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

Question

Hi，

When I use NCS V2.5.0 （board：nRF 52840），I want to set the Non-Connectable and Scannable Extended Advertising.My code as follows.I use the APP nRF Connect for moblie，but it can‘t scan the adv.I also use the Ellisys BTR（Picture shows 'Test Packet'），How can I set the Non-Connectable and Scannable Extended Advertising？
