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.
