Hi, I am sorry I haven't come back to you on this. Are you still having trouble? Perhaps you can check if the sniffer firmware is flashed correctly on the DK? Or test with another DK or the dongle?

What does the output log looks like when you used the 'nrfjprog' command to flash the sniffer firmware to the DK?

Best regards,

Marjeris

Marjeris,

Thank you for the information. When I leave SW9 on VDD, the LED1 will blink even with the USB cable attached to the port on the long side of the DK (as pictured). It also blinks correctly with the cable in the port. However, in the picture, it appears SW9 is on USB - when I use that position, LED1 does not blink, event with the USB cabled plugged into the long side.

Either way, I still don't see the interface appear in Wireshark, even after copying the bat and py files. Anything else I can try?

Hi,

First double check that you meet all the requirements for Windows:

Required software

Wireshark 2.4.5 or newer
Python 2.7, Python 3.6 or newer
Python packages:
- Windows: pySerial Python package from pip
nrfjprog – available in nRF5x Command Line Tools
Sniffer firmware binary – see Obtaining the firmware

Make sure the python installation directory is in your PATH enviromental variables.

Make sure the sniffer software is correctly flashed to the nRF52840 DK. Could you attach both the nrfjprog command and output from the command window when you flashed the software? It should look something like this.

C:\nordicsemi\Tools\nRF-Sniffer-for-802.15.4\nRF-Sniffer-for-802.15.4\nrf802154_sniffer>nrfjprog --chiperase --family NRF52 --program nrf802154_sniffer.hex --reset
Parsing hex file.
Erasing user available code and UICR flash areas.
Applying system reset.
Checking that the area to write is not protected.
Programming device.
Applying system reset.
Run.

LED1 should start blinking.

[quote user=""] Also, is there a way I can connect to the Nordic DK by RTT or serial to view logs and see if the FW is uploaded correctly?[/quote]

Unfortunately this FW will not output any log messages, but LED1 should be blinking if the software is flashed correctly and running.

Then change the USB cable from the JLINK USB connector over to the nRF USB connector.

Remember to power on the board, SW8 set to ON, wait a couple of seconds and LED1 should start blinking again and you should see your board appear in the Capture menu on Wireshark.

Best regards,

Marjeris
