BLE Sniffer - stops sniffing packets some time after connection

[dyres004]

I am using the BLE sniffer in Wireshark (nrf 52840 dev kit board)  to attempt to capture packets between a BLE device and android phone. I am able to sniff advertising packets, choose the device, and then sniff the packets associated with the connection process. The problem is after 10-60 seconds of the connection I stop collecting packets even though from the android app I can confirm that transmission is happening currently. If I sever the BLE connection between the phone and device the sniffer usually starts picking up advertising packets again.  Any ideas how to resolve this issue?

Hi

I'm guessing the two connected devices pair somehow once they are connected, which causes your sniffer to be "thrown out" of the connection. Please check out the nRFSniffer guide and the "Sniffing a connection between paired devices" section to see how your sniffer can "join in" on the connection.

Best regards,
