Hi, 
 If you want to use CAF you can read documetnation for the CAF advertisign module here . Note the link to this page about advertising providers. So if you want to set the advertising/scan response data, you must register a callback with BT_LE_ADV_PROV_AD_PROVIDER_REGISTER and BT_LE_ADV_PROV_SD_PROVIDER_REGISTER. You can see an example of this being done in nrf/samples/bluetooth/fast_pair/input_device/src/bt_le_adv_prov_uuid16.c. 
 Without CAF you could reconfigure advertising using for instance a delayable work queue item, or a delay if you have a thread not doing anythign else. There, stop and re-start advertising with parameters to modify the advertising interval. CAF certeinly has its's uses, but if this is all you want, then I would suggest that as a simpler approach.
