nRF52840 dongle as a sniffer to capture BLE packets in Wireshark.

[Abdul0]

I am using an nRF52840 dongle as a sniffer to capture BLE packets in Wireshark. Recently, I’ve noticed that the captured files are approximately half the expected size, and I’m not sure what is causing this issue.

This setup has been very reliable for the past two and a half years, and I haven’t made any significant changes to my configuration.

Has anyone experienced a similar issue or have any suggestions on what might be causing this?

Hmm, this sounds very strange, and I can't say I've seen or heard of something similar in the past. Can you upload a sniffer sample for us to take a look at, then I can also loop in the nRF Sniffer developers to see if they have any ideas to what this odd behavior could be. And just to make sure, this always occurs on your side now, no matter what traffic you are sniffing? Do you have multiple Dongles where you see this, and have you tried erasing and flashing the nRF Sniffer firmware again on a Dongle you're seeing this on to see if it still happens?

Can you also try with the nRF Sniffer firmware in nrfutil which is the latest version of the nRF firmware to see if it's reproducible there as well?

Best regards,

Simon

I have the exported csv version of the Wireshark trace, one example, look between event counter 126 and 128 and NESN and SN this indicates maybe sniffer missing....let me know if I can provide more info test10.csv
