...no ?
years ago I couln't even dream of using bluetooth in linux; few weeks ago I found an old bluetooth dongle and now my usb speakers work just fine - even better than connecting via smartphone because plasma has sbc-xq codec easily selectable. It auto connects everytime I boot the pc, I just had to add btusb.enable_autosuspend=0 to kernel cmdline parameters
make sure you follow these guides, whicever distro you use
if it crashes, try sudo systemctl stop bluetooth.service and sudo systemctl start bluetooth.service
remember, bluetooth is a very cursed embrace-it-all protocol and may randomly crash/refuse to pair/connect unless you reset the devices manually, and this may happen with any hardware/software
