Você precisa atualizar os firmwares de kernel e linux.

• Atualize seu kernel para a versão pelo menos 4.8
• Então você pode baixar um instantâneo do firmware do Linux, por exemplo link

sudo mv /lib/firmware /lib/firmware.old sudo tar xvfz linux-firmware-1dcf7691f623c24762976e2debe05248d627e814.tar.gz sudo mv linux-firmware-1dcf7691f623c24762976e2debe05248d627e814 /lib/firmware

Em seguida, baixe a fonte do pacote de bluez 5.46:

wget https://launchpad.net/ubuntu/+archive/primary/+files/bluez_5.46.orig.tar.xz wget https://launchpad.net/ubuntu/+archive/primary/+files/bluez_5.46-0ubuntu3.debian.tar.xz wget https://launchpad.net/ubuntu/+archive/primary/+files/bluez_5.46-0ubuntu3.dsc sudo dpkg-source -x bluez_5.46-0ubuntu3.dsc

Instale dependências de compilação.

sudo apt build-dep bluez sudo apt install devscripts cd bluez-5.46

Construa os pacotes.

sudo debuild -b -uc -us cd .. sudo dpkg -i bluetooth_5.46-0ubuntu3_all.deb \ bluez_5.46-0ubuntu3_amd64.deb \ bluez-cups_5.46-0ubuntu3_amd64.deb \ bluez-hcidump_5.46-0ubuntu3_amd64.deb \ bluez-obexd_5.46-0ubuntu3_amd64.deb \ bluez-tests_5.46-0ubuntu3_amd64.deb \ libbluetooth3_5.46-0ubuntu3_amd64.deb \ libbluetooth3-dbg_5.46-0ubuntu3_amd64.deb \ libbluetooth-dev_5.46-0ubuntu3_amd64.deb sudo reboot

Você deve então ser bom para ir.
