Since today, I am no more able to use my bluetooth devices... I have instead this error:
"bluetooth: hci0: unexpected EPATCH signature!"
And KDE displays me the following thing:
I am wondering what is the meaning of this?
Yesterday, I have made an update with the following content:

Do you see something which could break bluedevil? Should I report a bug on archlinux? On KDE? Elsewhere?
Cheers,

No one has any clues? It was working great before, even better than with windows. And now it is just not activable:
~ » bluetoothctl
[bluetooth]# power on
No default controller available
I have seen the same error on these gitlab issues :
https://github.com/lwfinger/rtl8723au_bt/issues/32
https://github.com/lwfinger/rtl8723au_bt/issues/18
But I am not using this package, so it is not helping me at all!

Got the same error since the last kernel update.
Output of dmesg:
[ 10.598806] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000b lmp_ver=06 lmp_subver=1200
[ 10.598807] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723a_fw.bin
[ 11.152410] Bluetooth: hci0: unexpected EPATCH signature!
Maybe there have been some modifications with the driver, do you have the same device? (rtl8723a)
Edit:
I installed the driver from https://github.com/lwfinger/rtl8723au_bt and bluetooth works again for me.

Same band wagon.
Actually the adaptor doesn't show up at all.
do it good first, it will be faster than do it twice the saint

Got the same device too.
[ 1.684290] Bluetooth: hci0: rtl: examining hci_ver=06 hci_rev=000b lmp_ver=06 lmp_subver=1200
[ 1.684292] Bluetooth: hci0: rtl: loading rtl_bt/rtl8723a_fw.bin
So installing this driver looks like a good solution, I will try to install manually the driver today. I hope it will just not break anything with the next updates.
Someone has an idea where to report this issue in order to be taken into account?
Offline
I confirmed that installing this driver solved the issue however.

Keep in mind, that whenever you update the linux kernel, you will have to manually install the drivers again.
I was also thinking of reporting the problem, because everything worked just fine before the kernel update, but I had no time today.
I think the drivers/bluetooth section at https://bugzilla.kernel.org is a good place for a report.
Edit:
Realtek hardware is actually a pain in the ass in linux, for example my wireless card is also a realtek one.
In Windows, I have almost perfect wifi signal, but on my arch installation it's only about 50 % signal quality.
Installing the drivers from the site i mentioned previously also didn't help, so i have to live with it I guess.
Edit2:
I ended up installing the linux-lts kernel, because I had troubles even after I installed the driver from lwfinger mentioned above.
The bluetooth device was detected fine, but I had troubles, for example when powering on the device with bluetoothctl.
With the lts kernel, everything is working fine.
