It looks like the last discussion of Sniffer on Devzone was 2-3 yrs ago.
I’ve ordered the nRF Dongle and will download the Windows-based nRF Sniffer app.
i can run this with WireShark on a Windows VM on my Mac, though I would like a Mac OSX option.
- Any news on that front?
- Any way the Bluetooth hardware built into the MacBook could serve a Mac Sniffer app?
thanks!
Still looking for a solution here. I think a few others are having the same trouble.
Martin Lesund, what is the next steps?
Can you summarize your versions so I can look at it.
OS Version:
Wireshark version:
Python version:
Pyserial version:
Segger jlink version on PC:
Segger jlink version or build date on the jlink emulator on nRF5x-DK:
nRF Sniffer version:
PCA board number:
=
Python 32 bit or 64 bit:
Use:
import ctypes
ctypes.sizeof(ctypes.c_void_p)
8 -> 64 bit
4 -> 32 bit
Thanks for working on this, David Edwin!
I've copied the contents of your new code into the ...\extcap folder
no change in visibility of the interface in WireShark.
I ran through the "Troubleshooting" steps in nRF_Sniffer_User_Guide_v2.1.
All steps gave appropriate success results, except "screen port 460800" (same blank, unresponsive screen) and WireShark - with no evidence of the interface.
I'm still open for a screen-share - 24/7.
Thanks again!
Dave
Can you try the screen option on all the the DKs that you have, I see that a PCA10031 and a PCA10040 were mentioned.
OK. I'll try that tomorrow (Tuesday US Central time) with:
- Python 2.7.14
- pyserial (3.2.1)
- SEGGER J-Link Commander V6.16c (Compiled Jun 16 2017 18:19:39)
DLL version V6.16c, compiled Jun 16 2017 18:19:20
- WireShark Mac OS Version 2.4.5
In separate sessions, I'll use each device (nRF dongle-PCA10031 and DK-PCA10040) and flash them using the appropriate parameters in JLINKEXE to "erase..." as in the Sniffer 2.1 User Guide.
Then in OSX Terminal, I'll run "screen <port> 460800"
and report the results.
Have I got it?
Thanks
OK, I've run the above with no luck on either board.
I'm wondering where to go next.
I've been through the steps many times.
Are others experiencing this problem?
Is so, what is your environment?
I was having issues with Wireshark not showing the extcap interface in it's UI on Mac OS X 10.13.5, even though the files were in the correct location, inside the .app /Applications/Wireshark.app/Contents/MacOS/extcap/
While trying to debug the issue, i decided to run wireshark directly from my shell to see any possible output via /Applications/Wireshark.app/Contents/MacOS/Wireshark
Turns out, this was enough to get nrf_sniffer.py to load, so if you've been having trouble getting it to load, it might be worth running the executable directly from Terminal.app
I suspect it has something to do with environment variables that Wireshark inherits from the shell, but haven't debugged further.
EDIT: Turns out, the best way to fix this so regular app launches work was to change the shebang at the top of nrf_sniffer.py to point directly to your local python2 instance. For me, this was #!/usr/local/bin/python2

Wow! This appears to be the magic bullet. With that one change to the nrf_sniffer.py file, I now see this when launching Wireshark.
I'll check this more thoroughly tomorrow, end-to-end, and with the otherwise-default installation options.
Thanks a million! I'll validate the answer after that checking.
Would this have been caught if the the "python --version" as requested in nRF Sniffer User guide v2.1 was verified ?
Install nRF Sniffer Step 6.
C:>python --version Python 2.7.x
My python version is (and has been throughout) 2.7.14 as display now below:
Davids-MacBook-Pro-2:~ davidelvig$ python --version
Python 2.7.14
I posted that step way back ups in this thread.
The only change I made recently, based on the post by @Richard was to edit the top of nrf_sniffer.py
I've been delayed in my end-to-end testing, but still plan to do that in the coming days
Thanks, all for your posts!
Can you also provide the output of "which python" ?
Python version
Davids-MacBook-Pro-2:~ davidelvig$ python --version
Python 2.7.14
Which
Davids-MacBook-Pro-2:~ davidelvig$ which python
/Library/Frameworks/Python.framework/Versions/2.7/bin/python
