Description

Sorry to bother you. I want to compile a slimmed version of the IntelBluetoothFirmware.kext that only contains the firmware for my card. I followed this guide: https://github.com/dreamwhite/ChonkyIntelBluetoothFirmware-Build

But in my case, the used firmware is not revealed by IORegistryExplorer:

Can you tell me which firmware it uses or is there a list of which firmware is used for which model?

Thank you

There is a known ~bug~ issue where the fw name disappears after waking up from sleep or from warm reboots, try cold booting directly to the system and see if it is there.

There is no way to retrieve the current fw version if it is not first recorded and uploaded by IntelBluetoothFirmware. Attempting to read the fw version from the device directly will return a wrong version.

Unfortunately, this also happens when booting normally.

Is there another way to figure out the firmware? A list or a terminal command or something in WIndows that I can look for? I also checked in Device Manager already. I couldn'tf find anything that points to the firmware used by this card.

You can also use ubuntu live to see the correct firmware name (using dmesg)

Okay, I can try that. What's the command I need to enter? Sorry, I am not a programmer.

@5T33Z0 dmesg or dmesg | grep ibt is enough.

I used ventoy to run a live version of Zorin from a USB flash drive and

dmesg | grep ibt

works!

Thank you very much!
