Power Supply used: Official power supply

USB Devices connected: PS4 Controller (temporary for testing)

Hello, yesterday I updated everything on my Pi 400. After that, my Sony PS4 controllers were not recognized anymore. I tried to pair them again, but not a single BT device is shown. Normally there were tons of BT devices visible. I checked another SD card with a different OS to ensure that the bluetooth modul on the Pi is working in general and it did. I searched the web and found a solution to "sudo apt-get update/upgrade" the Pi by SSH. This did not help either.... Is there anything I can do or do I have to wait that it will be fixed with an update? Thanks in advance..... TOBI

Just to make sure the BT radio is not 'soft' blocked, run:

sudo rfkill list all

and post the output. Check that the Bluetooth system/service is started by running

systemctl status bluetooth

If it's running, it should show something like this:

 systemctl status bluetooth
● bluetooth.service - Bluetooth service
     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)
    Drop-In: /etc/systemd/system/bluetooth.service.d

Now after another upgrade it seems to be running again. BT devices are visible again and I could successfully pair the PS4 controller again. Thanks
