bluepy.btle.BTLEException: Failed to execute mgmt cmd 'le on'

[mulysatest]

First of all thank you for your super great effort and support on this project.

I managed to run the demo code successfully, however once I tried to run findMambo.py I got this error. Do you got any suggestion to solve it? I am using Linux tinkerboard 4.4.71+ on Asus Tinker Board.

~/pyparrot$ python findMambo.py 
Traceback (most recent call last):
  File "findMambo.py", line 27, in <module>
    devices = scanner.scan(10.0)

I managed to solve problem using this command

sudo setcap 'cap_net_raw,cap_net_admin+eip' PATH/TO/LIB/python3.5/site-packages/bluepy/bluepy-helper

in my case

sudo setcap 'cap_net_raw,cap_net_admin+eip' /usr/local/lib/python3.5/dist-packages/bluepy/bluepy-helper
