I built a test module. You can install it by running terminal commands: wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth/+files/btusb-lp1542944-dkms_0.1_all.deb sudo dpkg -i btusb-lp1542944-dkms_0.1_all.deb
Then power off the laptop and power it on. If that does not work, post output of dmesg | grep ath3k And that can be fixed by installing new firmware from xenial by wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.155_all.deb sudo dpkg -i linux-firmware_1.155_all.deb ** Changed in: linux-lts-wily (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1542944 Title: QCA9565 / AR9565 bluetooth not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-wily/+bug/1542944/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
