Firstly if your Nordic device starts advertising right after disconnection then it is written as FEATURE in the firmware. If it is your firmware the you wrote it (or blindly used some library/black-box module, still it's your firmware). Secondly how does button relate to this? Don't mix topics, solve one by one and open new ticket if you have further (unrelated) questions.
