I'm trying to sniff packets with wireshark by varying the connection interval and supervision timeout of my ble application. I see that with lower connection intervals i'm able to do this. The test was performing good util the values CI=1000ms supervision timeout = 2010. If I increase these two values to CI=2000ms and supervision timeout=4010 then wireshark is not able to sniff my ble communication. It sniffs some packets but it stops after some seconds. Should i change something in the wireshark settings to make me able to sniff packets also with higher connection intervals?

Sniffing process stops after connection parameters update has been performed.

What sniffer hardware do you use?

Hi, I’m using a nRF52840 USB dongle
