How to switch BLE sniffer mode to listen specific devices?

vhang

Hi.

I'm enabling a BLE sniffer on rRF52840 DK to listen to packets between Windows and the other one BLE board, I can get advertising packets but Wireshark can't switch to capture the specific devices packets after I select the device from the list, it always keeps capturing advertise packets, could I know if there is an additional step I should do?

The BLE sniffer version is 4.1.0 and Wireshark is 3.6.0.

Thanks

    Hi

    It's nRF52840 DK 2.0.1 , and I updated the hex on SES and J-Link dll is v7.6b, thanks.

    Hi again Vhang, 

    I suspect that there could be something wrong with UART communication (the board can't receive UART command from PC, but PC can receive UART data from nRF52 DK). 

    Please try to test using an UART example in the SDK. 

    Also please try to test using different USB port on the PC. If you use a nRF52840 dongle it would most likely work as it doesn't use the same UART peripheral but using USB CDC instead.
