This is the post where I took the idea from:
Maybe check, if necessary, the final part:
There is still the possibility to use bluetooth (even after blacklisting) by manually modprobing the bluetooth modules. You can use the command below to test if wifi/bt can function properly together after login.
To start bluetooth temporarily, (only lasts one session):
sudo modprobe btusb; sleep 2; sudo modprobe btrtl; sleep 2; sudo systemctl start bluetooth;
Another thing you could do is to test a few other kernels (e.g. linux-lts and linux-mainline), always along with the relevant headers.
