I had the same issue, and used the sfi file from the windows version. The main issue is that your card is revision 4 and the linux-firmware only has the firmware for revision 5.
You only need to decompress the file and copy the two files into /lib/firmware/intel and perform an hard reboot. And bluetooth should start working right away. Anyone knows whats the best way to get these files pushed to mainline linux-firmware package? ** Attachment added: "sfi and ddc file from windows driver" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1638862/+attachment/5022965/+files/ibt-11-4.tar.xz -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1638862 Title: [Dell Latitude E5460] bluetooth is not supported on 16.04.1.
