Broadcom BCM4352 Bluetooth lists MAC addresses and doesn't connect properly (WiFi fine)

Question

As you can see, the Bluetooth connection wizard does not work properly in (K)Ubuntu 18.04. I'm using an ASUS motherboard (Maximus VII Formula) with a WiFi PCI expansion using a Broadcom chip.

The specific output of lspci -nnk is as follows:

07:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter [14e4:43b1] (rev 03)
    Subsystem: ASUSTeK Computer Inc. BCM4352 802.11ac Wireless Network Adapter [1043:855c]
    Kernel driver in use: wl
    Kernel modules: bcma, wl

Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter (rev 03)

The WiFi adapter works fine. But it would seem that the Bluetooth adapter has broken functionality.

The only noticeable error is that it lists MAC addresses rather than the names of the devices. I will update soon with the same OS on my laptop to show the difference. It simply does not connect, and with MAC addresses, I am also unable to see which device it is - but I've gone through them all in connection attempts.

Can you elaborate "As you can see, the Bluetooth connection wizard does not work properly"? I don't see anything not working properly. What is the real problem? — Pilot6, May 10 '20 at 14:07

@SasukeUchiha What "drivers" are you asning about. There is no BT drivers that can be "updated". — Pilot6, May 10 '20 at 14:10
So mention that it doesn't connect in your question. It is not obvious. Did you click a device and press "Next"? — Pilot6, May 10 '20 at 14:11
@Pilot6 is right. You haven't given enough info on what you already tried. Also I think this will be better if we do this is a chat rather than in comments. — VidathD, May 10 '20 at 14:13
Give me some time to update what I've tried. And yes, I've exhaustively gone through the wizard trying to connect. — Jonathan, May 10 '20 at 14:14
So you need BCM20702A1-0b05-17cf.hcd. See https://askubuntu.com/questions/632336/bluetooth-broadcom-43142-isnt-working/ — Pilot6, May 10 '20 at 14:17
I think these may help too. https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM20702A1-0b05-17cf.hcd https://github.com/winterheart/broadcom-bt-firmware/blob/master/README.md — VidathD, May 10 '20 at 14:25
Second solution (noticed not written by you but all credit goes to you Pilot6 for helping me come to it) I think hopefully works - which does link to winterheart github page. — Jonathan, May 10 '20 at 14:30
Success! I still see some MAC addresses but I also see my JBL Clip 3 listed properly now and it connects successfully! Thank you guys. [ 3.983607] Bluetooth: hci0: BCM20702A1 (001.002.014) build 1469 [ 3.999610] Bluetooth: hci0: Broadcom Bluetooth Device — Jonathan, May 10 '20 at 14:31
I could also convert lots of firmwares, but uploding them to github is an illegal activity ;-) — Pilot6, May 10 '20 at 14:32
If you'd like to offer a solution, I will accept the solution mate, thank you so much — Jonathan, May 10 '20 at 14:32

You need firmware for this Bluetooth device. Here is how to get it and convert for Linux:

Download this Windows driver. http://drivers.softpedia.com/get/BLUETOOTH/Broadcom/ASUS-X99-DELUXE-Broadcom-Bluetooth-Driver-6515800-12009860.shtml#download
Extract Bluetooth_Win7-8-8-1_V6515800_12009860 from the archive.
Under Win8_Win81 -> Win64 directory you'll find BCM20702A1_001.002.014.1443.1469.hex file.
Convert it to BCM20702A1-0b05-17cf.hcd as mentioned here using hex2hcd:

Bluetooth Broadcom 43142 isn't working

Copy it to /lib/firmware/brcm

You can try to find an already converted file in some githubs.

For example this one has it.
