Virtual Instrumentation Approach for ClientServer Interfacing of Bluetooth using LabVIEW
Keywords:
Communication protocols, Virtual instrumentation, Bluetooth client, Bluetooth server, SDP (Service Discovery Protocol), RFCOMM (Radio Frequency Communication)Abstract
Bluetooth is one of the most widely wireless ad hoc networks used. Bluetooth devices operate at 2.4GHz,
in the globally available, license-free, ISM band and they use FH-CDMA technique because of its inherent
interference rejection capability. The problem with Bluetooth is low date rate and distance between the
devices is less. In this article we will discuss how the communication is done in lab view with Bluetooth
through client server application. As LabVIEW is good for communication between the devices as it has
many communications protocol features built in it. When you are actually writing the application, you
have more flexibility in choosing a protocol. Factors that affect your protocol choice include the type of
machines the processes will run on, the kind of hardware network you have available, and the complexity
of the communication that your application will need. Several protocols are built into LabVIEW, some of
which are specific to a type of computer.
