How to activate bluetooth device for RTL8723DE?
Support for this bluetooth device had been just added to the 4.17rc kernel.
The code can be easily backported to kernels 4.4 - 4.15. I made a PPA with DKMS packages for bionic
and xenial
with the updated btrtl
module.
It can be installed by
sudo add-apt-repository ppa:hanipouspilot/bluetooth
sudo apt update
sudo apt install btrtl-rtl8723de-dkms
You may also need firmware for this device if it is not there. Look into your /lib/firmware/rtl_bt
directory. If there are no rtl8723d_config.bin
and rtl8723d_fw.bin
files, clone the latest linux-firmware
by
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
and get the files from there. It is not that hard. Sorry that I forgot to add the firmware to the package.
The DKMS should survive kernel upgrades.
Important!: Ubuntu 18.04 has the 5.3
HWE kernel now. REMOVE this package if you are on 5.3+ kernels. Otherwise BT won't work.
