VergilGao Posted May 10, 2022 Share Posted May 10, 2022 (edited) I bought a bluetooth usb device using rtl8761bu chip, it can drive in unraid6.9.2 version, but when I run `bluetoothctl` scan on, it can't scan any device. When looking for information, I found the kernel patch and the temporary solution. patch: https://patchwork.kernel.org/project/bluetooth/patch/[email protected]/ temp: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1955916/comments/21 I followed the temporary solution and completed the following repair script #!/bin/sh set -e ko_path=/lib/modules/"$(uname -r)"/kernel/drivers/bluetooth sudo cp "${ko_path}"/btusb.ko.xz "${ko_path}"/btusb.ko.xz.bak xz -dkf "${ko_path}"/btusb.ko.xz xxd "${ko_path}"/btusb.ko | sed 's/ca04 0540/5025 6187/g' |xxd -r > "${ko_path}"/btusb.ko.mod mv "${ko_path}"/btusb.ko.mod "${ko_path}"/btusb.ko xz -f "${ko_path}"/btusb.ko chmod 644 /lib/modules/"$(uname -r)"/kernel/drivers/bluetooth/btusb.ko.xz sudo cp /boot/config/custom/firmware/rtl8761b* /lib/firmware/rtl_bt chmod 644 /lib/firmware/rtl_bt/rtl8761b* modprobe -r btusb && modprobe btusb the usb device worked successfully. Please let me know if this is fixed in 6.10. Edited May 10, 2022 by VergilGao Quote Link to comment
VergilGao Posted May 21, 2022 Author Share Posted May 21, 2022 Glad to see that this problem has been fixed in 6.10.0, but because unraid lacks the necessary driver, users using rtl8761bu need to release the driver to the corresponding location by themselves Note that the corresponding files are named as described in this post https://linuxreviews.org/Realtek_RTL8761B#comment-2320 1 Quote Link to comment
abuhamsa Posted May 30, 2022 Share Posted May 30, 2022 Would like to see rtl8761bu included or if anyone can make the driver as a plugin 1 Quote Link to comment
runraid Posted August 6, 2022 Share Posted August 6, 2022 Also +1'ing this. Home assistant now supports Bluetooth. Those of us running Home Assistant via docker will hit this issue. I'm not sure how to get the above work arounds working so as for now, I can't use the USB bluetooth receiver I bought to control bluetooth devices with Home Assistant. Quote Link to comment
runraid Posted August 6, 2022 Share Posted August 6, 2022 I was able to get it working by following this thread I installed "nerd tools" via community apps, went to the plugins tab in unraid and clicked the "nerd tools" icon... and then i searched for "bluez" and turned it on. Next I putting the following in my /boot/config/go file. I also ran all it manually once # Configure the Bluetooth driver sudo curl -L https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_config -o /tmp/rtl8761bu_config.bin sudo mv /tmp/rtl8761bu_config.bin /lib/firmware/rtl_bt/rtl8761bu_config.bin sudo curl -L https://raw.githubusercontent.com/Realtek-OpenSource/android_hardware_realtek/rtk1395/bt/rtkbt/Firmware/BT/rtl8761b_fw -o /tmp/rtl8761bu_fw.bin sudo mv /tmp/rtl8761bu_fw.bin /lib/firmware/rtl_bt/rtl8761bu_fw.bin # Start Bluetooth /etc/rc.d/rc.bluetooth start Then I had to unplug the usb device, plug it back in and running some combination of the following made it work /etc/rc.d/rc.bluetooth stop /etc/rc.d/rc.bluetooth start sudo bluetoothctl Quote Link to comment
God_TM Posted August 11, 2022 Share Posted August 11, 2022 I tried this and can't get it to work. In home assistant, it has an error on the integrations page for the bluetooth integration: Retrying setup: Failed to start Bluetooth: adapter 'hci0' not found What exactly do you have passed in to the container? I have the path /var/run/dbus pointed to /var/run/dbus AND I have the device /dev/bus/usb/003/013 (as that's what's showing up for the bluetooth adapter in Tools > System Devices).

Adding these lines to the end of your go script right after moving the files into /lib/firmware/rtlbt and before running `/etc/rc.d/rc.bluetooth start` should mean you don't have to mess around unplugging/replugging the adapter after a reboot.
