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
