EZURiO Bluetooth PC Card with embedded stack Part Number BISPCO1BI 1 General Description Ezurio s blu Bluetooth PC Card is designed for users who want the functionality of a Bluetooth PC Card but without the need or ability to run a host Windows Bluetooth stack on their system The blu Bluetooth PC Card is unique in providing a complete Bluetooth stack embedded within the card appearing as a Serial Port to the host system The blu Bluetooth PC Card provides a fully integrated Class 1 Bluetooth solution that is qualified to Bluetooth Version 1 1 The Bluetooth functionality is accessed using a highly developed and extensive set of AT commands which result in very fast design and integration cycles The integrated stack also provides a significantly more robust solution than conventional cards that use a Windows host processor stack providing options for both hard and soft reset Auto connect functionality built into the card can be used to ensure reconnection to other serial based devices This makes the blu Bluetooth PC Card particularly suitable for streaming applications such as connection to Bluetooth GPS receivers The blu Bluetooth PC Card is based on Cambridge Silicon Radio s BlueCore 02 chipset The firmware integrated into the BCO2 chipset implement the higher layer Bluetooth protocol stack up to and including the Generic Access Profile GAP Service Discovery Profile SDAP Serial Port Profile SPP and
