hcitool lescan returns an I/O error on Manjaro

I'm trying to connect MX Master 3 to my computer.

OS: Manjaro 21.2.1 Qonos
Kernel: x86_64 Linux 5.10.89-1-MANJARO
Computer: Dell XPS 7390

I tried:

sudo hcitool lescan

which gives:

Set scan parameters failed: Input/output error

rfkill list all gives:

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

and hcitool dev gives:

Devices:
        hci0    84:1B:77:B4:B4:D1

Things I have already tried:

hciconfig hci0 down
hciconfig hci0 up

sudo systemctl restart bluetooth.service
sudo systemctl restart dbus.service
Solution

  • Inside bluetoothctl:

    menu scan
transport le
back
scan on

    This resolved the problem.
