BCM43142A0-0a5c-21d7.hcd
I can't seem to get the bluetooth working even after installing the firmware for my chipset. Bluetoothctl just shows that there is no default controller available.

Hello. You have Broadcom WiFi+Bluetooth combined device. Please try to apply these instructions: https://github.com/winterheart/broadcom-bt-firmware?tab=readme-ov-file#notes-about-combined-wifibluetooth-devices
@winterheart Thank you for responding I don't think I have the nvram file, is it named something different?

Can you please post full dmesg output? In any case, did you poweroff/poweron (not just reboot) notebook after bluetooth firmware install?
did you poweroff/poweron
Did that, nothing changed.
Here is the full dmesg output:
https://gist.github.com/9srp6/e34a261749008a6ae13efefacdafdb00
@winterheart
So I solved my problem.
I had to remove the .hcd file provided by this repo
I then followed the tutorial in the answer here.
I had to extract the required .hex file from the downloaded zip and convert it to the .hcd file with the required name.
Placing it in /lib/firmware/brcm/ and rebooting, I get no more errors.

bluetoothctl recognized my controller and I was able to scan for my devices.
I did however encounter some "br-connection-profile" errors when trying to connect my bt headset, which were solved by installing pulseaudio-bluetooth and starting the pulseaudio service.
Well, that strange.
Guess that device is pretty old and Broadcom didn't test well latest driver for compatibility issues. Can you please also test BCM43142A0-0a5c-21d7.hcd from https://github.com/winterheart/broadcom-bt-firmware/releases/tag/v12.0.1.1011_p1 version?
