- Dell Precision 5570[1] has the CNVi wireless module on an Alder Lake-S platform. The wireless module needs the correct firmware[2] for bluetooth to work. Based on Dilyn's comment #18[3], it's unclear if the firmware has been loaded on Core. Please check dmesg and see if it loads the intel/ibt-0040-0041.* firmwares.

- Plase include the following information in the following tests, which will help the team identify the root cause quicker
$ sudo grep '' /sys/class/dmi/id/product_* /sys/class/dmi/id/*_serial
$ sudo cat /etc/cpuinfo
$ snap info bluez && snap connections bluez # version of bluez (even
it's not been updated for a while, but we may not remember what it is
after a while)
$ snap info pc-kernel
$ sudo lspci -nn -vvv -k
$ sudo lsusb -vvv
