My once functioning bluetooth seems to be dead on my pi 400. bluetoothctl show & bluetoothctl power on both report “no default controller available”. I tried reinstalling brcm-patchram-plus, sudo systemctl restart attach-bluetooth.service and sudo systemctl restart bluetooth.service, but no luck. I found this post from the archlinux forum that might be related and below I have provided output for some of the commands suggested in that thread.
I’m a layperson when it comes to this so unfortunately the best I can do is provide some information potentially useful for troubleshooting. Some output that may be of interest: bluetoothctl saying “No default controller available”, btmgmt info reporting “Index list with 0 items” (not detecting a bluetooth device?) and the “Key file does not have key” from bluetoothd as reported by systemctl and journalctl. Appreciate any assistance on this. Thanks.
