    Host-Controller Interface (HCI) Fundamentals


      Hi everyone,

      I want to learn Host-Controller Interface (HCI) protocol.


      • For testing and debugging, the Component can be configured to HCI mode through a Component embedded UART.
      • The HCI layer implements a command, event, and data interface to allow link layer access from upper layers such as GAP, L2CAP, and SMP.
      • HCI over UART In this mode the BLE host will communicate with the BLE controller via the UART.


      My questions.

      • What are the differences between software HCI - HCI over UART
      • Is there a code sample outside this Day018_Direct_Test_Mode ?
      • What can be done with software HCI - HCI over UART
      • For example, can it be applied Server-Client communication?
