Bluetooth 'No default controller available'

I am sorry if this has been asked before, but I can't seem to find a solution that works online.

Bluetooth still worked yesterday and the problem only appeared today. When I try to power on in bluetoothctl, a message saying 'No default controller available' pops up.

I did do a full system upgrade (which contained the kernel) recently but I do not recall if it is done before setting up bluetooth or after. In any case, when I downgraded the kernel to the original version, it still did not work.

I've tried unloading and reloading the kernel module, blocking and unblocking bluetooth in rfkill, and even reinstalling all the bluetooth related packages, and no luck.

If i am not mistaken, my wireless card (Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78)) handles both WIFI and bluetooth, however, wifi works just fine.

How could I solve this problem?

I will provide any further information that is needed.

Re: Bluetooth 'No default controller available'

Hi, I experienced similar problems with mouse and keyboard bluetooth devices after updating kernel to 5.17.7. Both devices were working find before the update (kernel-5.17.6) . After update neither mouse nor keyboard were detectable/usable. E.g.  bluetoothctl gave a message saying 'No default controller available'

From the journal:

I downgraded to kernel 5.17.6. After reboot I was able to pair and connect both mouse and keyboard again and it has been working fine since then.

I don't really know if Bluetooth is closely related to kernel updates but I have noted similar problems after updates a few times before.

I have a Dell M4800 with the following packages broadcom-bt-firmware installed:

blueman 2.2.4-1
bluetooth-autoconnect 1.3-1
bluez 5.64-2
bluez-libs 5.64-2
bluez-utils 5.64-2
broadcom-bt-firmware-git 12.0.1.1105_p3.r0.g68a7a8a-1

From lsusb:

Bus 002 Device 003: ID 413c:8143 Dell Computer Corp. Broadcom BCM20702A0 Bluetooth

I usually run 'pacman -Suy' once a day, but now I am not sure how to proceed with updates.

Re: Bluetooth 'No default controller available'

Well, I encountered problems again with bluetooth and 5.17.6-kernel so I decided to update to 5.17.7 (which I had downgraded from).  The problems were still present as before.  I now removed broadcom-bt-firmware-git 12.0.1.1011_p1.r3.gc0bd928-2 and installed bcm20702a1-firmware 1201710-8  instead. After reboot it seems to deal with the problem so I got Bluetooth keyboard and mouse working again
