Setting up the nrfSniffer

[Den]

Hi,

I am following the nRF_Sniffer_UG_v2.2.pdf to setup the nrfSniffer. Wireshark does not show me my board among the interfaces. I had a look at the troubleshooting part. In part 6.1 the given tests are;

1. Run nrf_sniffer.bat --extcap-interfaces to list the interface.

2. If this exits with a python error, verify that python.exe can be run from the command line c:>python.exe --version, where the Python version is the same as Section 1.2 “Required software” on page 2.

My setup passes the second test. I see the version as 2.7.16. However it fails the first test; the outcome is nrf_sniffer.bat is not recognized as an internal or external command . I think the step I am missing is (correct me if I am wrong);

"For Windows - Verify that the path used for python in the nrf_sniffer.bat file correctly points to the required version as stated in “Required software“ on page 2."

Can someone please explain what this means?

Also is requirements.txt in pyserial-master supposed to be empty?

Thanks.

Hi.

"For Windows - Verify that the path used for python in the nrf_sniffer.bat file correctly points to the required version as stated in “Required software“ on page 2."

 It means that you have to verify that it is Python 2.7.xx that is running the nrf_sniffer.bat file:

@echo off
python "%~dp0nrf_sniffer.py"  %*

(The content of the file above).

Have you checked this?

Also is requirements.txt in pyserial-master supposed to be empty?

 Looks empty on GitHub, you can install it with pip to be sure;

python -m pip install pyserial

Best regards,

Andreas

Hi Andreas,

Thanks for your assistance.

I can confirm the the content of the nrf_sniffer.bat file's content is as you showed. 

Yes, I have checked the stuff under 6.1

I am not sure if pyserial has been installed correctly. How can I make sure of that. I am not experienced in using the cmd terminal. So I will be happy if you can please direct me as required. I have tried to installed pyserial as you said and the output is;

C:\Users\Denin\Desktop\pyserial-master>python -m pip install pyserial

Hi,

Both host and emulator firmware are now dated 2017 June 13 10:37. I deleted the previous jlink version. 

Unfortunately the behavior is the same, it stops after a while. 

I have also tried the sethwfc force command but I think its not accepted in this version. 

Is there anything else I can try?

Best regards,

Denin

Hi.

Unfortunately, I have no other suggestions to add.

I have talked to the developer and he is aware of the issues your facing and working on fixing those issues for the next release.

I hope this is of some comfort.

Best regards,

Andreas

Hi Andreas,

I am sorry to hear this.

If we have tried every possible way and if the developer is aware of these, does this mean that I can be assured of that the problem is not caused by my set up? So buying a nRF52840 DK to use as sniffer instead of my custom board would not help?

Best regards,

Denin

Hi.

I cannot exclude the fact that your custom setup might affect the issue. It could be possible that the sniffer is more stable on one of our DK's or Dongles.

Is the email you're registered with on DevZone you're primary email?

I could arrange a Dongle for you. I will send you an email.

Best regards,

Andreas

Thanks for your kind support Andreas. I will update this post when I give it try with nRF52480 DK.
