nRF Sniffer on nRF52840 Version 3 installation error

[cycledude]

Hello,

I am working on a Windows 10 pc. python 3.7 is installed and the requirements.txt has been installed successfully and I have the most current pyserial installed

I have successfully installed firmware hex code on the nRF52840 dev board.

Copied the the contents of Sniffer_Software/extcap to the Wireshark extcap folder

When I run the nrf_sniffer_ble.bat --extcap-interfaces as per the pdf instructions I receive an error.

This results in the following error:

c:\Program Files\Wireshark\extcap>nrf_sniffer_ble.bat --extcap-interfaces
Traceback (most recent call last):
File "c:\Program Files\Wireshark\extcap\nrf_sniffer_ble.py", line 52, in <module>

from serial import SerialException
ImportError: cannot import name 'SerialException' from 'serial' (C:\Users\WORK\AppData\Local\Programs\Python\Python37\lib\site-packages\serial\__init__.py)

Can you please help?

Thanks

Hello Rick,

Did you copy all of the files and folders from the downloaded extcap folder to the wiresharks extcap folder?

Can you double check that you have the correct python version in the path when you type "python --version"?

If it still doesn't work, can you please try to install python 3.8.x? I have this installed on my computer, and I just installed nRF Sniffer version 3, and I didn't experience any problems. If that works, I will report this as a bug internally (because it says that version 3.5 or later should work).

Best regards,

Edvin

Glad to hear that it worked out. What version of python 3.7 did you use? I will report this internally to either fix the bug, or update the description/requirements.

Best regards,

Hi Edvin, I used Python 3.8.1.

Thanks again.

Hello Rick,

Sorry if I'm bothering you.

I just had a few things that I wanted to finish before reporting this internally since you had it up and running. I wanted to check whether I was able to reproduce the issue that you had with the previous version of Python. If it is, in fact, a bug, we should either update the documentation or find a fix, so that others don't need to struggle with the same.

So which version of Python did you use before you updated to 3.8.1?

Have a nice weekend.

Best regards,

Edvin

Sorry Edvin, I should have included that I was using Python version 3.7.6
