I am trying to connect with pair the device to the mobile and every time i need to do whitelist advertising to the paired devices

Hi,

Did you see the same behavior when testing with our other out-of-the-box samples as well?

And did you do any modifications to the template sample?

Kind regards,
Andreas

Hi Andreas
On Matter samples I got error like this . pairing gets rejected
I didn't do modifications to the code.

also have a doubt why  the Matter samples only implemented in CPP ?

Hi,

From the logs we do see: "[11:21:00:626] I: 161567 [DL]BLE GAP connection terminated (reason 0x13)", which indicates that it is a mobile phone which disconnects immediately.

I have some more questions for you

1. Can you explain what you mean when you say "pairing"? 
2. Which apps are you using for the procedure?
3. Can you link to the guides you've been following? 

Kind regards,
Andreas
