Bluetooth is a wireless protocol that uses a 2.4 GHz radio frequency to communicate among devices within a 30 to 40-foot range. Initially developed to communicate wirelessly with cellular phones, PDAs, and laptop computers, the Bluetooth simple protocol and ease of implementation make it ideal for wireless communication across a diverse set of products in many industries. Engineers are now using Bluetooth to develop remote data acquisition and instrument control applications. The release of LabVIEW 7.1 includes a new set of Bluetooth Compatibility VIs with which LabVIEW developers can build custom Bluetooth applications. This application note demonstrates how to build a LabVIEW application to communicate with Bluetooth-enabled devices.
