@Jeffrey Tang: I also don't have any other suggestion than using 2 instance of the sniffer (with 2 dongle). Our sniffer currently when following a connection won't be able to capture other advertising packet. I don't know much about our plan in the future version of the sniffer.

But what you can do is to sync them using a advertising packet from the peripheral before it enters connection mode (Set time reference). Both 2 sniffers should be able to capture this packet. And then you can maybe merge the two traces together base on this relative timing.

two sniffers are not sync to each other, so still cannot figure out the interval between a packet A received on sniffer #1 and another packet B received on sniffer #2.

Perhaps you could obtain a second sniffer dongle and run 2 instances of the sniffer, instructing one not to follow connection packets. This may or may not require two instances of wireshark.
