General Description
Ezurio’s Embedded Intelligent
Bluetooth
Serial Module is a fully integrated and qualified Class 1
Bluetooth
solution
designed for lowest cost of integration and ownership for designers wishing to include
Bluetooth
functionality in
their products. The module is qualified to
Bluetooth
Version 2.0.
The Embedded Intelligent
Bluetooth
Serial Module is designed to give a rugged solution that is ideal for industrial
automation and ruggedised handheld devices. It works over a wide temperature range of -40°C to +85°C. The
physical form of the module allows designers to mount the antenna section of the module outside a screened
enclosure.
The Embedded Intelligent Serial Module is based on Cambridge Silicon Radio’s BlueCore4 chipset. The module
contains all of the hardware and firmware for a complete
Bluetooth
solution, requiring no further components.
The Module has an integrated, high performance antenna which is matched with the
Bluetooth
RF and baseband
circuitry. The firmware integrated into the module implements the higher layer
Bluetooth
protocol stack, up to
and including the Generic Access Profile (GAP), Service Discovery Profile (SDAP), Serial Port Profile (SPP) and
Audio Gateway. A virtual processor is used within the BC04 to implement an AT command processor. This
interfaces to the host system over a straight forward serial port using an extensive range of AT commands. The
AT command set abstracts the
Bluetooth
protocol from the host application, saving many months of programming
and integration time. It provides extremely short integration times for data oriented cable replacement and voice
applications. A low cost development system and integrated RS232 products with the same firmware are
available for fast product evaluation and development.
An alternative version of firmware is available that provides support for multi-point applications.
The Module can be configured so that it can be attached to a ‘dumb’ terminal or attached to a PC or PDA for cable
replacement applications.
In addition to the
Bluetooth
functionality, The Embedded Intelligent Serial Module provides access to 6 General
I/O lines and one ADC input. These can be configured to extend the UART control or to provide connection to
simple devices such as switches or LEDs without requiring any external processing. The GPIO lines can be
accessed either via the wired host UART connection, or remotely over the
Bluetooth
link. Support is also provided
for a PCM connection to an external audio codec.
The Embedded Intelligent
Bluetooth
Module is supplied in a small form factor PCB (17.7mm x 46.0mm x 5.0mm),
that solders directly. The module includes a high sensitivity, high gain antenna which provides excellent range.
Typical open field performance provides ranges of over 250 metres at transmit powers of 4mW.
Support is provided for low power modes that make the Embedded Intelligent
Bluetooth
Module particularly
applicable to battery powered installations.
The Embedded Intelligent
Bluetooth
Module is Lead-free and RoHS compliant and supports an industrial operating
temperature range of -40°C to +85°C.
