类 com.UniPRT.Sdk.Comm.BTClassicConnection 继承关系图:

Public 成员函数
	BTClassicConnection (String descriptor)
	根据 descriptor 字符串初始化新实例。更多...

	BTClassicConnection (long bt_address)
	根据 macAddress 初始化新实例。连接前需先与打印机进行蓝牙配对。更多...

int	BytesAvailable ()

String	Descriptor ()

boolean	Connected ()

void	Close ()

void	Open ()

byte[]	Read ()

void	Write (byte[] dataOut)

Public 成员函数继承自 com.UniPRT.Sdk.Comm.AComm
void	Read (OutputStream binDataIn) throws IOException

void	WaitForData (int msTimeOut)
	等待当前线程有可用数据 BytesAvailable。当前线程会休眠直到接收到数据或超时为止。此为阻塞调用。更多...

void	Write (InputStream binReader) throws IOException
	从输入流写入输出流。更多...

void	WriteAndWaitForResponse (OutputStream binDataIn, InputStream binDataOut, int responseStartTimeOut, int responseEndTimeOut, String completetionToken) throws IOException
	将 binDataOut 流数据写入输出流，并将接收到的数据返回到 binDataIn 流中。返回的数据是收到的数据或收到的完成标记。等待响应超时后返回。更多...

byte[]	WriteAndWaitForResponse (byte[] dataOut, int responseStartTimeOut, int responseEndTimeOut, String completetionToken) throws IOException
	将字节数据写入输出流并返回接收到的数据。返回的数据是接收到的任何数据或收到的完成标记。等待响应超时后返回。更多...

静态 Public 成员函数
static long	DescriptorValidate (String descriptorHint)
	验证 descriptorHint 中的描述字符串是否有效，可能包含或不包含 v_id 和 p_id。返回 long 值。更多...

Private 属性
BluetoothAdapter	mBluetoothAdapter = null

BluetoothSocket	btSocket = null

OutputStream	OutStream = null

InputStream	InStream = null

long	_bt_address

静态 Private 属性
static final UUID	MY_UUID_SECURE = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")
