You can use RFCOMM or OBEX to send and receive files between Bluetooth devices.
可以采用rfcomm或obex在蓝牙设备之间发送和接收文件。
The RFCOMM module and the user mode dund daemon implement Bluetooth dialup networking.
RFCOMM模块和用户模式dund后台进程实现了Bluetooth拨号网络。
In the real world, RFCOMM should be used when you want to take a traditional serial port application and make it Bluetooth-enabled.
在现实世界中，如果想使用传统的串口应用程序，并让它能使用蓝牙，就应当使用RFCOMM。
RFCOMM is known as the virtual serial port protocol because it allows a Bluetooth device to simulate the functions of a serial port.
RFCOMM称作虚拟串口协议(virtualserialport protocol)，因为它允许蓝牙设备模拟串口的功能。
The OBEX protocol layer is implemented above the RFCOMM layer and is useful when you want to transfer data as an object, such as files.
OBEX协议层是在RFCOMM 层上面实现的，如果想把数据以对象（例如文件）的形式传输，那么 OBEX很有用。
However, RFCOMM is the better choice when you want to send and receive stream data, just like you would with a traditional serial port.
但是，如果想发送和接收流数据，则RFCOMM是更好的选择，就像使用传统的串口一样。
The Bluetooth protocol stack lets you use several methods, including RFCOMM and Object Exchange (OBEX), to send and receive files between devices.
蓝牙协议栈允许采用多种方法，包括rfcomm和objectExchange (OBEX)，在设备之间发送和接收文件。
RFCOMM is better when you want to send and receive stream data (and when you'd like to take a traditional serial port application and Bluetooth-enable it).
如果想发送和接收流数据（而且想采用传统的串口应用程序，并给它加上蓝牙支持），那么 RFCOMM更好。
Let's take a look at two simple protocols in the stack used to send data, RFCOMM and OBEX, and compare the advantages and disadvantages of using them when transferring files.
我们先来看看栈中用来发送数据的两个简单协议RFCOMM和OBEX，并比较使用它们传送文件的优势和不足。
