Unable to get "STM32WB sniffer interface" on Wireshark for sniffer program

[SoumadeepDe]

I am trying to make sniffer for STM32WB BLE application work, (ref: https://wiki.st.com/stm32mcu/wiki/Connectivity:STM32_Sniffer_for_BLE_Setup_guide). I am stuck at step 4.1. I am unable to get "STM32WB sniffer interface" on Wireshark. I tried uninstalling and reinstalling all software, but no luck.

Thanks in advance for help!

Hi,

Just to confirm, have you properly programmed your board(s) (step 3)? Are they properly connected to the PC and the COM port recognized?

Hello Joé,

I looked into the device manager. I see that "STMicroelectronics Virtual COM Port (COM7)" shows 

This device cannot start. (Code 10)

{Operation Failed}
The requested operation was unsuccessful.

Is this the problem? I tried re-programming (both firmware and stack) the MCU and re-installing Wireshark, but no luck.

Please help!

Regards
