Hi Thomas,
I'm not so sure which filter you are asking about.
But to be able for the sniffer to follow a connection, you would need to select the advertiser. It can only follow one advertiser/connection at a time, so you need to select the advertiser in advance.

Hi Hung,

Thank you very much it is working, for my understanding, why it doesn't work with the filter?

Regards,

Thomas.

Hi Thomas,
I would suggest you to go through Lesson 6 in our Bluetooth Academy here: https://academy.nordicsemi.com/lessons/lesson-6-bluetooth-le-sniffer/

It lesson 6 I explained how to use the sniffer to follow a connection. At exercise 2 Step 6 you can find how you can apply a filter.

Hello,

I found the right filter for advertisement

btle.advertising_address == mac address, it is working fine

But I can't find the right filter for the other exchanges, pairing, data, here it is only for advertising.

Do you have a list of filter commands please? I'm looking for all exchanges based on one MAC, and it looks different from the standard one used with other devices with wireshark
