Sniffer2 Problem: Can not get the right “Interval"

[Andre]

HI

I used the sniffer to get the packes of the connect, but  I have some problem. As the Fingure indicats, The master set the Interval to 10ms, but the Packet Says the Interval is 100ms， I can not understand what is wrong...my board is PCA10004, wirshark version is 2.6.4..I try some other "master and slave" and could get the same problem

I tested the same connection using Sniffer1 a moment ago, There was no the same problem

I tested to get some Adv Pakets using Sniffer2, the 100ms gap may always appears.  Is it the bug or limit  of the Sniffer2 ?

Hi,

You need to look at the "delta time" found in the Nordic BLE Sniffer data. The time stamp on the Time column is not reliable since it's the time stamp on UART on PC.

In the screenshot below the connection interval is 48.75 ms (48520+230 µs)
