Bluetooth has been one of the best trustable short distance wireless communication systems
that can be accessed and used very easily. It is envisaged that it will allow for the replacement
of the many propriety cables that connect one device to another with one universal radio link.
Its key features are robustness, low complexity, low power and low cost. Designed to operate
in noisy frequency environments, the Bluetooth radio uses a fast acknowledgement and
frequency hopping scheme to make the link robust. In this work, a telemetry/PLC Bluetooth
based system will be introduced and described. The system is a general data acquisition and
control system that may be used in several application in industry , biomedical equipments ,
building management systems and Car Area Networks ( CANs) . The system described is
completely built using the AT 89C52 μ-controller and the Blu2i Bluetooth module from TDK
system. Example of applications of the system are in security, home appliances control, and
remote data acquisition .Experimental work confirm the estimated system performance .
