Zigbee Cli Agent Router example hangs after bdb start command

[[email protected]]

I am using nrf52840 dk for zigbee project with two xbee modules. One xbee is configured as coordinator and other as end device and nrf board is supposed to act as router. After setting channel and pan id from cli when I enter bdb start , command prompt just hangs .

Are you sure you have Python (and only one version of Python) in your computer's environment path? if you type "python --version" in a cmd window that is not opened in the same folder as your python executable?

Have you programmed the sniffer FW on your DK? Try to power cycle the DK after programming it, and plugging in the USB peripheral port (not the programming port on the DK, but the one on the long side, as it was shown on infocenter).

If it still doesn't show up, try to reboot your computer. Perhaps it is needed after installing Wireshark once more.

Yes , i have flashed the firmware using port above the coil cell.

The port mentioned in tutorial is nrf usb which is very next to buttons for sniffing and I am trying to use that port which is not connecting on windows 10 pc.

Is the DK powered? Any LEDs blinking? Try to power the DK with a separate USB cable through the programmer USB. 

Alternatively, there are some switches on the DK on which you can choose to power the DK with the USB peripheral. I believe you only need to set the nRF Power Source switch (close to the programmer USB port) to USB, but I can't double check this now. (Home office due to the pandemic , so I am using remote desktop and don't have physical access to the DK, only programming/logging).
