The device doesn't know - it's the way that the host interprets it.

Hi awneil cound you please help explain my comments？

thank you verymuch

[awneil]

did you read the article I linked, and follow-up on the topics it references?

I don't know any more than that, I'm afraid.

But this would be generic behaviour - not specific to Nordic - so try some general googling ...
