Extended Advertisement with Scan Response

Question

Target: nrf52 dev kit 
 Soft device: s132_nrf52_7.2.0_softdevice.hex 
 SDK: nrf5 sdk 17.1.0 
 Environment: IAR 
 Example modified: ble_app_rscs I am trying to modify the example to support extended advertisement with scan response. In the following example init function if I set ble_adv_extended_enabled to false it will allow the advertising and scan response data sets. If I set ble_adv_extended_enabled to true and remove the initialization of the scan response encoding, that will also run. 
 Please advise on the configuration to allow extended advertisement with scan response. 
 Thanks
