Wireshark nRF Sniffer com interface error

[Sylvain Mariteau]

Hi, i am trying to set up a BLE sniffer with a DK52832 board purcahsed for that purpose. I have encountered an issue with wireshark to capture from the interface of the board.

First,

I previously installed the dev tools, from VS Code the device is properly detected (VCOM0 on COM9) with JLink OB from which  i flashed the blinky test sample binary.

From the Programmer tool, i can select the target and erase/flash the  DK with the binary sniffer_nrf52dk_nrf52832_4.1.1.hex

--------------------------

14:01:49.175

Using nrf-device-lib-js version: 0.4.13

14:01:49.175

Using nrf-device-lib version: 0.12.8

14:01:49.176

Using nrfjprog DLL version: 10.16.0

14:01:49.176

Using JLink version: JLink_V7.66a

---------------------------

My machine runs under Windosw 10.

I installed Wireshark 4.0.1 with the Sniffer plug-in (i followed the instructions provided by Nordic) which has never detected the com interface.

I installed the previous stable version 3.6.9, the interface nRF Sniffer for Bluetooth LE COM9 is displayed, however when i start the capture i have errors pop-ups as shown in snapshot below. Sometimes, the interface is not displayed (detected),  i have to close/reopen Wireshark.

(Error by extcap pip:FIFO does not exist!)

(nRF Sniffer for Bluetooth LE could not find interface: COM9)

I have reinstalled Wireshark along npcap. I covered also the troubleshooting section from the doc nRF_Sniffer_BLE_UG_v4.1.x.pdf.

I have not updated JLink to the latest version as a installed the versin expected by Programmer app.

Has someone encounted the same issue with a fix, or could someone provide successful setup (combo wireshark/Jlink version)? I continue to investigate from the error info but without success so far.

Best regards,

Sylvain

Is there a fix on the way for this? I've run across the same issue.

I have an nRF52840DK with nRf5340 onboard debugger and was getting this error.

I connected the USB to the other USB port labelled "nRF USB" (J3) and was able to sniff.
