HP 231d (ProBook BT built-in firmware).

Non-PatchRAM devices (BrcmPatchRAM used to speed up recovery after sleep): The following devices are supported at the moment:Дevices marked with * are tested successfully Supported DevicesД«rcmPatchRAM supports any Broadcom USB bluetooth device based on the BCM20702 chipset (possibly other chipsets are supported also, but this has not been tested). Requires Lilu 1.5.4+Дo not use it with BrcmBluetoothInjector for macOS 12 or newer. Required for macOS 12 or newer, as in macOS 12 Apple has changed parts of the Bluetooth stack from kernel-space to user-space as detailed in here and here. If yours is not present, edit the ist as needed.

You might also want to try this kext if you wish to see if your device will work without a firmware uploader.Дo not use BrcmPatchRAM or BrcmPatchRAM2 with this kext.

The BrcmBluetoothInjector.kext is a codeless kernel extension which injects the BT hardware data using a plist it does not contain a firmware uploader. IOCatalogue::addDrivers, IOCatalogue::removeDrivers and IOCatalogue::startMatchingД¬onsequently to have the native BT driver load for the device (BroadcomBluetoothHostControllerUSBTransport) we inject using a plist with a slightly lower IOProbeScore than BrcmPatchRAM3 so it doesn't probe before the firmware upload. This is due to the removal of the following IOCatalogue methods: Using BrcmPatchRAM3.kext also requires BrcmBluetoothInjector.kext as changes in macOS Catalina (10.15) requires the use of a separate injector kext. Use BrcmBluetoothInjectorLegacy.kext for older systems.

BrcmNonPatchRAM2.kext: for 10.11 or later.

BrcmNonPatchRAM.kext: for 10.10 or earlier.

#BROADCOM BCM20702 BLUETOOTH 4.0 USB DEVICE DRIVER ERROR INSTALL#

Although these kexts do not install any firmware (these devices have firmware built-in), they still depend on BrcmPatchRAM/BrcmPatchRAM2.kext. In case you forget to install BrcmBluetoothInjector.kext, Bluetooth will appear to be available but it won't work at all.ДЄlso, if you have a non-PatchRAM device (or you're not sure), install one of BrcmNonPatchRAM.kext or BrcmNonPatchRAM2.kext, depending on macOS version, never both. Starting with macOS 10.15, this is the only supported configuration because due to framework changes BrcmPatchRAM.kext and BrcmPatchRAM2.kext are incompatible with macOS 10.15. Keep in mind that BrcmPatchRAM3.kext also requires BrcmBluetoothInjector.kext to be installed. If you're using the injector through the bootloader, the IOProviderClass in the ist for BrcmFirmwareRepo.kext must be changed from 'disabled_IOResources' to 'IOResources'. Optionally, you may remove all the firmwares from BrcmFirmwareRepo.kext/Contents/Resources. This works from either /S/L/E or through bootloader injection.

This kext is slightly more memory efficient than BrcmFirmwareData.kext, but cannot be injected by a bootloader.ДЄdvanced users: For custom firmware injectors, install the injector plus BrcmFirmwareRepo.kext. This is the preferred configuration.Д«rcmFirmwareRepo.kext: Install to /System/Library/Extensions (/Library/Extensions on 10.11 and later). Install one of BrcmPatchRAM.kext or BrcmPatchRAM2.kext or BrcmPatchRAM3.kext depending on macOS version, never both.ДЄlso, install one firmware kext BrcmFirmwareData.kext or BrcmFirmwareRepo.kext, depending on installation location, never both.Д«rcmFirmwareData.kext: Most appropriate for bootloader injection.

Note if you have an Apple MacBook/iMac/Mac Pro etc, follow the Mac instructions Note that the original Apple Broadcom bluetooth devices are not RAMUSB devices, and thus do not have the same firmware mechanism.

#BROADCOM BCM20702 BLUETOOTH 4.0 USB DEVICE DRIVER ERROR DRIVERS#

The firmware applied is extracted from the Windows drivers and the functionality should be equal to Windows.

#BROADCOM BCM20702 BLUETOOTH 4.0 USB DEVICE DRIVER ERROR UPDATE#

It will apply the firmware update to your Broadcom Bluetooth device on every startup / wakeup, identical to the Windows drivers. BrcmPatchRAM kext is a macOS driver which applies PatchRAM updates for Broadcom RAMUSB based devices. The Broadcom Windows driver will upload firmware into the Broadcom Bluetooth device on every startup, however for macOS this functionality is not supported out of the box. RAMUSB allows the firmware for the device to be updated on-the-fly, however any updates previously applied are lost when shutting down the machine. Most Broadcom USB Bluetooth devices make use of a system called RAMUSB.
