nRF51 BLE Sniffer and Wireshark Not Filtering/Tracking

[Dave_couling]

Hi guys,

I installed the latest nRF Sniffer software and use Wire Shark 1.10.14. My JLink driver is 6.12A (I'm not able to access any of the earlier drivers). The command line part works fine. I can see my peripheral in the list. However when I press "w" to open WireShark, Wireshark opens and displays the advertisements of all peripherals not just the one I numberically selected. Obviously then, when I establish a connection, Wireshark doesn't track the connection session, and instead simply continues to scan ALL advertisements. Why is Wireshark not filtering properly? I've never had issues with this previously. Now I'm with a new machine, I can't get this tool to work. Its pretty vital to my development right now, hope someone has gone thru this issue before.

Thanks guys

Hi,

You can download Segger Jlink v5.10n here.

Please follow the video guide here.

You need to select the device you want to follow the connection. You can use arrow button up and down (or press the number) and press enter to select the device.

If you don't select a device, then it will capture only advertising packet and fail to follow one connection.

Thanks Hung, my issue is that after I select my device and open Wireshark, Wireshark still reports other devices....

The updates JLink driver didn't resolve the Wireshark issue.

Have you made sure you update the Segger's firmware on the board ? You need to use Jlink Configurator, then right click on the board and select Replace firmware.

Got it, works now. Thanks Hung
