Thread: Plugable usb-bt4le bluetooth 4.0 usb adapter, installation

    Default Plugable usb-bt4le bluetooth 4.0 usb adapter, installation

    opensuse 42.3

    the device https://plugable.com/products/usb-bt4le

    you may encounter problems with :
    - hfp/hsp , a2dp profile
    - activate/disactivate bluetooth with bluedevil plasmoid.

    to solve these problems you must supply the firmware of the device according system loads this firmware instead of a default one when pc starts .

    in a user console execute the following command to download the firmware file:
    Code:
    wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd
    in /lib/firmware/brcm
    Copy the firmware file to the /lib/firmware/brcm folder and rename the file to BCM20702A1-0a5c-21e8.hcd:
    Code:
    sudo mv fw-0a5c_21e8.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd
    why renaming ? because system with kernel 4.4.104 expects this name



    reboot pc

    check in boot.log there is no more message about failing to load firmware BCM20702A1-0a5c-21e8

    Yes and my dongle does not work with the older Version (940) from the github Repo, but with the newest (1012) extracted from the last Windows Driver.

    I have build an rpm with that Driver which works with my dongle......

    i sum up:

    - we get 2 different devices with same chipset
    - mine works with 940 version and not with 1012 version of the driver
    - yours works with 1012 version and not with 940 version of the driver

    i am a bit puzzled. what is solution ?
