https://devzone.nordicsemi.com/f/nordic-q-a/62799/nrf-sniffer-using-nrf52840-dk-wireshark-interface-problemHi, I would like to use the nRF52840 DK as a BLE Sniffer. I followed nRF Sniffer for Bluetooth LE v3.0.0 User Guide but cannot run the DK as what is expected. I have uploaded sniffer_pca10056_129d2b3.hex in the DK using the nRF Programmer. en-USTelligent Community 13Fri, 19 Jun 2020 12:09:28 GMThttps://devzone.nordicsemi.com/thread/255961?ContentTypeID=1Fri, 19 Jun 2020 12:09:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9e77c02-5e5a-403f-a370-7f79469a2524Hung Bui<p>Hi Johnny,&nbsp;</p> <p>Could you tell which version of wireshark you used ?<br /><br /></p> <p>When you open wireshark do you see this in the loading screen (take ~30s on my computer) ?</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/829x208/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-68112f3943eb4deb9d8a16df7fde583e/pastedimage1592568469349v1.png" /></p> <p>Have you tried to test UART on the PCA10056 board ? Any UART example in the SDK should work. We need to verify that UART communication is ok.&nbsp;</p> <p>When you run the firmware do you see LED1 blink rapidly ?&nbsp;</p><div style="clear:both;"></div>
