There was a problem hiding this comment. The comment on line 9 mentions '4 gives one each of legacy, 2M, 1M and Coded PHY advertising sets' but the configuration is set to 2, creating a mismatch between documentation and actual value.

There was a problem hiding this comment. No not all vendors will support 4 as default.

There was a problem hiding this comment. I think the issue is that the comment states "Increased to 4" but the option assigns 2

There was a problem hiding this comment. I still don't think the comment makes a lot of sense. Why is the comment even mentioning 4 sets, if we are configuring for 2 sets? |

It is followed across the net, drivers and bluetooth subsystem... and KConfig settings too refer to
applications can have SoC overlay configuration that is applied to itor phrase likeoverlay configuration fileshere: https://docs.zephyrproject.org/latest/build/kconfig/setting.htmlHence, outside the scope of this PR. You may request a github issue to update rest of the repository and Kconfig settings documentation with a suitable proposal.
