nRF sniffer doesn't capture any packets

[Chandasree]

I am trying to setup NRF Sniffer for 802.15.4 using nordic board PCA10056. When the capture is started on Wireshark, the capture starts but the sniffer doesn't seem to capture any packet.

I followed the following steps to setup sniffer -
1. git clone https://github.com/NordicSemiconductor/nRF-Sniffer-for-802.15.4

2. Flash the n52 firmware with this command: nrfjprog --chiperase --family NRF52 --program <RepositoryFolder>/nrf802154_sniffer/nrf802154_sniffer.hex --reset

3. Open Wireshark -> "About Wireshark" -> Global Extcap path. Copy this file: nrf802154_sniffer.py (in the same dir as the .hex file) to /Applications/Wireshark/Contents/MacOS/extcap

4. Run nrf-Sniffer-for-802.15.4 setup.py. "sudo python setup.py install"

6. On the NRF dev board that's flashed with the firmware, switched to the nRF USB port on the long side by the 4 buttons. 

7. Open Wireshark

8. Select nRF Sniffer for 802.15.4, start capture. 

My setup is as follows:

macOS Mojave, python ver: 2.7, pyserial ver: 3.2.1, Board: nRF52 DK (PCA10056), Wireshark version: 3.2.2, firmware loaded: nrf802154_sniffer.hex

Any help is appreciated. Thanks in advance.

Hi,

It looks like you installed it correctly. Are you sure there are packet to capture in that channel?

You can select the channel by clicking the gear icon next to "nRF Sniffer for 802.15.4:/....".

All the examples from the nRF5 SDK for Thread & Zigbee are default to channel 16. Try to run for example the ligh bulb example for Zigbee under <InstallFolder>\examples\zigbee\light_control\light_bulb using another nRF52840 DK to create some traffic in channel 16.

Best regards,
