2i
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.
