High Speed UART Interface
NEMO uses a standard UART interface for communicating to other serial devices. Four signals
from NEMO implement the UART function. The signal operation amplitude can be varied with the
external +VBT_IO supply pin. This is useful for different systems that support different digital
communication amplitudes such as 3.3V or 1.8V. When NEMO is connected to another digital
device, BT_CTRL_RXD_N and BT_CTRL_TXD_N transfer data between the two devices. The other
two remaining UART pins, BT_CTRL_RTS_N and BT_CTRL_CTS_N, can be used as hardware flow
control signal as used in RS232 communications.
The high speed UART can support up to 4Mbits in throughput which is needed for data transfers
using EDR RF link payloads with 3Mbit over the air throughput. The baud rate and other
configuration parameters can be set via the firmware and PSKEYs during bootup and initialization.
BlueCore Serial Protocol (BCSP)
This document only describes CSR’s BlueCore Serial Protocol overview and does not go into detail
on BCSP implementation, packet structure and stack elements. Please refer to CSR’s “BlueCore
Serial Protocol (bcore-sp-012Pb).pdf” document for more a detailed explanation and
implementation. BCSP must be implemented on the Host to communicate to the NEMO module.
BlueCore Serial Protocol (BCSP) is a protocol used to carry data that flow through a reliable UART
link. The Bluetooth stack has been designed to transfer data between a Bluetooth Host and a
Host Controller (NEMO). The Bluetooth stack is intended to be used to carry the Bluetooth HCI
(Host Controller Interface) protocols plus several others. BCSP is intended to be used with CSR
based Host Controllers (NEMO), which provides hardware to support much of the Bluetooth stack
functionality.
