CSR BLUETOOTH SOFTWARE STACK
NEMO is supplied with the CSR BlueCore 6 ROM chip. CSR’s BlueCOre 6 ROM contains the lower
layers of the Bluetooth stack. The stack is Bluetooth v2.1+EDR compliant and runs on the internal
RISC microcontroller within BlueCore. The implementation shown below illustrates the internal
processor of BlueCore running the Bluetooth stack up to the Host Controller Interface (HCI). The
external host processor, external to NEMO, must provide all the upper layers of the Bluetooth
stack including the application.
