Title Design of hotel Bluetooth lock’s hardware and software
Abstract BLE4.0 Bluetooth low energy technology is consumption with low power. It is a safe,fast technology and it also has many other advantages that being used for themajority of factories and users. Google supported the movement of developing ofBluetooth 4.0 on the Android4.3 platform on July, 2013. Therefore, Bluetoothtechnology has won great opportunities. In this paper, the concept of mobile andBluetooth piconet BLE4.0 structure is based on low-power Bluetooth technology andBLE4.0 Android operating system for mobile terminals. Its’ connection andcommunication is achieved by designing the applications.This paper firstly wrote the structure and principles of each layer of BLE4.0Bluetooth low energy of the protocol stack. Thereafter, the article describes thecommunication chip CC2540 Bluetooth module. And using the system OSAL event helpsto deal with the stack events. The android mobile terminal side and Bluetoothinterface is connected by the programming software. Finally, the article describesthe choice of Antenna - ceramic antenna, through its cost-effective and intelligentBluetooth lock condition. It met the designing requirements and it can be usedas the operating system of the antenna.This paper presents the design and the ability to communicate effectively thatconnect Android mobile terminal and Bluetooth low energy devices. Various surveysand studies showed that low-power Bluetooth technology has broad prospects in thefuture.
