关于CC3220SF 的uartecho 例程我无法读取Rx 的数据？

/*!
 *  @brief  Function that reads data from a UART with interrupt enabled.
 *
 *  %UART_read() reads data from a UART controller. The destination is specified
 *  by \a buffer and the number of bytes to read is given by \a size.
 *
 *  In #UART_MODE_BLOCKING, %UART_read() blocks task execution until all
 *  the data in buffer has been read.
 *
 *  In #UART_MODE_CALLBACK, %UART_read() does not block task execution.
 *  Instead, a callback function specified by UART_Params::readCallback
 *  is called when the transfer is finished.
 *  The callback function can occur in the caller's context or in HWI or SWI
 *  context, depending on the device-specific implementation.
 *  An unfinished asynchronous read operation must always be canceled using
 *  UART_readCancel() before calling UART_close().
 *
 *  %UART_read() is mutually exclusive to UART_readPolling(). For an opened
 *  UART peripheral, either %UART_read() or UART_readPolling() can be used,
 *  but not both.
 *
 *  @sa UART_readPolling()
 *
 *  @param  handle      A #UART_Handle returned by UART_open()
 *
 *  @param  buffer      A pointer to an empty buffer to which
 *                      received data should be written
 *
 *  @param  size        The number of bytes to be written into buffer
 *
 *  @return Returns the number of bytes that have been read from the UART,
 *          #UART_STATUS_ERROR on an error.

uartecho例程调用uart_read函数等待键盘的输入，在发送给终端XDS110

是的

我传感器回发的的数据是二进制数，并没有换行符和新行，所以uart一直是阻塞的，那如何设置UART接收二进制数在不遇到、换行符就返回呢？
