The blu2i Module contains a complete Bluetooth interface and requires no further hardware to implement full Bluetooth communication. The module has an integrated, high performance antenna together with all RF and Baseband circuitry, it interfaces to the host over a straight forward serial port using AT commands. The module runs specific firmware within the Virtual Processor that includes a serial Port Profile and AT command interpreter. The module can be configured so that it can be attached to a ‘dumb’ terminal or attached to a PC or PDA for cable replacement applications.
The module provides access to 5 General I/O lines and 2 analogue I/O lines to provide Bluetooth connection to simple devices such as switches or LEDs without requiring any processing at the module end.
