The module is qualified to Bluetooth Version 2.0. The BISM2 Bluetooth Serial Module is one of the most compact complete Bluetooth solutions, making it ideal to integrate into handheld devices. Another version of the BISM2 module is available that retains the same board size, mounting holes, and connector as the previous Bluetooth module from Laird, allowing users to access the improved radio performance and functionality without the need for any PCB modifications. The BISM2 module is based on Cambridge Silicon Radio’s BlueCore 04 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 BC04 chipset implements the higher layer Bluetooth protocol stack, up to and including the Generic Access Profile (GAP), Service Discovery Profile (SDAP), Serial Port Profile (SPP), Dial Up Networking (DUN) profile, Headset Profile (HSP), Hands Free Profile (HFP), File Transfer Profile (FTP) and Audio Gateway. A virtual processor within the BC04 implements 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 is available for fast product evaluation and development. An alternative version of firmware is available that provides multi-point programming support. The module can be configured so that it can attach to a ‘dumb’ terminal or attach to a PC or PDA for cable replacement applications. In addition to the Bluetooth functionality, The BISM2 module provides access to 9 General I/O lines and 2 analogue input and output lines. These can be configured to provide connection to simple devices, such as switches or LEDs, without requiring any external processing. Both the GPIO and ADC lines can be accessed either via the wired host UART connection, or remotely over the Bluetooth link. The BISM2 module is supplied in a small form factor PCB (22.0 mm x 34.0 mm x 7.6 mm), that connects to a main PCB using a 40-way Hirose connector. The interface is compatible with the BISM1 module. 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 4 mW. Support is provided for low power modes that make the BISM2 particularly applicable to battery powered installations. The BISM2 module is lead-free, RoHS compliant, and supports an industrial temperature range of -40°C to +85° C. 1.1 Applications POS equipment Medical equipment Telematics Voice applications Industrial automation Automotive applications |
