Tilt2mqtt starts and stops!

[franknh-design]

Hi,

Do you know if this works with ubuntu 20.04 and the latest beacontools and phyton3.8.5?
When i phyton3 tilt2mqtt.py without sudo it starts then stops after 3 sec.
INFO:root:Started scanning
root - INFO - Started scanning
INFO:root:Stopped scanning
root - INFO - Stopped scanning

And when i try sudo i get a error:
Traceback (most recent call last):
File "tilt2mqtt.py", line 39, in
from beacontools import BeaconScanner, IBeaconFilter, parse_packet, const
ModuleNotFoundError: No module named 'beacontools'

When i try Bluetooth manual, it works:
[bluetooth]# scan on
Discovery started

Can someone help me in right direction?
