You need to upgrade kernel and linux firmwares.

Upgrade your kernel to version at least 4.8
Then you can download a snapshot of linux firmware, for example https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-1dcf7691f623c24762976e2debe05248d627e814.tar.gz

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

Then download the package source of 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

Install build dependencies.

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

Build the packages.

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

You should then be good to go.
