Broadcom Bluetooth not working in x86 volumio

hardware: Broadcom BCM943228HMB 802.11abgn 2x2 wi-fi adapter
Volumio x86 version RELEASE DATE: 18-03-2020

I installed pakage firmware-b43-installer , and wifi is working good.

volumio@volumio:~$ dmesg | grep failed

Then I follow the instruciton from github.com/winterheart/broadcom-bt-firmware.git
Notes about combined WiFi+Bluetooth devices
Some Bluetooth controller (for example, BCM4354 and BCM4356) are integrated to WiFi chipset (this can be BCM43XX 802.11ac Wireless Network Adapter or just simple generic Broadcom PCIE Wireless). These devices requires two kinds of firmware - first for WiFi, and second for Bluetooth. Without WiFi firmware Bluetooth will not initialize and will not work properly. Firmware for WiFi already included to kernel, but you may need to do additional work to place correct NVRAM.

Here example how it can looks (note about brcm/brcmfmac4356-pcie.txt loading - this is your customized NVRAM):

usbcore: registered new interface driver brcmfmac
brcmfmac 0000:02:00.0: firmware: direct-loading firmware brcm/brcmfmac4356-pcie.bin
brcmfmac 0000:02:00.0: firmware: direct-loading firmware brcm/brcmfmac4356-pcie.txt
Bluetooth: hci0: BCM: chip id 101
Bluetooth: hci0: N360-11
Bluetooth: hci0: BCM4354A2 (001.003.015) build 0000
bluetooth hci0: firmware: direct-loading firmware brcm/BCM4354A2-13d3-3485.hcd

I read above and download the file “BCM20702A1-0a5c-21f1.hcd Version 12.0.1.940” , rename and copy to directry /lib/firmware/brcm/brcm/BCM20702A0-0a5c-21f1.hcd
(sudo mv BCM20702A1-0a5c-21f1.hcd /lib/firmware/brcm/brcm/BCM20702A0-0a5c-21f1.hcd)

then reboot. however bluetooth still not working.
Anyone know how to get this Broadcom wifi-bluetooth card working?

This is not supported with the currently released X86 version.

But could you try the latest image from https://forum.volumio.org/volumio-x86-debian-buster-debugging-party-beta-t13957.html?
Let me know how it went, perhaps we could add from that version.

Tried that img , but Broadcom Bluetooth is not working in my volumio pc. Broadcom wireless driver is not opensource. I dont know where to download its Linux firmware, mostly driver I found is windows-based.
