Throughput calculation with Wireshark

[WaKo]

Hi,

I want to calculate throughput rate using data that nRF52840 dongle working as sniffer captured.

Wireshark shows 'time' , 'delta time' and 'packet time'.

I think 'time' is incorrect.

For example, about IFS,  'delta time' shows 150 us but 'time' shows more than 1 ms.

・What dose 'time' means ?

・Do ’delta time’ and 'packet time' show correct time ?

Best regards

Hi

At this maximum throughput in the 2MBPS PHY and with DLE + L2CAP, the nRF Sniffer will fill its buffer rather quick, and while it sends data from the chip to Wireshark, the device will miss a few packets before getting back to listening.

Yes, you can estimate a throughput rate from Wireshark using the delta time and packet time parameters.

Best regards,

Simon

Thank you  your answer.

I understood about Wireshark.

How about nRF Connect for Desktop ?

May using it with nRF52840 dongle as a master also face missing a few packets ?

Best regards
