I have a RPI 400 running Buster release 10 and I've not connected up a bluetooth device to it in a while. Today I was working to connect a device and found that nothing was showing up in the Add Device dialog box from the bluetooth icon on the desktop. I can confirm that other computers can see the bt devices broadcasting, so even if the RPi couldn't connect, it should've seen a handful of devices which were looking to connect and nothing was showing, which led me to believe there was an underlying issue.
I tried bluetoothctl, and ran "list" and I get nothing back, which seems to indicate there's no active controller. I tried some of the systemctl suggestions around restarting bt and some others about uninstalling and reinstalling bt and none of them seemed to make a difference.
Any suggestions on how to troubleshoot and/or resolve?
When I restart the bt service with a "-d" appended in the bt service file I have this in the syslog:
and since it came up in some posts, but not sure of it's relevance, this is what the hciuart service returns for status in case its helpful:
