Extended Scan LE Coded Phy

I am evaluating the nRF5284 SDK 15  Module in HCI mode. I am trying to scan Extended advertise when:

1.Extended non connectable non scannable advertising, Primary_Advertising_PHY=LE 1M and Secondary_Advertising_PHY=LE Coded with or without data , No extended advertising reports received from the scanner.

2.Extended non connectable, non scannable advertising, Primary_Advertising_PHY=LE Coded and Secondary_Advertising_PHY=LE 1M, the scanner crash because no command complete is received during 5 seconds and when the HCI_Reset command is send the events are generated  (TED ==Nordic Scanner nRF5280):

   Event Code = 0x10 (HCI_HARDWARE_ERROR)
   Parameter Total Length = 0x1
   Hardware_Code = 0x1 (HCI synchronization lost)

Is it possible to scan Extended advertise packets in LE Coded Phy and what could cause the error 0x1 ?
