Access via Bluetooth: After a connection to the VAS 5054a has been set up, the Bluetooth software provides a virtual serial COM port (Bluetooth serial port Profile).
通过蓝牙进入:当一个与VAS 5054a的连接建立后,蓝牙的软件会提供一个虚拟的串口。
Like other profiles built on top of the serial port profile, the virtual serial link created by the lower layers of the Bluetooth protocol stack is transparent to applications using the DUN profile.
和其他建立在串口配置文件之上的配置文件一样,被更低层蓝牙通信协议实现的虚拟串行链接对使用DUN配置文件的应用程序是透明的。
As such, the profile allows legacy applications to use Bluetooth as if it were a serial-port link, without requiring any modification.
照这样,这个配置文件支持了旧的应用程序使用蓝牙就像是用串口链接,且不需要任何修改。
