after i got my wifi working (RLT 8822BE wireless problems) I still got problems with Bluetooth. It is the same device as for wifi, the Realtek RTL8822BE.
I installed the kernel 4.14.
Somehow its there. As the relevant part of
$ sudo lshw
shows:
*-usb:1
description: Bluetooth wireless interface
product: Bluetooth Radio
vendor: Realtek
physical id: 5
bus info: usb@1:5
version: 2.10
serial: 00e04c000001
capabilities: bluetooth usb-2.10
configuration: driver=btusb maxpower=500mA speed=12Mbit/s
So - i dont know what to do. I found that:
https://github.com/torvalds/linux/commit/1110a2dbe69831abdcf119c3a9a4c4ef2d0905f8#diff-73c18c51833f458295d18481beb9507aR37
but have no clue what to do with it...
Can you help me?

Check, whether the kernel you are using contains the patch. If not, a newer kernel is needed. If the kernel contains the code, install firmware for your bluetooth device and reboot.

Actually the problem might be that you install doesn't have the firmware for bluetooth, in terminal do
cd /lib/firmware/rtl_bt
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_config.bin
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_fw.binThen shutdown and boot

Actually the problem might be that you install doesn't have the firmware for bluetooth, in terminal do
cd /lib/firmware/rtl_bt
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_config.bin
sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/rtl_bt/rtl8822b_fw.binThen shutdown and boot

Check, whether the kernel you are using contains the patch. If not, a newer kernel is needed. If the kernel contains the code, install firmware for your bluetooth device and reboot.

Thanks for answering! Unfrtunately I dont know how to check if the kernel contains the patch. And which patch should I search?

I have the same problem using kernel 4.18.7-arch1-1-ARCH in ArchLinux. The firmware files from @Jeremy31's answer are already present. Machine is a ThinkPad A485
