Our Bluetooth pedigree - Cambridge Consultants

Bluetooth expertise from Cambridge Consultants
Our Bluetooth ® Pedigree
Extensive set of profiles and protocols supported by Cambridge Consultants’ Bluetooth software
Our software provides the widest range of profiles and portability. We have been actively developing Bluetooth
software and products for over a decade. We offer a proven Bluetooth protocol stack (BlueStack ® ) and a profile
library (Interface Express ® ) to enable the implementation of Bluetooth applications. We can also offer Bluetooth
technical support services to help you develop high-quality Bluetooth products with highly competitive costs.
The qualified profiles and underlying protocols supported by our software are:

Embedded Bluetooth applications for CSR’s BlueCore
The transport mechanism to exchange messages for controlling A/V devices
Defines the mechanism for A/V stream negotiation, establishment and
transmission procedures
Used to transport common networking protocols over the Bluetooth media such as
IPv4 and IPv6
Transfer protocol that defines data objects and a communication protocol two
devices can use to exchange those objects
The call control signaling for the establishment of speech and data calls between
Bluetooth devices
Emulates the serial cable line settings and status of an RS-232 serial port and is
used for providing serial data transfer
We have a unique relationship with CSR that enables us to produce binary images for CSR’s BlueCore family of
devices. Through this, we can develop applications targeted natively at the XAP2 RISC processor embedded
within all of CSR’s BlueCore devices. This removes the need for a host processor, so reducing the cost of
products developed in this way. In fact, XAP is our own family of processor cores. We can extend this capability to
our customers who licence our “xIDE for Interface Express ” toolkit. The embedded applications produced using
this approach are performance optimised.
Our Bluetooth experience
We have developed a wide range of Bluetooth ® applications, including:
• A Medical device platform called VENA, which is continua compliant
• An Internet enabled device platform called CatchNet
• A low-cost Cordless Telephony (CTP) Access Point reference design
• A Bluetooth ® meter-reading interface
• A Bluetooth ® -accessible memory stick, making use of BIP to transfer images from cameras etc. to the memory
stick that can be read via the USB interface by most PCs.
• A low-cost Bluetooth ® hands free kit, where combined Hands-Free and Sync profiles exist on the BlueCore -
allowing the car kit to read the phonebook and provide audio service
• A Bluetooth ® intercom system
• A general purpose configurable Bluetooth ® network node (the SP/AT device). This enables, via the serial port
and an extended AT command set, the establishment of sophisticated functions, such as establishing audio
connections between SP/ATs etc.
• A Bluetooth ® Media gateway
The scope of applications that can be supported by Bluetooth ® is very wide. Our team working on Bluetooth ®
projects has expertise in the specifics of each application area. Once we understand what you wish to achieve,
then we can call upon their expertise to support you.
Whether it is to reduce the cost of an existing solution, add Bluetooth to an existing product, or to implement a new
or unusual application, Cambridge Consultants is the best choice for achieving your goals.
