CSR Bluetooth Software Stacks
9.2 BCHS Software
BlueCore Embedded Host Software is designed to enable CSR customers to integrate Bluetooth functionality into
embedded products quickly, cheaply and with low risk.
BCHS is developed to work with CSR's family of BlueCore ICs. BCHS is intended for embedded products that
have a host processor for running BCHS and the Bluetooth application, for example a mobile phone or a PDA.
BCHS together with the BlueCore IC with embedded Bluetooth core stack (L2CAP and Service Discovery
Protocol, SDP) is a complete Bluetooth system solution from RF to profiles.
BCHS includes most of the Bluetooth intelligence and gives the user a simple API. This makes it possible to
develop a Bluetooth product without in-depth Bluetooth knowledge.
The BlueCore Embedded Host Software contains three elements:
! Example drivers (BCSP and proxies)
! Bluetooth profile managers
! Example applications
The profiles are qualified which makes the qualification of the final product very easy. BCHS is delivered with
source code (ANSI C). Example applications in ANSI C are included with BCHS, which makes the process of
writing the application easier.
9.3 Additional Software for Other Embedded Applications
When the upper layers of the Bluetooth protocol stack are run as firmware on BlueCore4-ROM CSP, a UART
software driver is supplied that presents the L2CAP and SDP APIs to higher Bluetooth stack layers running on
the host. The code is provided as ‘C’ source or object code.
9.4 CSR Development Systems
CSR’s BlueLab and Casira development kits are available to allow the evaluation of the BlueCore4-ROM CSP
hardware and software, and as toolkits for developing on-chip and host software.
