重置BluetoothExternalAdapterSomethingFailed，bluetoothd然后终止。

非常感谢@adipierro！经过无数次重启、kext、地图......不管怎样......这个终于成功了。我甚至不知道该怎么做，所以如果有人偶然发现这个帖子，下面是练习：

sudo NVRAM bluetoothExternalDongleFailed=%00 sudo pkill bluetoothd

在此之前，您可以使用“NVRAM -p”实际检查发生的情况，如果那里有%01，则很可能存在问题，您可以使用它来修复。

非常有用

So, the NVRAM set works for me, too, but this is not something that is viable (don’t have a usb keyboard and mouse, they are both bluetooth, so there’s no way to apply the setting). Any ideas?
