    Unhappy Bluetooth BCM2070A0 Not working

    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.

    Code:

    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.

    Default AW: Bluetooth BCM2070A0 Not working

    Maybe try this one:
    https://download.opensuse.org/reposi...5.1.noarch.rpm
    This is Version 12.01.1012 from Windows driver, I think you have installed Version 12.01.940 from winterheart
    https://github.com/winterheart/broad...ee/master/brcm

    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)
