5.6.2 Indication of wireless transmitting
Buffer (empty): the internal 1000 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When
AUX=1, the user can input data less than 1000 bytes continuously without overflow. Buffer (not empty): when
AUX=0, the internal 1000 bytes data in the buffer have not been written to the RFIC completely. If the user starts to
transmit data at this circumstance, it may cause overtime when the module is waiting for the user data, or
transmitting wireless sub package.When AUX = 1, it does not mean that all the UART data of the module have
been transmitted already, perhaps the last packet of data is still in transmission.
