Bluetooth was working fine on my laptop (Acer Aspire V17 Nitro) running Ubuntu 18.04, until I used Suspend for the first time and woke it up again. It doesn't detect any devices anymore.
Things I've tried:
Rebooting
Disabling & enabling bluetooth
Restarting the bluetooth service
Re-installing these packages:
bluez
gnome-bluetooth
pulseaudio-module-bluetooth
Running
rfkill list
:0: hci0: Bluetooth Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no
Booting into a live USB and enabling bluetooth there (it doesn't detect any devices there either)
Does anyone have any other ideas? The fact that it failed while suspending or while waking up from a suspend might be a clue.
