5. Function description

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

operating mode based on user's parameters. During the process, the AUX remains low level. After the process completed,

the AUX outputs high level and starts to work as the operating mode combined by M1 and M0. Therefore, users need to

wait the AUX rising edge as the start of module's normal work.

AUX P is used as indication for wireless sending & receiving 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.

After receiving the valid wireless data, the module will immediately pull AUX low and start UART to output data

and then pull up AUX after the data output is completed.

After receiving the serial port data, the module will immediately pull down AUX and start sending data wirelessly

and after all the data is sent, pull up AUX.
