nRF52840 dongle not working with wireshark in windows 7

[emar]

I am trying to use the dongle as a sniffer.  I followed the following instructions to download sniffer code onto the dongle:

#### nRF52840-Dongle (PCA10059)

1. Download and install [nRF Connect for Desktop](www.nordicsemi.com/.../nRF-Connect-for-desktop).
2. Click `Add/remove apps` and install `Programmer` application.
3. Plug the dongle to USB port and click reset button to enter DFU mode. Red diode should start blinking.
4. Select `Nordic Semiconductor DFU Bootloader` device from the list.
5. Click `Add HEX file` and select `nrf802154_sniffer_dongle.hex` from `nrf802154_sniffer` directory.
6. Verify that the selected application begins at the `0x00001000` address to avoid overwriting the MBR section.
7. Click `Write` to flash the device.
8. Unplug the dongle from the USB port and plug it again. Do not click the reset button.

### Install extcap script

To find the correct installation path of the extcap utility on any system please see:
```
"Help" -> "About Wireshark" -> "Folders" -> "Extcap path"
```
Copy the provided `nrf802154_sniffer.py` script to the extcap directory.

__Note to Windows users:__ `nrf802154_sniffer.bat` has to be copied to the same directory as well.
Ensure that Python directory is included in your `PATH` system environment variable.

Installed python interpreter 3.7.7 onto Windows 7 and added to environment path.

Wireshark doesn't recognize the dongle.  I tried to install the driver:  nrfconnect_cdc_acm.inf but won't install.  The PID for the dongle fw does not match this driver.  Is there a Windows 7 driver for a VID_1915 and PID_154A?

Thanks.

I took a look at that case.  I am not using the dongle as a BLE sniffer but using as a zigbee sniffer.  I am using the correct hex file but no windows driver for it.  The instructions above was originally for Windows 10 which has a driver for the dongle to run with PID_154A.

If there is a zigbee sniffer software that will make the dongle run with Wireshark on Windows 7...  I can flash that hex file.

PCA10059  1.2.0

If I reset the dongle then the nRF Connect Programmer will recognize the dongle via COM port.  Programming that hex file, nrf802154_sniffer_dongle.hex, changed the PID while the VID remained the same and then the dongle shows up as a USB device and not as a COM port.

Those were the only instructions I found for Wireshark when I searched for zigbee on Wireshart website.  Yes I believe those instructions are for Windows 10.

I will try using the Bluetooth sniffer but what does that get me?

Thanks,

You can directly type in the baud rate in the tera term text box , like 1000000 for 1M and 2000000 for 2M.

Just tried it.  Still no stream of bytes.  My LED on dongle is blinking green.

Here is what it looks like with the inf file I created from the sample.

I finally got it to work.  The pyserial didn't install correctly. so I had to go back and install the module.  Everything is working now.

Cool. Please give an upvote. Thanks for your patience.
