the meaning of delta time in Nordic ble sniffer meta

[danielkelly]

I have captured the ble packet showing as the screenshot by using the ble sniffer(win7 ) and wireshark. But I did not understand the meaning of delta time (such as end to start, start to start ). Please help to explain it. or Is there a specification for Nordic ble sniffer meta ?

Thanks

Well there aren't very many things it could mean. "us end to start" means microseconds from the end of the last packet to the start of this packet and "us start to start" obviously means microseconds from the start of the last packet to the start of this one.

There's an API guide in the package you downloaded where the 'end to start' figure is defined, the 'start to start' is just added in by the dissector to be helpful.

Yes it is like RK says, time from the start/end of last packet to the start of this packet.
