Title:
hcitool lescan says 'Set scan parameters failed: Input/output error'
Status in bluez package in Ubuntu:
New
Bug description:
Hi,
after some testing with Ubuntu 20.04 beta I couldn't get hcitool
lescan working. I get the following error:
hcitool lescan
Set scan parameters failed: Input/output error

It is not hardware related, since I get the same error with a USB
bluetooth dongle:
hcitool -i hci1 lescan
Set scan parameters failed: Input/output error
hcitool scan is working fine on both devices; bluetoothctl is also working
and able to find ble devices.
I would normally prefer bluetoothctl, but I got a software which is based on
hcitool.
dmesg shows this errors:
