Error while executing code

Please let me know what i am missing. I used exact example code mentioned.

Traceback (most recent call last):
File "BluetoothSept012020.py", line 4, in

You seem to be using python2.7. I think this library is intended for python3.

[tongclement]

You need to install python3 and when running, instead of python file.py, do python3. Also when doing pip package installations, you might have to call pip3 if pip doesn't seem to work. Try googling for more information. I understand, its frustrating :D Hope it helps.

Thank you quick response. I tried python 3 also and here is new error....

from bluetooth import _bluetooth as bluez

i used pip3 install beacontools

[guptva5]

So after this error .... i installed pybluez as well using below command.

python3 -m pip install pybluez

Now i am getting different error

Did you execute this command from the readme?

# grant the python executable permission to access raw socket data
sudo setcap 'cap_net_raw,cap_net_admin+eip' "$(readlink -f "$(which python3)")"
