CSR Bluetooth Software Stacks
BlueCore4-ROM is supplied with Bluetooth v2.1 + EDR compliant stack firmware, which runs on the internal RISC
microcontroller.
The BlueCore4-ROM software architecture allows Bluetooth processing and the application program to be shared in
different ways between the internal RISC microcontroller and an external host processor (if any). The upper layers of
the Bluetooth stack (above HCI) can be run either on-chip or on the host processor.

Figure 8.1: BlueCore HCI Stack
In the implementation shown in Figure 8.1 the internal processor runs the Bluetooth stack up to the Host Controller
Interface (HCI). The Host processor must provide all upper layers including the application.
