TechAndrew Posted February 10, 2022 Share Posted February 10, 2022 Hello, Even though I no longer have a Broadcom card in my Monterey 12.2 Dell Latitude e7470 system (replaced with Intel 8260), I can still see a NULL Bluetooth controller that I do not want, as I suspect it's preventing my Bluetooth from working. What exactly is injecting this and how I prevent this from happening? I attached my OC folder (AirportItlwm.kext, IntelBluetoothFirmware.kext, and IntelBluetoothInjector.kext have been removed from the upload due to excessive size). Thanks!

Moderators Jake Lo Posted February 10, 2022 Moderators Share Posted February 10, 2022 I have an Intel AC9462 and the Bluetooth shows exactly as your screen shot. Bluetooth works perfectly fine. Make sure you have the latest IntelBluetoothFirmware, BlueToolFixup.kext, disable IntelBluetoothInjector for Monterey. Link to comment Share on other sites More sharing options...
TechAndrew Posted February 12, 2022 Author Share Posted February 12, 2022 I attached my OC folder... I have all of those installed, yet my Bluetooth isn't working. Nothing happens when I try to turn it on in System Preferences or from the top menu. It does show up under USB though: OC.zip Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted February 14, 2022 Administrators Share Posted February 14, 2022 does it work in windows or linux? I remember on the old dell DW BT modules they had to be activated / initialized in windows before they would ever work in OS X Link to comment Share on other sites More sharing options...
TechAndrew Posted February 15, 2022 Author Share Posted February 15, 2022 It works as expected in Windows, even after sleep. Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted February 15, 2022 Moderators Share Posted February 15, 2022 Try moving BlueToolFixup.kext above IntelBluetoothFirmware.kext in the config file Link to comment Share on other sites More sharing options...
TechAndrew Posted February 16, 2022 Author Share Posted February 16, 2022 Done. Still no luck, but I noticed this (Invalid Parameter error from BlueToolFixup.kext) during startup (not sure if it was there before): Link to comment Share on other sites More sharing options...
