Describe the bug

The samples find_sensors and get_data_for_sensors result in the error in the title.

Finding RuuviTags. Stop with Ctrl+C.
Start receiving broadcasts (device hci0)
FYI: Calling a process with sudo: hciconfig hci0 reset
Can't get device info: No such device
Problem with hciconfig reset. Retry reset.
...

Using the regular hcitool lescan works fine and the RuuviTag is discovered:

sudo hcitool lescan

LE Scan ...
D4:22:5B:5B:98:C2 (unknown)
D4:22:5B:5B:98:C2 Ruuvi 98C2
37:2D:59:53:25:BD (unknown)
7A:90:D0:D9:0C:6A (unknown)

Looking for this specific RuuviTag via this module also fails

from ruuvitag_sensor.ruuvitag import RuuviTag

sensor = RuuviTag("D4:22:5B:5B:98:C2")

# update state from the device
state = sensor.update()

# get latest state (does not get it from the device)
state = sensor.state

print(state)

Can't get device info: No such device
