5.6 AUX description

AUX Pin can be used as indication for wireless send & receive buffer and self-check.

It can indicate whether there are data that are not sent yet via wireless way, or whether all wireless data has been sent
through UART, or whether the module is still in the process of self-check initialization.
5.6.1 Indication of UART output

To wake up external MCU
5.6.2 Indication of wireless transmitting

Buffer (empty): the internal 1024 bytes data in the buffer are written to the RFIC (Auto sub-packaging).

When AUX=1, the user can input data less than 1024 bytes continuously without overflow. Buffer (not empty): when
AUX=0, the internal 1024 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.
