The nRF sniffer is not listed in the Wireshark interface.

[PrasannaKumar]

Recently i have purchased nrF51 Dongle.

Am using Windows 10 (64Bit OS) on my PC.

1. installed nrfgostudio_win-64_1.21.2_installer.msi setup for flashing

2. installed "JLink_Windows_V616c.exe " as well.

3. But used nrFGOStudio and flashed the Dongle with nrf_sniffer_2.0.0-beta-1_51296aa\hex\sniffer_pca10031_51296aa.hex

4. Installed Wireshark version Wireshark v2.4.2

5. Referred the "nRF_Sniffer_UG_v2.1.pdf" 

Section 2.0  Setting up the nRF Sniffer 

Followed all the steps 1 to 8 mentioned under the Install nRF Sniffer heading

Question 1 :Still nRF sniffer is not listed in the Wireshark interface.Please help me.

Question 2: There is no clear steps how to run the sniffer using the beta version of the Python. if i try to run the "nrf_sniffer.py"

C:\Users\20036863>nrf_sniffer.py
Traceback (most recent call last):
File "C:\Users\20036863\nrf_sniffer.py", line 62, in <module>
from SnifferAPI import Sniffer, myVersion, Logger, UART
ImportError: No module named SnifferAPI

if i try to install the package "SnifferAPI"

C:\Python27\Scripts>pip install SnifferAPI
Collecting SnifferAPI
Could not find a version that satisfies the requirement SnifferAPI (from versions: )

nrfsniffer200beta312oct20181c2a221.zip included script "extcap/SnifferAPI/UART.py" is changed baud-rate of the opened serial port.

But, this way is not as expected on macOS and Windows.

I made patch for UART.py

It works well if you can patch follow.

The baudrate change is to work around issues in the Jlink OB COM port for the DKs. I would leave it as it stands.
