Hi Zhou Ziyao,

It's in advertising mode, not connected , correct ?
I talked to the developer of the app and it could be a bug.
So for measuring the distance between advertising packet, please use the sniffer.
What exactly you want to measure ? interval between 2 advertising packet or interval between two connection event when in connection ?

Hi,
Please show the full screenshot. If you need to go multiple steps to get there, please take screenshot at each step.
I'm not so sure what the app's measuring here. Most likely it's the distance between advertising packets.

Hi Zhou,

I would suggest you to take a look at our Dev Academy course here: https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/lessons/lesson-6-bluetooth-le-sniffer/

It will show you how to to capture the communication when in connection.
