Is the Bluetooth for RTL8723DE made to work with related to this driver?
Hi, Thank you for the dirver provided for RTL8723DE wifi module. It works great so far. But, another issue with the new laptops like HP 15-BS576TX/BS000 range and others is, bluetooth driver missing. My assumption is, WiFi and bluetooth share the same hardware.
``
It is the same hardware but the bluetooth requires firmware and it might require changes to the btusb and btrtl modules
@jeremyb31 So, Will there any solution to get the bluetooth hardware to get to work? Any idea if, the bt firmware will be released by the manufacturer (Realtek).
If and when it is released by Realtek it should be logged at https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/log/rtl_bt
The strange thing is, is that I remember 1 post where the user said the bluetooth did work on the 8723DE chipset, https://forums.linuxmint.com/viewtopic.php?f=53&t=257254
What does lsusb reveal?
Well, lsusb list this:
Bus 001 Device 002: ID 0bda:b009 Realtek Semiconductor Corp.

You will have to wait for the firmware to get updated for bluetooth to function. The module might have some debugging level enabled since it is new
Here is a snapshot of kern.log full of talkative module : https://paste.ubuntu.com/26247041/ Full of messages like: Dec 24 22:31:13 kernel: RTW: traffic_status_watchdog(wlo1) acqiure wake_lock for 4500 ms(tx:99,rx_unicast:132)
echo "options 8723de rtw_power_mgnt=0 rtw_drv_log_level=0" | sudo tee /etc/modprobe.d/8723de.conf
That should change some things after a reboot or you could
sudo modprobe -r rtl8723de && sleep 20 && sudo modprobe rtl8723de
@jeremyb31 Well, that module options seems to have little effect. Messages like below is constantly logged on every session:

Uninstall from dkms and try using mine at https://github.com/jeremyb31/rtl8723de I just made some changes in Makefile that might help, or you could look at https://github.com/jeremyb31/rtl8723de/commit/f2a316bd79385878df5fb95d888de74301f3b56d and do the changes manually on the source code you have and then reinstall
Hi @smlinux @jeremyb31 , I tried extracting the windows driver provided for rtl8723de bluetooth hoping to get some clues on the firmware. Since I'm not technically experienced, I cannot find anything reasonable that is related as firmware. The only file that matches "fw" (firmware) name is a .dll file called "rtl8723d_mp_chip_bt40_fw_asic_rom_patch_new.dll". This, I got after extracting two data.cab files in the archive. I have listed the contents of the extracted data1, data2 cab files part of WIndows driver here: https://pastebin.ca/3959861 This is the latest RTL Windows driver provided by HP : http://ftp.hp.com/pub/softpaq/sp83501-84000/sp83944.exe
I was thinking, if it is possible to get a firmware dump of bluetooth from a Windows 10 laptop with RTL8723DE OR extract the bluetooth firmware from Windows drivers. Is there any chances, if this will work?
The firmware for bluetooth is listed as available now in kernel firmware git tree: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=6d5131107f2ba67a13f469ac770a55f101ba654d
I have git cloned and copied the contents of rtl_usb which includes rtl8723d firmware and config bin to /lib/firmware/rtl_bt and tried depmod -a. There is no effect and still the hardware is telling about 8723b bt firmware.

So, 8723B firmware is getting detected instead of 8723D.
Guys, try this, and make sure you checkout the extended branch to make: https://github.com/lwfinger/rtlwifi_new/tree/extended
The bluetooth still doesn't work for me, but according to https://github.com/lwfinger/rtlwifi_new/issues/353, this will finally be rectified by the yet unreleased 4.17 kernel (which I suspect will become stable some time in the next few weeks, as it's currently on its 5th weekly RC, and the previous two versions have taken 8 and 7 RCs, respectively).
Yes, Bluetooth is working good with 4.17-rc kernel. Kernel versions prior to 4.17 refers the rtl8723b firmware (which is wrong firmware) and ends up with the error "hci0: didn't find patch for chip id 2". I have listed the steps to get the bluetooth working here: https://superuser.com/a/1322067/850732 And WiFi steps here: https://h30434.www3.hp.com/t5/Notebook-Wireless-and-Networking/Realtek-8723DE-wifi-module-amp-Bluetooth-Linux-driver/m-p/6477307/highlight/true#M146067
@AvirahJ it works for me, i can use bluetooth or wifi now, but, when i am connected to wifi network, bluetooth connection is lost. only way that i have to view visibles bluetooth devices and connect them is if wifi is not connected
@AvirahJ I was also having the same problem. But I got help from here. I am using kernel 4.16.13 on Ubuntu so it works even without 4.17.x
You have to add this repository:
sudo add-apt-repository ppa:hanipouspilot/bluetooth sudo apt update
and then install this package:
sudo apt install btrtl-rtl8723de-dkms
It is available here: https://launchpad.net/~hanipouspilot/+archive/ubuntu/bluetooth
@viveikjha Thank you. ~~That got my rtl8723de bluetooth working on Ubuntu 18.04 using kernel 4.15.0.~~ Edit: Unfortunately, it turned out that the PPA got my bluetooth at least working, but the connection was very buggy and unstable.
@konbeto are you able to stream audio to bluetooth headphones? I am also on Ubuntu 18.04 with 4.15.0, and while I can detect and connect to my headset after following @viveikjha's instructions, it will not select them in the sound menu in settings.
Edit: Shifting to 4.16.13 with Ukuu resolved this issue.
@glodfinch Shifting to a newer Kernel seems indeed to be the better solution, due to the fact that the PPA approach results in a very unstable bluetooth connection on a closer examination.
I'd like to add that I probably jumped the gun with bluetooth working on later kernels, as has become clear by now. I'm currently running 4.18.9. Since 4.17 bluetooth has worked purely from the rtlwifi_new repo by lwfinger without additional setup. However the issue seems to be it has a poor signal quality. My bluetooth mouse works ok as long as it's within roughly a meter of my laptop, but bluetooth speakers of any kind will almost immediately start dropping audio and will usually disconnect completely after a little while - I'd guess it's related to how much data has to be transferred. As far as I know there's no solution to this at the moment.
Predictably just after I posted this I found this issue in lwfinger's repo: lwfinger/rtlwifi_new#382 And indeed switching off wifi makes bluetooth function perfectly. It does seem to have been brought up on the mailing lists: https://www.spinics.net/lists/linux-bluetooth/msg76878.html But no responses as far as I can make out.
Linux kernel 4.17.3-041703-generic. The same situation. Bluetooth began to work with [ 10.647823] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723d_config.bin [ 10.820288] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723d_fw.bin But link quality is poor (about 10%). So headset do not work with A2DP profile (sound is buggy because bandwidth is poor)
