The Bluetooth wireless technology is the new short-range RF transmission standard for low-power, low-cost, short-range radio links between mobile devices and electric product. The technology can eliminate the confusion of cables, connectors and protocols confounding communications between devices. Mobile phones, pagers, laptops, PDAs, digital cameras and more, all now have a common structure for communicating across their product platforms. In this paper, we present the Bluetooth protocol stack and headset profiles for the communication between mobile phone and headset. And then, we construct application software which is embedded in the device that operates an application over the Bluetooth protocol stack Next we implement wireless headset using MSP430, not real time operating system.

Recent advancement in RF technology and wireless communications has enabled the development of noble networks. Bluetooth that can be used in various application field is a kind of WPAN(Wireless Personal Area Network) standard that is widely known. Bluetooth enables voice and data applications to operate simultaneously. Various applications have been implemented based on standard Profiles. In this paper, we describes the development of Biuetooth network AP(Access Point) system for network connection of Bluetooth devices. Unlike headset, mouse, and keyboard, the access point should have capability to support multiple connection and stabilized network throughput. We have designed and developed the hardware system, core stack and profiles on embedded system to comply with standard specification. Our system showed compatibility and good protocol performance through testing with lots of products that is available in market.
