• Description: Blue Core ROM Plug-n-Go
• Manufacturer: CSR

9
BlueCore4-ROM Plug-n-Go is supplied with Bluetooth v2.0 + EDR compliant stack firmware, which runs on the internal
RISC microcontroller.
The BlueCore4-ROM Plug-n-Go 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.
9.1
In the implementation shown in Figure 9.1 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.
