Research And Implementation Of Blluetooth4.0Core Protocol

Bluetooth4.0core protocol is the latest Bluetooth core specification by BluetoothSIG. It is updated from Bluetooth high speed core protocol3.0+HS version and it includesClassic Bluetooth, Bluetooth high speed and Bluetooth low energy protocols. Bluetoothhigh speed is based on Wi-Fi, and Classic Bluetooth consists of legacy Bluetooth protocols.and Bluetooth low energy protocols is the new hallmark feature of Bluetooth4.0, whichwill enable devices requiring low cost and low power wireless connectivity to use newBluetooth standard.Based on development of Bluetooth4.0SoC firmware, the paper analyzes theprinciple of Bluetooth4.0low layer core protocol and relevant protocol implementation. Inaddition, the paper mainly discussed the general methods and strategies of the realizationblutooth protocol, and then it propsed a dynamic scheduling algorithm about BluetoothPiconet baseband resource management. For Bluetooth and WLAN coexistence, it gives acomination method of AFH and BT、WLAN timeshare work scheme.The significance of the research is that it is initiated by local enterprise to developnew product which achieves the newest International technical specifications. This willhelp our country to master advanced technology in information industry, and promote thedevelopment and progress of the integrated circuit enterprises in China.
