5. Functional Details

When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating

mode on the basis of the user parameters. During the process, the AUX keeps low level. After the process completed, the

AUX outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, the user needs

to wait the AUX rising edge as the starting point of module's normal work.

AUX Pin can be used as indication for wireless send & receive buffer and self-check.



It can indicate whether there are data that are yet to send 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.

After the module receives valid wireless data, it will immediately pull down AUX and start the serial port output data.

After the data output is completed, AUX is pulled. high.

Buffer (empty): the internal 80 bytes data in the buffer are written to the RFIC (Auto subpackage). When AUX=1, the

user can input data less than 80 bytes continuously without overflow.

Buffer (not empty): when AUX=0, the internal 80 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 subpackage.

Notes: 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.
