[Bug 1065400] Re: Support for loading Broadcom bluetooth firmware

  Thread Previous • Date Previous • • Thread Next 
Hi,

I've got the same problem as Khunphil after a reinstall of Ubuntu(-Studio) on my Lenovo Ideapad G500. Firmware is in the brcm-folder with the correct name, but hci0 is not patched/loaded. 
btusb, bluetooth-touch, bcmwl-kernel-source is installed. Not installed is broadcom-sta-dkms. Tried to install it, but fails (see Bug #1504975). I don't know, if broadcom-sta-dkms is needed?? It's Ubuntu-Version 15.10.
Is there anything I missed? Is it the broadcom-sta-dkms?

Thanks!

  Support for loading Broadcom bluetooth firmware

Bug description:
  Broadcom bluetooth chips require a tool called patchram uploader [1]
  to load firmware. This applies to at least BCM20702 and BCM43142.
  Although some of the devices have an OTPROM that contains required
  firmware, but it is found that these devices would not have HFP/HSP
  support unless a upgraded firmware is loaded via patchram uploader.

  This tool requires hci device to do the firmware loading, but this may
  cause some race condition between patchram tool and bluetoothd or
  something that also works on hci interface.

  Also it needs some hooks to make firmware loads after bootup, s3,  s4,
  rfkill, and device hotplug events. Implement this loader in kernel
  module would make things more easier.
