Softdevice Serialization (Rpc) Spi Example

Question

I found the Ble Serialization here and the example sourcecode within the sdk sources. 
 It uses uart with 38.400 Baud and hardware handshake (Rtc/Cts). 
 Is there also example code available for using the Spi interface?

Hi, 
 there are couple of physical transport layers available for serialization: SPI (6 wires - additional request,ready lines), SPI (5 wires - additional request line), UART, reliable UART (HCI transport) and low power UART (to be used only with STM MCU as application). Documented here .
