Bluetooth BCM2070A0 Not working

English Hardware
#1

Hello,

I am having BCM94352HMB Wifi + BCM2070A0 BT Combo Wifi Chipset. I got Wifi working properly but Bluetooth isn’t working and its GUI access is full of errors.

I have installed the required firmware **BCM20702A1-0a5c-21fb.hcd to /lib/firmware/brcm **and its loaded successfully.

Bluetooth is turned on in gnome-settings but no settings are available. Gnome applet says ‘Off’ for bluetooth but** Turn Off option **is also available.

The same firmware works perfectly with Ubuntu 19.04 and I am actually moving from Ubuntu to Opensuse.

Maybe try this one:
https://download.opensuse.org/repositories/home:/Sauerland/openSUSE_Leap_15.1/noarch/bcm20702a1-firmware-12011012-lp151.15.1.noarch.rpm
This is Version 12.01.1012 from Windows driver, I think you have installed Version 12.01.940 from winterheart

#3

As you said, I was using firmware from winterheart. I removed the one I installed and installed the package you shared. Same issue exists (I did restart the system with new firmware)
