The firmware supplied within this device offers a complete Bluetooth (v1.1) stack including profiles and command The National Semiconductor LMX9820 BluetoothTM Serial interface. This firmware features point-to-point and pointPort module is a highly integrated radio, baseband control- to-multipoint link management supporting data rates up to ler and memory device implemented on an LTCC (Low the theoretical maximum over RFComm of 704 kbps. The Temperature Co-fired Ceramic) substrate. All hardware internal memory supports up to three active Bluetooth and firmware is included to provide a complete solution links. from antenna through the complete lower and upper layers of the Bluetooth stack, up to the application including the 1.1 APPLICATIONS Generic Access Profile (GAP), the Service Discovery Application Profile (SDAP), and the Serial Port Profile (SPP). Personal Digital Assistants The module includes a configurable service database to POS Terminals fulfil service requests for additional profiles on the host. The LMX9820 features a small form factor (10.1 x 14.0 x Data Logging Systems 1.9 mm) design; thus, solving many of the challenges associated with system integration. Moreover, the LMX9820 is pre-qualified as a Bluetooth Integrated Component. Conformance testing through the Bluetooth qualification program enables a short time to market after system integration by insuring a high probability of compliance and interoperability.
