bluetooth headphone connection issue Big Sur

[amirsss]

Hello

I have a USB Bluetooth dongle (Asus BT400). I installed it on Big Sur without any kext, and it works. but when I want to connect my headphone, most of the time it says connect, but my device is still in pairing mode, but sometimes it will connect and sometimes show connect, and after a sec, it shows disconnect. I tried it with kext (BrcmBluetoothInjector+BrcmFirmwareData+BrcmPatchRAM3), but there was no difference, so I removed the kexts.

My device is

Monster Clarity HD On-Ear Sound Isolating Wireless Headphones​

and successfully connected through Windows.

Any help would be appreciated.

Remove those kexts and enable ExtendBTFeatureFlags and then check.

Attach your EFI to check.
