Trying to connect to bluetooth device, can't see it at all (but phone can)

[Ralf Mardorf]

Hi,

I've got no experiences or knowledge related to Bluetooth on Linux, but
the Arch Wiki provides a few pointers related to Bluetooth.

"Pairing
Note: Before using the Bluetooth device, make sure that it is not
blocked by rfkill." - https://wiki.archlinux.org/title/bluetooth#Pairing

"Many laptops have a hardware button (or switch) to turn off the
wireless card; however, the card can also be blocked by the kernel. This
can be handled by rfkill. To show the current status:

$ rfkill

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

If the card is hard-blocked, use the hardware button (switch) to unblock
it. If the card is not hard-blocked but soft-blocked, use the following
command:

# rfkill unblock [...]" -
https://wiki.archlinux.org/title/Network_configuration/Wireless#Rfkill_caveat

"Device does not show up in scan

Some devices using Bluetooth low energy do not appear when scanning with
bluetoothctl" -

Regards,
Ralf
