nRF52 Dongle as sniffer

[Malcolm]

I have programed the nRF52 dongle as sniffer using the hex file from the 3.1 release using nRF Connect programmer. When I plug dongle I expect a COM port to be created in Windows, but this is not the case. Consequently it is not being detected in Wireshark.

I appear to be missing an INF file with USB\VID_1915&PID_522A&MI_00. The inf file in the SDK has

[DeviceList.NTx86]
%NORDIC_CDC_ACM_EXAMPLE%      =DriverInstall, USB\VID_1915&PID_520F&MI_00
%NORDIC_BLE_UART_EXAMPLE%     =DriverInstall, USB\VID_1915&PID_521A&MI_00
%NORDIC_USB_CDC_CONNECTIVITY% =DriverInstall, USB\VID_1915&PID_521B&MI_00
%NORDIC_SDFU_USB_EXAMPLE%     =DriverInstall, USB\VID_1915&PID_521F&MI_00

I have added the line

%nRF Sniffer for BlueTooth LE%     =DriverInstall, USB\VID_1915&PID_522A&MI_00

and this is now working.

1. MBR must be present to ensure that the sniffer loads in the correct location

2. INF file needs to have correct line to match parameters of the dongle virtual COM port

Thanks for sharing your solution here! I did not know you had to install the driver manually. Are you using Windows 10?

[Malcolm]

I continue with WIN 7 with classic theme. It is a better programmers UI (less screen lost, quicker to get to programs).

The INF file I updated comes from the SDK.

ok, thanks for confirming. That explains the issue, the driver installation is automatic on windows 10, but not on windows 7.
