To overcome the problems exercising in automatically connection between electronic equipments, such as slow speed of the Bluetooth device connection and the redundancy of operation, a new method for accelerating the Bluetooth connection with near field communication (NFC) technology is proposed. Instead of the traditional Bluetooth, the NFC technology based on Android system is used to complete a series of tedious works before data transmission, including equipment search, selection, matching, and security detection, etc. By using the features of NFC, i.e., point to point communication and high speed data transmission, the search time of Bluetooth is substantially reduced, and the exchange of PIN codes is realized. With the advantage of NFC for shortening the communication distance, ECC encryption algorithm and the technology of reading SIM security code via Android system, the security of the connection is strengthened. The experimental results verify the feasibility and safety of applying this method in automotive Bluetooth connection; and indicate that the method greatly reduce the Bluetooth connection time, and enhance the security of connection.

Dawei always strives to provide better experience to our client, we developed our new Bluetooth Speaker #SK09 with NFC technology. If your smart phone NFC-enabled, simply turn on the NFC and gently bump your phone against the NFC logo, the LED indicator will be solid blue and a beep will be triggered to indicate a successful connection. (Due to compatibility issue, some NFC-enabled devices may not work with the speaker)
