2 HARDWARE OVERVIEW.
The CSR CASIRA Bluetooth Development kit has been developed primarily to assist
CSR’s customers in the development of host-side software and external radio circuits
outside the BlueCore
TM
ICs. It will also be used to assist CSR’s customers to evaluate
the BlueCore
TM
chips. The Evaluation system consists of two identical modules that
allow the user to send both data and voice over a Bluetooth link. Each unit is driven
from a PC for data connections and from a headset (supplied with the kit) for voice
connection.
Each unit consists of a motherboard and a Bluetooth radio transceiver daughter card
module. The first radio module shipped with the system uses the CSR BlueCore01
chip and also includes the front-end filter, an LNA, a PA, a TX/RX switch, a flash
memory, a crystal and an external (connectorised and detachable) antenna. The radio
module plugs into the motherboard. Hardware upgrades will be shipped in the format
of a new replacement radio module when new versions of the CSR BlueCore IC
product range become available. The motherboard provides a serial port (RS232), SPI
port, USB port, PCM port, power supply socket and audio socket.
The on-board CODEC can be used for the voice interface although it is possible to
connect direct to the PCM connection via the internal Molex connector. The signal
