@flynnnn: If possible please upload the full sniffer trace. I can see the sniffer didn't capture all the packet sent from master every connection interval, lots of packets was missing. It could be either issue with the master, or issue with sniffer (too far from master for example). Which master device did you use ? Which board did you use for peripheral ?

@flynnnn: If it's fixed please accept the answer and/or close the case.
