Compatibility issue with Bluetooth 4.x devices
March 3, 2022 Update
https://github.com/OpenIntelWireless/IntelBluetoothFirmware/issues/51#issuecomment-995515730
@pwjun @influenist
After chatting with @zxystd and did some testing, it seems to be clear that macOS will ALWAYS disconnect devices that seem to be useless.
In order to maintain the connection with another non-apple or non-HID device, like Android phones, you have to turn on Bluetooth Internet tethering in the phone settings. With this enabled, you'll have a reliable connection and could send files successfully.
This kext, based on what I've understood, is literally a Firmware Uploader, it does the same job as other solutions like using VMs, directly rebooting from Windows, and so on. So, if you experience the same issue with other solutions, it has nothing to do with this kext. @zxystd said he will probably make some improvements based on the Lilu patch engine to enhance the user experience but that might happen only after he finishes his juicy Intel Wifi kext.
Hope this can help you guys.
Cheers for @zxystd!
@williambj1，Thank your help,on your help,I can connect my computer and smart phone、bluetooth musicbox，but bluetooth mouse can not work，hope help，thanks
Bluetooth 4.0 devices are problematic on Intel Cards right now, I can't connect to my keyboard as well. It's an issue mainly caused by incompatibility with Apple's drivers.
thank your reply John

I put the Bluetooth driver in clover, and it doesn't load at all when I put it in SLE. Intel 3160 network card
is this fixable or a limitation in the system that might not be able to be fixed?
My BT mouse works laggy in BT3.0 mode and not able to connect in BT4.0 mode. Subscribed this issue, hopefully there will be some solution of this situation.
蓝牙 4.0 设备现在在英特尔卡上有问题， 我也无法连接到键盘。这是一个主要由于与苹果司机不相容而引起的问题。
Will Bluetooth 4.0 be supported in the future？
Same with MX Anywhere 3 and Satechi M1. OpenCore 0.6.3 MacOS 10.15.7 IntelBluetoothFirmware 1.1.2
I'll continue this discussion https://github.com/OpenIntelWireless/IntelBluetoothFirmware/issues/217#issuecomment-727535960 here (because this other issue is closed). I'm a developper but I'm not familiar with this kind of developpment. However, having this issue too, I'd like to propose my help if anyone can lead this :-)! I'm a C#/Angular developper but I'm confortable with learning new technologies.
@BenDevelopment seems that it is HCI command related problems, you can use the HCI packet logger or capture tools to see what happend on paring/connecting.
ble debugger返回是这样，感觉是linux固件兼容问题。

Hi everyone and thanks for your analysis and contributions. Could it be however that we're uploading the wrong or rather, not-well-compatible firmware on a per-device/card basis? I mean, what if we try other firmwares for my Intel Bluetooth 9460/9560 Module (BTLE v5.1) device [8087:0aaa] and this BTLE has PCI ID is https://pci-ids.ucw.cz/read/PC/8087/0aaa
Could this not be a possible reason for macOS to not connect to some mice, game controllers etc. at all? Just curious. Thanks!
I only have this issue when using High Sierra, for whatever reason, macOS Catalina and Big Sur don't have any problems with playing Bluetooth audio. My WF-100XM3 earbuds disconnect when I play audio on my computer, but it Catalina and Big Sur, they work perfectly.
I wonder if there's some way to port the Bluetooth stack from Catalina to High Sierra, if it's even possible

用packetlogger看 这几句一直循环
@Basstorm, I watched the logs on my machine too, it looks like the problem with the Broadcom vendor specific commands which aren't understandable by the Intel controllers, may be only this one is a culprit 0xFCE9 (Broadcom LE Meta VSC). They should return kIOReturnSuccess looking at the logs on the actual Macs. May be there's a way to hack into this process and ignore those commands.
I also wonder if enabling Microsoft vendor extension would help. https://github.com/torvalds/linux/blob/master/drivers/bluetooth/btusb.c#L2923
Same issue with bluetooth 4.X on 2 different machines both with Big sur: First machine use an intel AX200, i can discover the bt4 devices but cannot finish the connection (xiaomi miiiw s500 mouse) Second machine use a intel 8260 (or a 8265 i don't remenber exactly), discovery of devices works, connection to an apple wireless keyboard 2009 works, cannot connect to a bt4 mouse.
Same issue for me.. Strix B450i with AX200 Paired my airpods pro immediately Can't connect any BT4.x device

I try connect bluetooth headset "mi air 2" it has bluetooth 5.0 and it connected successfully but microphone also not work.
The current solution to avoid the problem is to upgrade the Bluetooth card to v5 or better go with Broadcom cards. The best you can try with current card is to install itlwm (with Heliport) instead of Airportitlwm as it has better compatibily with the Bluetooth.
