RE: Setting Non-Connectable and Scannable Extended Advertising in NCS v2.5.0 (nRF52840)

Hello qianjunwang,

With Scannable Undirected Extended Advertising, you cannot have Advertising Data. The idea with Extended Advertising is that data can be offloaded entirely to the Scan Response.

You will need to remove the Advertising Data.

By the way, I see that a lot of error returns are not properly handled in your application. That hinders debugging. I recommend fixing that, and you will also be able to get a lot of clues from the log.
