Hello ArtemS,

Thank you for the feedback. I will forward this to the developers as well.

Best regards,
Karl

For those who interested, here is the modified .hex.

Dmitry suggestion worked for me. However, sniffer works in Wireshark only, while SnifferAPI doesn't recognize it.

Hi,

in Windows 10, serial driver is loaded automatically for any device with class_02&subclass_02 in device descriptor (VID and PID doesn't matter). For Windows 8 and older, you need matching inf/cat files, and it will not install nordic_cdc_acm.inf as it has no VID/PID that match sniffer firmware.

As a quick fix, you can try to modify PID directly in hex file by changing two bytes at line 4085 (though I believe there should be some correct way):

:100EDC00120100020000004015191A52030201020F

Dear Karl, I am sure this is not Hw issue. The dongle just enumerates with PID_522A and driver which you deliver is for PID_521A. And that does not match. If I add this line:

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

To the inf file then windows finds the driver correctly but can not install it as hash file (.cat) was generated using different inf file and windows blocks it.

Could you please check what PID you see on your device? If PID_521A then it means you have different firmware. If so, could you please provide it?

The question is also what MBR should be written? Does it matter? I was using the original which was written at production later I reprogrammed it some different one found in SDK (for 10059), but it did not change anything.

Best Regards
PAF

Thank you for clarifying, PAF.

I have tried this on my end, using Windows 10, and I am unfortunately not seeing this issue.
To rule out the hardware being at fault, do you have access to a non-Windows 8 PC which you could test the sniffer on?
I will discuss this with a colleague that knows more about windows 8's drivers than me on Monday.

Best regards,
Karl

Hello Karl,

I went exactly the procedure shown in Sniffer Instalation guide (even three times).

1. installed nRF connect
2. installed Programmer
3. downloaded nRF Sniffer Bluetooth LE (3.1)
4. chosen nrf_sniffer_for_bluetooth_le_3.1.0_7cc811f\hex\sniffer_nrf52840dongle_nrf52840_7cc811f.hex file
5. pressed write
6. after reboot device enumerates with VID_1915 and PID_522A and can not find the valid driver.

Hope this helps.

Best Regards
PAF

Hello again PAF,

Could you also confirm for me that you have followed all the steps of the Sniffer installation guide?
Could you also specify exactly how and what you programmed the nRF52840 Dongle with?

This might seem trivial, but I would like to rule out the installation as a potential error source.

Best regards,
Karl

Hello Karl,

unfortunately I tried that before and it did not work that is why I raised that ticket. The device enumerates with VID_1915 and PID_522A and the driver you are referring to is VID_1915 and PID_521A so Windows does not find the proper driver when pointing to SDK/examples/usb_drivers. Any other sugestions?

I used latest SDK I found (nRF5_SDK_17.0.2_d674dde)

Best Regards
PAF

Hello PAF,

I am sorry to hear that you are having issues with this.
The following should not be necessary with windows version later than Windows 7, but if you could please give the following a try, and let me know if this resolves your issue:

If you are running Windows 7, on first run CDC ACM driver installation is needed. To install the driver on Windows 7, follow these steps:

Open Device Manager
Right-click the development kit (look for the name "nRF52 ..." depending on the example)
Click "Update Driver Software..."
Click "Browse my computer for driver software"
Click "Browse..." and choose the folder SDK/examples/usb_drivers
Click "Ok"
Click "Next"
Click "Install"
Click "Close"

As mentioned I have only ever heard of this being an issue with Windows 7 and older, but let us give this a try.

Looking forward to resolving this issue together!

Best regards,
Karl
