I'm working on the split-LL BLE stack 
implementation currently, but that is for the "Single Chip"
From what you describe, it sounds as though you
would like to use the SoC as a BLE coprocessor, either over
UART or SPI or something. Is that correct? In that case there
may be a way to add a vendor-specific HCI command  or
simply call the command from within your application.
Yes, I will use the Bluetooth chipset with HCI over UART connection.
I will check your advice.
